Keiko Dies
A little more than a year after being set free, Keikostar of the
film "Free Willy"died in the evening on Friday, December
12 to the surprise of his trainers and caretakers. They report that up
until 24 hours before his death, Keiko was doing well and going about his
usual routine. It was only last Thursday that he started showing signs of
lethargy and loss of appetite. His behaviour was abnormal and his
breathing rate had changed. Dr. Lanny Cornell, the veterinarian in charge
of Keiko, affirms that the orca definitely succumbed to acute pneumonia.
However he points out that Keiko was 27 years old, which is quite old for
a captive orca. Orcas live an average of 35 years in the wild.
Keiko, which signifies "the lucky one" in Japanese, was
captured in Icelandic waters in 1979 and sold to the water park industry.
The success of the film "Free Willy" in the early 1990s
stimulated a wave of sympathy for the orca that was in captivity in a
water park in Mexico. In 1996, Willys destiny became Keikos
destiny. The Ocean Futures Society initiated a very costly world
première: the freeing of an orca. From 1996 to 2002 Keiko was
rehabilitated and trained first in Newport, Oregon and then in an
open-ocean pen in Iceland to be later returned to the wild. In July of
2002, he left his pen and joined up and travelled with a group of wild
orcas for a few weeks. Less than two months later, he was found alone in a
Norwegian fjord more than 1000 km from his Icelandic pen. He was seeking
human contact. Since then, Keiko has lived in Taknes Fjord in Norway where
a team of specialists has been taking care of him. Keikos story
raises questions about the feasibility of this type of operation.
Keikos support team had hoped that one day the orca would reunite
with other orcas and return once and for all to the wild. The whales
carcass was buried near the bay where he had attracted thousands of
curious visitors from the four corners of the world. There was a private
ceremony that included only Keikos support team. [HSUS, CNN, BBC]

Use of Driftnets Now Banned in Mediterranean
During its most recent meeting in Dublin, Ireland, the International
Commission for the Conservation of Atlantic Tuna (ICCAT) adopted a
complete ban on the use of driftnets in the Mediterranean. The European
Union (EU) had already adopted a similar ban in 2002, however non-member
countries were not obliged to comply. As of now, all Mediterranean
countries that are members of the ICCAT must respect the ban. This
decision is based on results of a report from Swiss-based WWF which stated
that several thousand dolphins and other vulnerable species were being
killed each year in driftnets in the Mediterranean.
According to the study, the Moroccan driftnet fleet of 177 boats is the
most lethal. While fishing for swordfish these boats accidentally capture
between 3000 and 4000 dolphins every year. Striped dolphins and
short-beaked common dolphins are most often caught. According to
estimates, a further 13 000 dolphins are caught around the Straight of
Gibraltar and neighbouring zones. As well as dolphins, these nets also
kill 100 000 blue sharks, shortfin mako sharks and thresher sharks along
with a good number of loggerhead turtles. Along with Morocco, both Italy
and Turkey still possess fleets of 100 driftnet fishing boats each, while
France has a fleet of 75.
Driftnets are several kilometres in length and, as their name suggests,
they drift along with the currents. They are held near the surface or in
intermediate layers of the water column by buoys attached to the upper
line of the net and weights attached along the lower line. Several
industrialized countries have banned this type of fishing gear due to the
devastating effect it has on marine fauna. Bycatch in these nets
represents a major threat to several species of marine mammals world-wide.
According to a study published last June, nearly 310 000 cetaceans
(whales, dolphins and porpoises) and nearly 350 000 pinnipeds (seals
and sea lions) die in fishing gear every year world-wide.
The WWF is very pleased with this decision. It has determined that
driftnet fishing is a non-renewable activity that threatens several
populations of dolphins, sharks and sea turtles in the Mediterranean. The
WWF emphasizes that measures should be taken by authorities to help
Mediterranean fishermen adopt less destructive alternative fishing
methods. [WWF]

A New Species of Rorqual Whale?
Japanese researchers published an article in the journal Nature last
November 20 describing a new species of rorqual whale that they have named
Balaenoptera omurai in honour of Japanese researcher Dr. Hideo
Omura. Their discovery is based on eight specimens that were hunted in the
eastern Indian Ocean and the Solomon Sea in the 1970swhen the ban on
commercial whaling was not yet in placeand on a carcass found on the
shores of an island off Japan in 1998.
At first sight, these nine carcasses resemble small fin whales
(Balaenoptera physalus). They possess the asymmetrical coloration
of the lower jaw typical of fin whales; the left side of the jaw is
visibly darker than the right side. Also, pectoral fin and tail fin
coloration is similar to that of fin whales. However, a more in-depth
analysis of the anatomy and genetics of these nine specimens have enabled
Japanese researchers to group them into a new species. They are
essentially smaller than fin whales12 metres compared to 20 metres
for fin whales. They have on average 200 baleen plates per side, which is
the smallest number of baleen plates of all rorqual whales, and their
skulls possess unique characteristics. Finally, the analysis of the
mitochondrial DNA of the different species of rorqual whales shows them to
be distinct. These same analyses also allowed Japanese researchers to
separate an existing species in two: Brydes whales (Balaenoptera
edeni) become either Edens whale (Balaenoptera edeni) or
Brydes whale (Balaenoptera brydei). This brings the total
number of rorqual whales to eight.
Certain researchers who believe that more rigorous analyses should be
carried out before defining the nine specimens as a new species are
criticizing this discovery. Others believe that to too finely split
species dilutes and harms conservation efforts. Finally, the debate over
scientific whaling is once again raging. Some researchers state that it
contributes to science, while others believe that it could imperil the
survival of endangered species. All populations of rorqual whales
underwent intensive hunting in the XIX and XX centuries. This hunting
decimated several populations, including the North Atlantic blue whale
population, which is still having trouble making a comeback. Could
Omuras whale be one of these species that went unnoticed among the
thousands of whales that were hunted? Or could it be a species that, due
to its life style, managed to avoid the whalers harpoons? [Nature,

