North
Atlantic Right Whales
Eubalaena glacialis - The Problem
-
Right whales were hunted to
near extinction.

-
Commercial hunting began hundreds
of years ago
-
Blubber & baleen were valuable
commodities
-
Protection from whaling has
not resulted in increased numbers of North Atlantic right whales.
Their population hovers between 300-350 individuals.
Canadian
Context
Right whales occur in many
areas along the eastern coast during the summer & fall, with the Bay
of Fundy being a primary nursery and feeding area. The Canadian Right Whale
Recovery Plan was developed to address issues specific to right whales
and recommend actions to promote the recovery of these whales.
Canadian
North Atlantic Right Whale Recovery Plan: The
Right Whale Recovery Plan was a joint effort of Fisheries and Oceans Canada,
World Wildlife Fund Canada, biologists, shipping interests including the
Canadian Coast Guard, fishing groups, whale watchers and conservationists.
Team members acted as individuals with specific expertise, and not necessarily
as representatives of their departments, agencies, or organizations.
The
mandate of the Canadian Right Whale Recovery Team was to develop a strategy
and appropriate recommendations for promoting the recovery of right whales
in the western North Atlantic, to a point at which the population is no
longer endangered. In pursuing this mandate, the Recovery Team endeavoured
to:
1.
Evaluate the current status of the right whale population in the western
North Atlantic;
2.
Identify known and potential threats and limiting factors impeding population
recovery; and
3.
Find ways of reducing or eliminating those threats that are related to
human activities.
In September 2000, the Right
Whale Recovery Plan was officially launched and the Right Whale Implementation
Team was formed and met for the first time to begin the process of implementing
the recommendations of the Plan. Our managing director, Laurie Murison,
was part of the Recovery Plan Team and was also works on the Implementation
Team.
Right
Whale Characteristics
Challenges
to Recovery
Recovery of right whales
is contingent on protecting their habitat and preventing accidental deaths.
Elements to consider:
-
Incidental deaths (ship strikes
& entanglement)
-
Habitat changes
-
Toxins & pollutants
-
Genetic bottlenecking
-
Ship Strike

Shipping
Because right whales are
slow swimming, difficult to see, rest at the surface, engage in surface
social behaviour, react at the last minute to approaching vessels, they
are vulnerable to being hit. Photo: Laurie Murison
Possible Remedies
Moving shipping lanes. Right
whales in the Bay of Fundy often occur in the outbound shipping lanes from
the port of Saint John, New Brunswick. Through the efforts of all stakeholders,
the shipping lanes were successfully redesigned to reduce potential overlap
with right whales by 80%. This is the first time shipping lanes have been
moved because of an endangered species.

Caution Mariners: Please avoid collisions with Right Whales!
The
North Atlantic right whale is the most endangered large whale in the world.
Right whales are present in the waters of Atlantic Canada from June to
December. Treat right whales as you would another ship - please steer
clear of whales to avoid collision. Do not expect right whales to
get out of the way. They are not aware of ships.
Right Whale Conservation
Area #1:Grand Manan Basin, Bay of Fundy. This area is important to
the right whales for feeding and is where mothers bring their calves. Threats:

Guidelines (in effect June-December):Avoid these areas if possible.
Due to the location of the eastern portion of Area#1 in the main shipping
channel to Saint John, New Brunswick, this may not be feasible. Area #2
can easily be by-passed to the north or to the south.2. If the area cannot
be avoided, decrease vessel speed, post a lookout and steer ship around
any right whale activity.3. If a right whale is sighted or a collision
occurs, please report the position (in latitude and longitude) to the Department
of Fisheries and oceans via Canadian coast Guard Radio Station, or fax
at (902) 426-8003 or via Fundy Traffic Control (VHF channel 14).
Entanglement
Right whales are very susceptible
to entanglement in fixed fishing gear such as gill nets or lobster traps
mainly because of how they feed - with their mouth open, skim-feeding.
The entanglement is often in the mouth, and around the flipper, body or
tail. Severe entanglement can result in immediate death from drowning,
infection, exhaustion, vulnerability to further entanglement, increased
susceptibility to ship strike, inability to feed - all leading to death.
Disentangling
- Temporary Solution
-
Until solutions can be found
to prevent right whales from becoming entangled in fishing gear, teams
trained
to disentangled whales attempt to free whales from gear. This is
dangerous and not always effective. Even when a whale is disentangled it
can die from infection.
-
Whale
Disentanglement Network: In the Bay of
Fundy the team is primarily focused on right whales but can disentangle
other species as the need arises. This is a co-operative program
with a number of groups including the Department of Fisheries and Oceans,
New Brunswick Department of Fisheries and Aquaculture, East Coast Ecosystems,
New England Aquarium, Center for Coastal Studies, local whale watch companies,
interested residents and the GMWSRS. The Department of Fisheries
and Oceans and Environment Canada Habitat Stewardship Program provided
funds for equipment purchased to establish a full cache of disentanglement
equipment (located at Westport, Brier Island, NS), and first responder
kits on Grand Manan and Campobello Island. To report entangled
whale in Canada call the toll free Environmental Emergency number 1-800
565 1633.
-
If you encounter an entangled
whale it is best to leave it alone but if possible stay within sight of
the animal, ideally until another vessel can take your place. Do
not attempt to disentangle the whale. Please contact the Department
of Fisheries and Oceans through Canadian Coast Guard Fundy Radio, VHF Channel
16, or by calling the Environmental Emergency number 1-800-565-1633.
Any photo-documentation may also be helpful.
You may be asked the following
questions:
What kind of whale is it
and if you are with the whale, what is your location? If not, when
and where did you last see the whale? Is the whale anchored? If not,
what direction was it traveling? Can you see lines or gear? If so
describe the gear (rope, floats, buoys, etc.) Where is the gear? Flippers,
body, tail stock, mouth, over the head, etc. Is the whale able to breath?Are
there any other vessels in the area? This is particularly important
if you can not standby the whale.
Other Solutions
-
Industry involvement with modifying
and changing fishing gear
-
Reducing the number of vertical
lines
-
Changing fishing seasons to
prevent overlap with whales
-
Temporarily removing gear when
whales are present
-
Standing by gear
-
Education & research
Entrapment
Another interaction with
fishing gear can lead to entrapment in fixed fishing traps such as herring
weirs. Right whales are not usually entangled in gear but are free swimming
in the trap. Efforts by the trap operator can free the whale without injury.