The United States Senate Exempts the Defense Department from Two
Environmental Laws
The Bush administration has finally won its case. The Senate has
authorized the American Defense Departments exemption from two
environmental laws: the Marine Mammal Protection Act (MMPA) and the
Endangered Species Act (ESA). The MMPA is the American law that protects
marine mammals in U.S. and international waters from all activity that
could harm them.
This decision comes exactly one year after the U.S. Supreme Court came
down with an injunction to stop the American Navys deployment of low
frequency active sonar (LFA) in the worlds oceans. The judge who
made the ruling was aware of the damage this type of system could
inflict on marine mammals. Last August the same judge ordered the U.S.
Navy to negotiate the use of this sonar with environmental organizations.
One month later the two parties had come to an agreement to limit their
use to Asias East Coast.
This agreement has now been compromised by the Senate decision. The new
legislation accepted by the Senate gives the U.S. Navy the right to test
and use, in American waters and in all oceans of the planet, any
technology that defense secretary Donald Rumsfeld deems necessary for the
training of U.S. troop. This includes low frequency sonar. Thus, the
exemption from the MMPA allows the U.S. Navy to use sonar practically
everywhere. This decision comes one month after a study published in
Nature magazine linked several mass strandings of cetaceans to the use of
low frequency sonar.
One of the main plaintiffs in the controversy surrounding the use of
this type of sonar, the Natural Resources Defense Council (NRDC), deplores
the Senate decision and affirms that this decision compromises existing
marine mammal and endangered species protection in the U.S. under these
two laws. This weakening of environmental laws will facilitate the
authorization of certain scientific studies, such as oceanographic studies
that make use of powerful sound emitting devices. These studies are mostly
used for oil and gas exploration in the marine environment. [Seattle

Orca Captured in Russian Waters: A Sad Success Story
On September 26, 2003, a Russian team from the Utrish Aquarium captured
an orca (killer whale) in Far Eastern Russia, a first for this country.
The capture technique consisted of encircling a family group of orcas
using seine nets. Unfortunately, a young orca died during the operation
when it became trapped in the nets. On October 5, the animal that was
successfully captured, a young female less than five meters in length, was
transported to a facility owned by the Utrish Aquarium near the Black Sea.
She died less than a month after her capture.
For three years, Russian authorities have been issuing permits for the
capture of orcas in their waters to various organizations and individuals.
Ten permits were issued this year, each permit allowed for the capture of
one orca. Up until recently, no attempt had been successful. The death of
the young orca during the operation and that of the female in the first
days of captivity have raised concerns about the methods being
usedencircling using seine netsand conditions in captivity.
Since 1961, 135 orcas have been removed from their natural environment in
different parts of the world. Of these 135 animals, 110 have died, on
average within six years of their capture. Presently, 49 orcas are living
in captivity in 12 marine parks in five countries. This trade is as
lucrative as it is controversial: a wild orca is worth nearly US$1
million!
Conservation groups and researchers are very concerned about the
impacts this type of activity could have on local orca populations. Orcas
that live in Russian waters are not very well known. Those living in Far
Eastern Russia have only been studied since 1999. Up until now, 150 orcas
have been photo-identified by the Far East Russia Orca Project (FEROP).
Researchers do not yet know if the captured female was already on file.
The last capture of an orca took place in Japan in 1997. At the time, the
operation raised such a wave of protest that Japan was forced to abandon
the deal. Researchers working for FEROP and the Whale and Dolphin
Conservation Society, which partially finances FEROP, fear that the
isolated waters of Far East Russia may become an area where capturing
orcas becomes even easier. [WDCS]

Japan Refuses to Import Icelandic Products
At the end of its first whaling season in 14 years Iceland is already
facing serious problems financing its scientific whaling programme through
the sale of whale products. To begin with, the meat has not solicited much
more than a lukewarm response from local consumers. Also, according to a
confidential Whale and Dolphin Conservation Society (WDCS) source, Japan
has refused to import Icelandic whale products. Trade in whale products
was planned, despite the restrictive rules of the Convention on
International Trade in Endangered Species (CITES). Japan is having trouble
selling thousands of tonnes of whale meat and blubber from its own
scientific whaling programmes to Japanese consumers. Although these
products were valued in the past, sales and prices have been falling
steadily in recent years. Changes in consumer preferences and growing
concerns about contaminants in whale meat are at the root of this decline.
As a matter of fact, PCB levels measured in minke whale blubber last May,
had already extinguished any hope Norwegian whalers may have had of
selling their thousands of tonnes of this product to the Japanese.
Various analyses carried out by different researchers on meat samples
from both Japanese and Norwegian markets have revealed that these products
contain alarming levels of contaminants. Powerful toxic
contaminantssuch as PCBs, DDT and other pesticides, along with heavy
metals such as mercuryhave been measured in concentrations that
exceed acceptable limits for human consumption. The disastrous effects of
these products on human health are well documented: nerve damage,
developmental disorders, reproductive disorders, immune system
suppression, cancer, etc. Moreover, several countries that consume whale
and marine mammal products recommend that pregnant and nursing women
refrain from consuming, or reduce consumption of, these products.
After six weeks of whaling in the Northeast Atlantic, Iceland harpooned
36 minke whales, of a quota of 38. Difficulties faced by Iceland in
selling its products will likely compromise planned expansion of its
whaling programme in coming years and limit plans to extend its programme
to include species such as fin whales and sei whales. [WDCS, HSUS,

A Right Whale Dies from a Ship Collision in the Bay of Fundy
A North Atlantic right whale was found dead approximately 40 km off
Digby, Nova Scotia last October 2 by Fisheries and Oceans Canada (DFO)
during a routine patrol. The carcass was then towed to shore by a team
from the Woods Hole Oceanographic Institution (WHOI), the Cape Cod
Stranding Network, the New England Aquarium and DFO, with the help of a
local fishing vessel.
A post-mortem examination, performed by the Atlantic Veterinary College
of Prince Edward Island and East Coast Ecosystems, revealed that the
animal had died one to two weeks earlier after a collision with a ship.
Several bones in the skull were fractured. The whale was a 13.5-m long
female known under the code name #2150. She had been identified for the
first time in 1991 and had given birth to her first and only calf in
2001.
Ship strikes are the cause of 50 percent of deathsexcluding
new-bornsof this species that is threatened with extinction. Less
than 325 North Atlantic right whales remain. In an attempt to reduce the
extent of this problem, shipping lanes in the Bay of Fundy were moved last
July as the result of a concerted effort between Transport Canada,
Fisheries and Oceans Canada, International Maritime Organization along
with several conservation groups and industries that use the shipping
lanes.
The analysis of the drift of the carcass will allow researchers to
determine the place where the accident took place. This information could
be used to adjust measures for the protection of this species in the Bay
of Fundy area. The premature death of breeding females seriously
compromises the species chances of recovery. [Canadian Press]

U.S. Navy Sonar: will its use be restricted?
On the heels of a court judgement in favour of environmental groups,
the U.S. Navy has finally come to an agreement with these groups to limit
the use of its LFA (Low Frequency Active) sonar to Asias eastern
seaboard. This sonar system, created to detect modern submarines, was to
be deployed in over 75 percent of the world's oceans. Now, in addition to
this limited zone, the U.S. Navy must also respect coastal exclusions
ranging from 30 to 60 nautical miles and seasonal limits to protect
certain species during their migration.
This agreement comes as the Pentagon is lobbying Congress for
exemptions to certain provisions of the Marine Mammal Protection Act and
the Endangered Species Act. These exemptions would allow the U.S. Navy to
use low frequency sonar virtually anywhere. They could also lead to
expanded seismic explorationa geophysical data acquisition system
based on the emission of powerful soundsused, among other things,
for oil and gas exploration. At the same time, Republicans are working on
legislation to replace a federal moratorium on gas and oil development
along the U.S. coast.
Several mass stranding events have been associated with the use of low
frequency sonar. One example is the mass stranding of 14 beaked whales in
the Canary Islands in 2002 during international military exercises in this
same area. In a recent issue of Nature, dated last October 9, a team led
by Paul Jepson of the London-based Institute of Zoology revealed that the
deaths of these cetaceans was probably caused by decompression sickness.
This condition comes about when bubbles form in tissues causing serious
damage that can lead to death. Sounds produced by the sonar may drive
cetaceans to rapidly rise to the surface, which would explain the
formation of the bubbles. The bubbles could also be the physical effect of
powerful sounds on the gas nuclei present in the tissues of deep diving
whales.
The use of powerful sounds in the marine environment also raises
serious questions in Canada where there is a strong lobby to conduct
seismic surveys for the exploration of petroleum potential along the
Pacific Coast, in the Gulf of St. Lawrence and along the Atlantic Coast.
An affiliation of Quebec organizations is publishing a press release this
week asking the Québec Premier to suspend oil and gas
exploration activities in the Gulf of St. Lawrence. [Nature, ENN, Yahoo,

Luna to Return Home
On October 1, the Department of Fisheries and Oceans Canada (DFO)
announced its decision to reintroduce Luna, a young, solitary killer whale
presently in Nootka Sound west of Vancouver Island, to its family
group.
Luna, known to researchers by his code name L98, became isolated from
his family group, L-pod, in July of 2001. He has since been swimming the
waters of Nootka Sound on his own. This young, four-year-old male is a
member of the population of 275 resident killer whales present in B.C.
waters. The southern resident killer whale population, which includes
L-pod, has been on the Committee on the Status of Endangered Wildlife in
Canada (COSEWIC) list of endangered species since November 2001.
Researchers do not know how this young whale became separated from his
pod. Since then, however, researchers and other curious humans have been
monitoring the whales unusual behaviour and its state of health.
This year, Luna intensified interactions with humans by more frequently
approaching boats, rubbing against them and occasionally stopping them.
These interactions have caused problems, as much for humans as for the
whale. For example, three fishermen ended up spending a night on the water
when their boat ran out of gas and Luna prevented them from rowing to
shore. Lunas curiosity about boats has also led to at least two
minor injuries: a cut over each eye caused by boat propellers.
In May 2003, DFO decided not to intervene in Lunas case. They
were concerned that any action could affect the animal and its population.
In September 2003, following on the recommendations of the scientific
panel, the Department overturned its decision, taking into account that
Lunas behaviour warranted an intervention as much for public safety
reasons as for the animals welfare. Various Canadian and U.S.
environmental groups have also put a lot of pressure on DFO. The
scientific panel, composed of Canadian and U.S. private and public sector
researchers, considered all possible options, including captivity.
In coming weeks DFO, along with one or several groups or organisations
with the required expertise and financial backing, will undertake the
operation. In 2002, DFO, along with other organisations, successfully
reintroduced a young female killer whale known as Springer (or A73), that
had also become separated from her group. However, attempts to reintroduce
Keiko, the killer whale star of the film "Free Willy" held in
captivity for 25 years, have not met with success. After five years and
millions of dollars invested in the operation, Keiko is still swimming the
waters of a Norwegian fjord, dependent on the care of his
trainers.[Fisheries and Oceans Canada]