Habitat
Changes
Right whales live along
highly industrialized and busy coastlines. Contaminants and other pollutants
are becoming persistent. Drugs and hormone mimicking chemicals are regularly
discharged into ocean water. Coastal waters are becoming increasingly nutrient
rich promoting toxic blooms. Species composition are changing. Climate
change is affecting water temperature and current patterns. Any efforts
to protect and restore local environments will ultimately also benefit
the oceans. Photo: Laurie Murison
-
Reduce and prevent discharge
of excess nutrients & toxic chemicals - i.e. proper sewage treatment,
proper disposal of chemicals
-
Reduce airborne pollution
-
Prevent global warming
-
Remember the 3 R’s - reduce,
reuse, recycle
Habitat Changes: Disturbance
Noise levels have increased
with more ship traffic, blasting, seismic exploration and other activities.
Acoustic deterrents for other species are increasingly used. Right whales
are repeatedly approached by whale watchers & researchers.
-
Establish guidelines of what
are acceptable noise levels & disturbance
-
Develop whale
watch regulations promoting cautious, respectful behaviour towards
right whales.
In the U.S.:
a permit is required to approach a right whale closer than 500 yards (460
m), thus eliminating any right whale watching.
In Canada: Whale
watchers have developed a Code of Ethics to reduce disturbance to right
whales. Whale watching regulations & licensing are being developed.
-
Monitor research activities
to limit potential, persistent disturbance & harmful activities
Habitat Changes: Inadequate
Food Resources
Overfishing has changed
species composition, resulting in changes in competition & prey availability.
Destruction of the ozone layer can reduce phytoplankton a critical component
of the ecosystem. Too many nutrients can promote growth of toxic phytoplankton.
-
Establish & maintain management
practices that protect & enhance the marine environment
-
Prevent overfishing & carefully
consider “new” fisheries
Habitat Changes: Catastrophic
Events
Oil spills are extremely
destructive to the marine environment. Only limited information is available
as to the effects on right whales. Other toxic chemicals are also transported
over water or can enter from land spills. In the Bay of Fundy, local groups,
industry and government agencies regularly meet to develop contingency
planning, train volunteers and educate the public in the event of a disaster.
More information is needed to properly understand how to protect marine
mammals, and in particular right whales. Proper disposal & treatment
of petroleum products can help.
Low
Genetic Diversity
Right whale populations
were severely reduced leading to low genetic diversity
This can lead to increased
inbreeding, resulting in low reproductive rates, lower calf survival
lowered disease resistance.
Some animal populations have recovered from similar situations. Intervention
is not possible but protecting right whales from incidental mortality is
crucial. Photo Laurie Murison

What
happens if a dead right whale is found?
Dead whales can be scientifically
examined and the data obtained used to determine how the whale lived and
died. If the carcass can be recovered, a team will attempt a dissection
or necropsy. Even though right whales were heavily hunted, little is known
about them. Valuable information can be learned including cause of death.
A growing number of museums have added skeletons to their collections to
preserve & display.
New
Brunswick Stranding Network: Live,
mass strandings of toothed cetaceans are not common in the Bay of Fundy.
Most stranded whales are ones that have died at sea and drifted ashore.
We have investigated the establishment of a New Brunswick Stranding Network
as a co-operative program with a number of New Brunswick organizations
including the New Brunswick Museum, Maritime Atlantic Wildlife, Federation
of New Brunswick Naturalists, New Brunswick Department of Fisheries and
Aquaculture, Department of Fisheries and Oceans, Department of the Environment
and other interested groups and individuals. Funding in 2000 from
the New Brunswick Environmental Trust Fund allowed us to research the feasibility
of such a network. Much more work needs to be done to have a fully
functional stranding network. To report a stranding event in
the Bay of Fundy, call the toll free Environmental Emergency number 1-800
565 1633.
Role of
Research
Even basic biology about
right whales is lacking in many cases
Directed research can help
with specific problems as well as generating new information
Long term research is essential
to learn about a long-lived species
North
Atlantic Right Whale Consortium: The
North Atlantic Right Whale Consortium (NARWC) began as a group of
researchers studying North Atlantic right whales. The group now includes
any who are interested in right whale research and meets annually in the
fall at the New England Aquarium in Boston, Massachusetts, USA and more
recently the New Bedford Whaling Museum in New Bedford, MA. Our managing
director, Laurie Murison, is on the board of the NARWC. A website
has been developed www.rightwhaleweb.org.
Summary
-
North Atlantic right whales
are highly endangered
-
By our mere existence, humans
threaten the survival of right whales
-
Ship strikes & entanglement
in fishing gear are recognized as leading causes of death
-
However, it is equally important
to protect right whale habitat - which means preserving oceans from radical
changes