Could the predatory activities of killer whales be responsible for the
decline in seal, sea lion and sea otter populations?
A new study conducted by American researchers and published in the
Proceedings of the National Academy of Sciences has revealed that the
decline of seal, sea lion and sea otter populations in the North Pacific
Ocean since the 1970s could be explained by an increase in predatory
activity by killer whales.
Through the analysis of past commercial whaling records, researchers
Alan Springer of the University of Alaska and Jim Estes of the University
of California affirm that the over exploitation of great whales in the
North Pacific between 1946 and 1979 provoked dietary changes in killer
whales. According to their theory, this massive removal deprived certain
killer whales of traditional prey, namely great whales, causing killer
whales to turn towards other species of marine mammals such as seals, sea
lions and sea otters.
The impact of killer whales on sea otter populations had already been
studied and demonstrated by Jim Estes, however the same work had not been
carried out on seals and sea lions. To do this, researchers constructed
models that took into account the energy requirements of killer whales,
the nutritional value of sea lions and sea otters and the number of deaths
necessary to explain the declines already observed. Their results
demonstrated that a slight shift in the diet of the 10 percent of killer
whales of the region that feed on marine mammals could bring about the
documented declines. The effects of this change on the food web go way
beyond the impact on marine mammals. This change could possibly explain
the decimation of kelp forests in Alaska that have been devoured by sea
urchins, a prey species of declining sea otters. Mr. Springer states that
overfishing and massive extraction can lead to unexpected effects on the
food web.
These conclusions have not been universally approved by all
researchers. Andrew Trites of the University of British Columbia argues
that great whales are not a major prey species for killer whales and
likely never have been. On the other hand, he states, porpoises, dolphins
and minke whales are, and these species were ignored by the study. Trites
believes that climatic shifts, leading to changes in fish populations, are
behind the decline of the marine mammals named in the study.

Pristine lakes in Alaska contaminated by spawning salmon
A recent study by Canadian and American researchers has demonstrated
that millions of sockeye salmon spawning in pristine Alaskan lakes are the
cause of high levels of PCBs found in several of these lakes. Jules Blais
of the University of Ottawa, one of the researchers working on the
project, has stated that levels as high as those found in industrialized
areas have been recorded in these distant lakes.
Every summer, in order to spawn, millions of sockeye salmon migrate
from their feeding grounds in the North Pacific towards the lakes where
they were born, carrying with them large doses of PCBs from the Pacific
Ocean. Although PCB emissions have diminished over the past two decades,
large quantities of this contaminant still remain in the Pacific Ocean and
accumulate in the food web. PCBs are produced by the manufacture of
flame-retardants and paints and by the burning of waste.
The problem does not reside in the quantity of PCBs transported by each
salmonthe fish are ediblebut in the effect of bioaccumulation.
Once they have spawned, the salmon die and slowly decompose on the lake
bottom. The carcasses then become food for other organisms that ingest the
contaminants. The contaminants are transmitted and accumulated, from prey
to predator, all the way up the food web. Large quantities of PCBs also
accumulate in the lake sediment. Researchers estimate that lake sediment
where salmon spawn contains PCB concentrations that are as much as seven
times higher than concentrations in lake sediment where salmon do not
spawn. Researchers fear that this phenomenon also affects top carnivores
such as bears, eagles and humans.
Although the Pacific Ocean is viewed by many as a pristine area, the
facts tell a different story. A wide range of contaminants, often traces
of past negligence, can be found in this environment. Another group of
Canadian and American researchers have come together to investigate this
problem. In order to obtain indications on water-borne contaminants they
will be studying the diet of harbour seals. Being predators situated high
up in the food web, these seals will give researchers clues concerning
contaminants that also affect killer whales, which are listed as an
endangered species in Canada. High levels of PCBs have already been noted
in Pacific killer whales, particularly the nomads that are at the top of
the food web and feed on other marine mammals. Fortunately, since PCB
emissions have dropped, lower concentrations are now being measured in
whale calves. [Nature, CBC, Biosphère]

U.S. Navy Sonar: Federal Court Judgement
On August 26, the U.S. Federal Court came down with its final ruling
concerning the deployment of a U.S. Navy sonar system. Last October,
Magistrate Judge Elizabeth Laporte had imposed an injunction to stop the
deployment of the Surveillance Towed Array Sensor System Low Frequency
Active sonar (SURTASS LFA). She has now ordered the U.S. Navy to reduce
potential harm that it could cause to marine mammals and fish by
negotiating limited use of the system (where, when and how) with
conservation groups. In her judgement she also stated that the permit
given to the U.S. Navy by the National Marine Fisheries Service for the
deployment of the system violates several laws such as the Marine Mammal
Protection Act (MMPA), the Endangered Species Act (ESA) and the National
Environmental Policy Act (NEPA).
The U.S. Navy had planned on deploying this system in 75 percent of the
worlds oceans. The loud, low frequency sounds emitted by the SURTASS
LFA can travel thousands of square kilometres, scanning the oceans to
detect submarines. These sounds can reach levels of 240 decibels at their
source, and between 150 and 160 decibels 200 km away. The U.S. Navy has
already confirmed that, at these levels, sound can harm marine mammals.
In March 2000 several species of whales stranded in the Bahamas. An
investigation concluded that the use of medium frequency sonar by
the U.S. Navy in this area was the cause of this event. In September 2002,
several beaked whales died stranded in the Canary Islands as a result of
NATO military exercises. More recently, last May, further exercises
conducted by the U.S. Navy off Vancouver Island appeared to be the likely
cause of the deaths of dozens of harbour porpoises and the erratic
behaviour of a group of killer whales.
The plaintiffs, headed by the National Resources Defence Council
(NRDC), are pleased with the judges decision. The Navy has
stated that it is reviewing the decision, but it is initially concerned
about repercussions on national security. The Bush administration has been
vigorously attacking environmental restrictions that it believes
compromise national security. Several propositions to weaken environmental
laws such as the MMPA are before Congress.

by recognizing their contributions as a "Gift to the Earth".
Over the years these nations have either taken the initiative of declaring
their Exclusive Economic Zones (marine areas within 200 nautical miles of
their coasts) whale sanctuaries or have adopted national legislation to
protect whales. The following nations have thus protected 28 million sq.
km of ocean: the Cook Islands, Fiji, French Polynesia, Niue, New
Caledonia, Papua New Guinea, Samoa, Tonga, Vanuatu, Australia and New
Zealand.
As well as favouring the recovery of certain endangered whale
populations, the creation of these sanctuaries, combined with a good
management plan, should work as a tool for the conservation of the marine
environment and the development of certain activities such as fishing and
ecotourism. Whale watching has been expanding around the world over the
last 10 years. As an industry, it generates more than US$1 billion
annually worldwide. In certain countries it has even replaced whaling, an
activity abandoned by several countries since the adoption of a moratorium
on commercial whaling by members of the International Whaling Commission
(IWC) in 1982.
The IWC has already established two whale sanctuaries: the Indian Ocean
Sanctuary, created in 1979, and the Southern Ocean Sanctuary, created in
1994. For several years now, Australia and New Zealand have been proposing
the creation of a South Pacific Sanctuary (complementary to the Southern
Ocean Sanctuary) to members of the IWC. This proposition has yet to
obtain sufficient votes to be adopted. The WWF has been campaigning
for years to get South Pacific nations to ban whaling within their
territorial waters. This network of sanctuaries could be an alternative to
a sanctuary declared by the IWC. The WWF hopes that the "Gift to the
Earth" award and the publicity surrounding it will incite the other
Pacific islands to imitate the initiatives of these 11 nations. [WWF,

Icelandic Whalers Go Minke Whaling
Three Icelandic boats left port on Sunday to go whaling. When Iceland
rejoined the International Whaling Commission (IWC) in October of 2002 it
clearly stated its desire to recommence commercial whaling after 2006 and
to carry out scientific whaling until then. During the annual meeting of
the IWC in April of 2003, Iceland presented its whaling programme to the
Scientific Committee. The plan proposed taking 100 fin whales, 50 Sei
whales and 100 minke whales in the fall of 2003.
On August 6, Icelands fisheries minister announced a revised
scientific whaling programme. Over the course of their six week mission,
researchers will kill only 38 minke whales from a population estimated at
43 000 by the IWC. According to the minister, this decision demonstrates
Iceland's willingness to be constructive and to compromise when it comes
to whaling issues. Iceland is heavily dependent on marine resources and
the carcasses will mainly be used to study the whales food in order
to evaluate the impact of whales on fish stocks. As for whale products
that can be exploited, they will be sold in local markets as provided for
in the IWC regulation on scientific whaling.
Last Monday, Iceland harpooned its first minke whale of the programme.
This has created a good deal of controversy within the IWC, the various
conservation groups concerned and the country itself. Iceland completely
abandoned whaling in 1989 and several Icelanders have since turned to a
new, flourishing industry: whale watching. This industry now brings in
several million dollars per year, and tour operators are
worried that renewed whaling will compromise their livelihood.
Conservation groups, such as the International Fund for Animal Welfare
(IFAW), the Whale and Dolphin Conservation Society, Greenpeace and the
World Wide Fund for Nature (WWF), are firmly opposed to the resumption of
whaling and are putting pressure on Iceland to abandon its project. The
scientific value of the program is also being questioned.

Whales Victims of a Red Tide?
An unusual number of whale carcasses have been reported off the eastern
Canadian and American coasts. More specifically, the carcasses were in the
Georges Bank area, approximately 150 miles off Cape Cod, Massachusetts.
Over the past month, airplanes and ships have spotted 17 carcasses, mostly
humpback whales and several fin whales.
The alarm was sounded on July 3 when three humpback whales floated at
the surface and were spotted by fishermen who were carrying out an aerial
survey of the area. Other carcasses have been regularly reported, an
unusual number, according to Philip Clapham of the Northeast Fisheries
Science Center in Woods Hole, Massachusetts.
Researchers from Fisheries and Oceans Canada and the Woods Hole
Oceanographic Institution are presently working on the case. They are
taking urine, blood, skin and blubber samples in an effort to discover the
cause of this mass fatality. Several researchers believe that this event
could be caused by a red tide, the blooming of toxic red algae of the
genus Alexandrium.
This type of algae produces toxic substances known as saxitoxins, which
are not toxic to the animals that accumulate them, such as molluscs and
several species of fish. However, they are toxic for mammals. This species
of algae is normally found near the coast, however unusual winds and
currents of recent weeks may have transported these algae offshore and
"infected" mackerel, a fish species on which the whales feed.
Red algae killed 14 whales in this same area in 1987. Mass fatalities
caused by toxic algae are quite rare for whales. However, these events
regularly cause dolphin, sea lion and sea-otter deaths in several areas
around the world, like the coast of California. [Nature News Service,

Difficult to Count the Whales... of the Past!
A study published in the prestigious "Science" magazine on July 23,
2003, reports new North Atlantic whale population estimates before
intensive whaling began. Jo Roman of Harvard University and Steve Palumbi
of Stanford University affirm in their article that estimates based on
whaling ship logs underestimated whale populations at the time.
Roman and Palumbi analyzed the variation of a certain type of DNA
(mitochondrial DNA)from North Atlantic minke whale, fin whale and humpback
whale samples. They noted a large variability of this type of DNA for each
of the species, which suggests that very large populations existed in the
past. They evaluate historic populations of minke whales, fin whales and
humpback whales in the North Atlantic at 265 000, 360 000 and 240 000
respectively.
These new numbers are much greater than estimates used by the IWC
(International Whaling Commission) for decisions related to whaling. Using
numbers based on whalers' records from the middle of the XIX Century, 130
000 minke whales, 40 000 fin whales and 20 000 humpback whales swam the
waters of the North Atlantic before commercial whaling began. Roman and
Palumbi believe that their estimates should replace those used by the
IWC.
This statement has not been unanimously accepted by the scientific
community. Several researchers believe that the technique used is fallible
and that small errors could have drastic effects on results. The IWC
evaluates present-day North Atlantic populations of minke whales, fin
whales and humpback whales at 120 000 to 182 000, 27 000 to 82 000 and 11
570 respectively. Counting living whales is already a difficult task...
imagine counting the whales of the past! [NNS, BBC]

Capture of Live Dolphins in the Solomon Islands
A major capture of live dolphins, the largest to date, has taken place
in recent weeks in the Solomon Islands, an archipelago of over 1000
islands north east of Australia. Parque Nizuc, an aquatic park in Cancun,
Mexico, directed the operation and ordered the capture of several dozen
dolphins (likely as many as 200 of them). Local fishermen earned between
AU$60 to AU$400 (CN$55 to CN$365) per dolphin. The animals were captured
off the islands, transported by boat and kept in an enclosure near the
shore.
As with many countries, Mexican law prohibits the capture of live
cetaceans in Mexican waters. However, this same type of enterprise is not
prohibited in certain countries, like the Solomon Islands, where the
political situation is difficult, indeed chaotic. For many residents,
this type of enterprise is an insult to their culture: according to
ancestral beliefs, some humans have the power to change themselves into
dolphins. Therefore, it is taboo for the islanders to hinder these animals
in any way.
Despite pressure from several environmental groups and the Australian
government to abandon the project, Mexico went forward with the
importation of some thirty dolphins to Parque Nizuc last Monday. The
Mexican government has stated that the aquatic park has all required
authorizations for this type of operation. Several specialists were
worried. They were concerned about the dolphins abilities to endure such a
long voyage on a cargo plane. In fact, representatives of the park and
Mexican environmental groups affirm that the animals, which are presently
being kept in enclosures near the beaches of Cancun, are in good health.
What will happen to these dolphins? Rumour has it that they will be sold
for several thousand dollars each to foreign aquatic parks, a rumour that
has been denied by Parque Nizuc.
The international CITES convention, signed by 160 countries including
Mexico, regulates international trade in endangered plant and animal
species. All cetaceans (whales, dolphins and porpoises) are listed in
Annex 1, which includes endangered species. Trade in these species is
permitted only under exceptional conditions and import and export permits
are required. [The Age, ENN]

Right Whale Conservation Effort Leads to Action
A new conservation measure for North Atlantic right whales has
been in place since July 1. Shipping lanes in the Bay of Fundy have been
changed. This heightened protection is the result of a concerted effort
between Transport Canada, numerous conservation groups, representatives of
industries that use the shipping lane, Fisheries and Oceans Canada and the
Marine Safety Committee of the International Maritime Organization
(IMO).
Acting on recommendations put forward in the North Atlantic Right Whale
Recovery Plan, published in 1998, Transport Canada worked for four years
with the various concerned parties to modify the shipping lanes. In April
of 2002, the ministry submitted its proposal to the IMO. The proposal was
accepted in December 2002.
This is the first time shipping lanes have been altered to protect an
endangered species. There are only 300 to 350 North Atlantic right whales
left. Ship collisions have been responsible for almost half of all deaths
over the past decade. Approximately two-thirds of the population spends
the summer in the Bay of Fundy, a prime feeding ground for this species.
Researchers strongly believe that moving the shipping lanes will reduce
the risk of collisions between ships and right whales. They also hope that
this will encourage the United States to undertake a similar project, thus
reducing the risk of ship strikes throughout this species territory.

Annual Meeting of the IWC: Members
are Divided
Once again this year the annual meeting of the IWC (International
Whaling Commission) ended in discord. The meeting was held from June 16 to
19 in Berlin, Germany. Pro and anti-whaling nations were not able to come
to a common agreement.
Although it was created in 1946 to improve the management of commercial
whaling activities, several resolutions adopted by the Commission since
the moratorium was announced in 1982 have taken on
"conservationist" overtones. This has led to the frustration of
whaling nations such as Japan, Norway and Iceland that are unable to
obtain satisfaction. Japan has threatened to withdraw from the Commission
after members adopted a resolution to create a Conservation Committee.
This Committee would have the mandate to evaluate problems faced by
cetaceans, such as accidental entanglement in fishing gear, ship strikes,
contamination and climate change.
Whaling nations also presented their scientific whaling programmes
during the meeting. Japan proposes to broaden its annual hunt of 400 minke
whales in the Antarctic and maintain its hunt in the western North
Pacific. The latter programme involves the killing of 150 minke whales, 50
Brydes whales, 50 sei whales and 10 sperm whales to study the
feeding ecology of these cetaceans. Iceland presented a similar scientific
whaling programme with the killing of 100 minke whales, 100 fin whales and
50 sei whales. Considering the value of this scientific hunt, the
possibility of using non-lethal methods to study the same questions,
uncertainty surrounding the evaluation of whale populations and a possible
hidden agenda for commercial whaling, the Commission adopted a resolution,
by a slight majority, encouraging whaling countries to abandon their
scientific whaling programmes.
Once again, propositions for the creation of sanctuaries for the whales
of the South Pacific and the South Atlantic failed to gain the necessary
three-quarters majorities to be adopted, although they did obtain a
majority of the votes. As for the Revised Management Scheme to control
commercial whaling activities in the event of a lifting of the moratorium,
it has yet to be completed; though the Commission maintains that the work
is ongoing.
Finally, it was during this meeting that subsistence-whaling quotas for
aboriginal communities in the United States, Greenland, Russia and St.
Vincent and the Grenadines were established. It is worth noting that
Canada withdrew from the IWC in 1982 when the moratorium was first
announced. However, the subsistence whaling of narwhals, belugas
and bowhead whales still takes place in Canadian Arctic waters. [IWC]

Thousands of Marine Mammals Die Every Year, Victims of Entanglement in
Fishing Gear
A new study published by researchers Andy Read of Duke University,
U.S.A. and Simon Northridge of the University of St. Andrews in the United
Kingdom is the first to give worldwide estimates of marine mammal
by-catch. Basing their numbers on marine mammal by-catch in U.S. fisheries
between 1990 and 1999, the researchers estimate that approximately
308 000 cetaceans (whales, dolphins and porpoises) and 345 000
pinnipeds (seals and sea-lions) die in fishnets every year. During this
period, 84 percent of by-catches of cetaceans and 98 percent of by-catches
of pinnipeds occurred in gill net fisheries.
The publication of this study coincides with the annual meeting of the
International Whaling Commission (IWC), which is taking place this week in
Berlin, Germany. Members of the World Wide Fund for Nature (WWF) hope this
study will pressure the IWC into passing a resolution to make the by-catch
problem a priority issue.
The researchers affirm that this level of by-catch seriously threatens
several cetacean populations. More than half of all North Atlantic right
whalesa species reduced to less than 350 individual
animalsbear wounds or scars caused by fishing gear. In the
Gulf of Mexico, 15 percent of a population of small cetaceans known as
vaquitas die each year in fishing nets. Only 500 individuals of this
species remain. Entanglement in fishing nets is responsible for the
decimation of the Irrawaddy dolphin in the Philippines. Less than 70
individuals remain.
Cetacean by-catch in the United States dropped by two thirds at
the end of the 1990s, while numbers for pinniped by-catch remained
unchanged. This reduction for cetaceans is attributed to the application
of conservation measures aimed at reducing by-catch. However, a reduced
fishing effort in certain areas is also responsible for the decline. The
WWF recognizes that the solution to this problem is dependant on the
co-operation and creativity of fishermen as well as the willingness of
governments to solve it by increasing research funds for the development
of fishing gear that poses less of a threat to marine mammals.[WWF]

Fisheries and Oceans Canada to Regulate Whale-Watching Activities
The last of a series of meetings organized by Fisheries and Oceans
Canada took place on June 4 in Les Escoumins. These nation-wide public
consultation meetings were held in light of DFOs project to modify
its Marine Mammal Regulations. The existing Marine Mammal Regulations
prohibit the disturbance of marine mammals (whales, seals and sea
otters). These Regulations are too general and do not
inform the public about behaviours that are unacceptable when viewing
marine mammals in their natural environment. Whereas cruises aimed at
viewing whales and other marine mammals are increasingly popular in
Canada, a report by Dr. Jon Lien of Memorial University in Newfoundland
has demonstrated that these activities can adversely affect their
behaviour, and by doing so, prevent them from completing activities that
are essential to their survival.
Proposed modifications to the Regulations include general
considerations such as prohibiting the disturbance of the vital life
processes of marine mammals and prohibiting feeding, touching, swimming
with or displacing marine mammals. Fisheries and Oceans Canada also plans
on introducing measures to manage marine mammal viewing, rescue, research
and media and film production activities.
These Regulations will be applied wherever marine mammals are present
in Canada, be it the Atlantic Ocean, the St. Lawrence, the Pacific Ocean
or the Arctic Ocean. Conditions indicated on permits issued within the
context of these regulations will take regional differences into
consideration. The Marine Activities in the SaguenaySt. Lawrence
Marine Park Regulations that have been in place since 2002 will still
apply. Fisheries and Oceans Canadas new Regulations will harmonize
the behaviour of operators working on the periphery of the Marine Park
with the Regulations that are in place within the Park.
The general public has until mid-August to forward comments,
suggestions or advice to Fisheries and Oceans Canada. To obtain a
workbook, visit Fisheries and Oceans Canadas website. The results of
these public consultations will be compiled as of September, after which
DFO will work on the writing of proposed amended Regulations. These
proposed Regulations will be presented to the general public in the spring
of 2004, before the parliamentary process begins. [Fisheries and Oceans

U.S. Navy Military Exercises in Canadian Waters
The U.S.S. Shoup, a U.S. Navy destroyer, is the cause of a major
controversy that has been brought to light by the media, biologists and
environmentalists from both the Canadian and American West Coast. While en
route to the Canadian Forces Nanoose Bay test range, the
destroyers crew carried out submarine detection and avoidance
exercises using a very powerful (over 200 dB), mid-frequency (3 kHz)
sonar for 5 hours in an area frequented by several cetaceans.
Researchers and people working for whale-watching companies in the area
around Haro Straight and San Juan Straight near Vancouver Island heard
these powerful sounds through hydrophones, as well as at the surface
without special equipment. Around twenty killer whales, part of an
endangered resident population, along with hundreds of porpoises and a
minke whale, were also present. According to observers, these cetaceans
appear
to have strongly reacted to the sound. The killer whales first grouped
together
near the shore then split up, changing direction on several occasions and
displaying unusual diving behaviour. As for the porpoises and the minke
whale, they left the area in a hurry.
Several porpoises were found dead in the same area one week after these
events. There is concern that the use of sonar may be to blame for the
demise of these animals. Carcass examinations will be carried out
to determine cause of death. It is important to note the occurrence of
several other similar events in the past, such as an incident in the
Bahamas in March 2000. The American Navy admitted that the sonar tactics
it was testing could have been the cause of the stranding of seventeen
cetaceans found at the time.
There is no law prohibiting the use of sonar in this area, although the
Canadian Navy shuts down sonar when marine mammals are present on the
Nanoose Bay range. As for the Americans, the Pentagon is seeking to exempt
the Secretary of Defence from several environmental laws in order to allow
the U.S. Navy to test low frequency (LFA) sonar. For now, the U.S. Navy
holds a permit from the National Marine Fisheries Service (NMFS) that
allows them to harass, harm or kill marine mammals.[CBC, Vancouver
Aquarium]
This just in: On February 11, 2004, scientists charged with the
examination of 14 harbour porpoises found dead in Puget Sound in the summer
of 2003 have announced the results of the necropsies. Given the advanced
state of decomposition of the carcasses, the scientists were not able to
determine the cause of death for five of them. Three porpoises likely died
from ship strikes or a collision with another animal, while two others died
of a bacteriological infection and pneumonia. Even though they discovered
signs of disease and injury in the ears of several of the porpoises, the
scientists were not able to determine if these were caused by sonar or
other means, such as decomposition.[Vancouver Aquarium]

A Good Year for California Grey Whale Recruitment
Grey whale numbers along the California coast indicates a good birth
rate this year. These whales are presently leaving their mating grounds
off the Mexican coast to head towards their feeding grounds in Alaskan
waters. Over the past decade researchers had noted an increase in deaths
and major fluctuations in the birth rate of this population. In 1998, 1388
calves were counted, compared to 427 in 1999, 279 in 2000 and 256 in 2001.
In 2002, 850 females with calves were counted and researchers are
confident the California grey whale birth rate will be similar this
year.
The California grey whale population came close to extinction due to
intensive whaling in the 1800s. In 1969, this species was added to the
American list of endangered species. In 1994, after years of conservation
efforts and scientific monitoring, the population was taken off of the
list. Four years later, the population was estimated at 26 000
individuals! Last year, however, the population was re-evaluated at
17 000 individuals.
Researchers have recently become concerned about fluctuations and the
low birth rate noted over several consecutive years. Some researchers
suggest that the Eastern Pacific has reached the limit of its ability to
sustain this whale species, which would explain the end to population
growth. On the other hand, National Oceanographic and Atmospheric
Administration biologist and California grey whale specialist, Wayne
Perryman, maintains that this population is feeling the effects of changes
in oceanographic conditions. Mr. Perryman attributes the years of low
birth rates to extensive ice cover present in the Arctic when the grey
whales reach this region. He also affirms that the successful birth of a
California grey whale depends on how fat the mother is. This is related to
the accessibility of prey over the course of the summer, which is in turn
related to the amount of ice present in the Arctic during this same
period. An underfed female could terminate its pregnancy instead of
carrying a foetus that it could not bring to term. This would explain the
low birth rates of 1999, 2000 and 2001. Mr. Perryman adds that global
warming, while not in itself a good thing, could be beneficial to the
California grey whales as it would free the Arctic of its ice more
quickly. [Santa Cruz Sentinel]

Scientific Whaling: Science or Smokescreen?
Phil Clapham and his colleagues, all members of the Scientific
Committee of the International Whaling Commission (IWC) published an
article in the March edition of BioScience that seriously criticized the
scientific whaling programme carried out by Japan since the establishment
of the whaling moratorium in 1986. They maintain that this programme does
not include testable hypotheses or other performance measures, that the
data collected are not necessary for the management of whale populations,
that the data are not submitted to an independent review, that more useful
information can be gathered without killing the animals and that this
programme sacrifices more whales than would be permitted by IWC quotas if
there were not a moratorium.
This article is part of a debate that began last year, in May 2002,
when 21 scientists published an open letter addressed to the Japanese
government in the New York Times in which they urged Japan to suspend its
scientific whaling programme. William Aron and two of his colleagues
responded to this letter in an article published in BioScience. They
stated that the scientists that signed the letter to the New York Times
were more motivated by their personal opinions than by scientific fact.
Thus, the article written by Clapham and his colleagues reconfirms the
credibility of the authors of the New York Times letter by supporting the
critical arguments that they summarized. Moreover, Clapham and his
colleagues point out that Japans scientific whaling programme is
being used to fulfil commercial objectives.
Japan annually hunts approximately 700 whales within the context of its
scientific whaling programme. Recently, Japanese whalers returned from
Antarctica with approximately 440 minke whales. They will now be
proceeding with the other part of the scientific whaling programme. First,
they will spend 40 days along the countrys northeast coast to hunt
50 minke whales. Then, in May, the fleet will depart for three months of
whaling in the eastern North Pacific to kill 100 more minke whales, 50
Brydes whales, 50 sei whales and 10 sperm whales.
Norway also hunts around 700 minke whales each year in the North
Atlantic. This is a commercial hunt. Norway objected to the moratorium and
is therefore not bound by it.
Iceland recently rejoined the IWC making its objection to the whaling
ban, a condition of its membership. Iceland wants to resume
commercial whaling by 2006. Until then, scientific whaling is being
discussed, with proposed annual takes of 100 fin whales, 50 sei whales and
100 minke whales. International conservation organizations are opposed to
this project, as is Icelands tourist industry, specifically its
whale-watching sector. [Clapham et al. 2003, Briand et al.

Iceland Announces its Proposal to Begin Scientific Whaling
Last week Iceland submitted its proposal to the International Whaling
Commission (IWC) to begin scientific whaling. According to the plan
Iceland will hunt 100 fin whales, 50 sei whales and 100 minke whales
annually. The fin whale and the sei whale have both been designated as
endangered by the IUCN (World Conservation Union).
Those in favour of the scientific hunt justify their support by stating
that the research aims to investigate cetacean diets, distribution and
numbers. These arguments are the same as those put forward by Japan, which
hunts several hundred minke whales per year. However, those who are
against the hunt claim that information concerning all of these subjects
can be collected without killing whales. Japanese market interest for
Icelandic whale products played an important role in the decision to
resume whaling.
Conservation groups, like the World Wildlife Fund (WWF), condemn the
project. The Whale and Dolphin Conservation Society is concerned about the
effects this hunt may have on Icelands whale-watching industry.
Greenpeace warns that whale populations are just beginning to recover from
years of exploitation, breed slowly and are jeopordized by other human
threats such as pollution and climate change.
The next IWC meeting will be held in Berlin, Germany in June of 2003.
