Right
Whales - Bay of Fundy
Distinctive Features of North Atlantic Right Whales:
 Status:
The
North Atlantic right whale (Eubalaena glacialis) is the rarest of
the large whales in the world. Current estimates indicate that no more
than 350 survive along the east coast of North America. Sightings
have been reported from the Gulf of Mexico to Iceland, but most of the
population now is distributed between Nova Scotia and Florida. Major concentrations
of right whales have been documented in the Bay of Fundy and in Roseway
Basin (between Browns and Baccaro Banks on the southern Scotian Shelf)
from early summer to late autumn.
This
whale was given its name by the whalers who considered it the 'right whale'
to hunt because these whales were relatively easy to approach and floated
after death. Right whales were hunted to very low numbers by the late 1800s
and although protected from commercial whaling since 1935, the population
has not recovered. One factor is right whale mortality resulting from collisions
with ships. Right whales are slow swimmers, seldom moving faster than 3-5
knots. They may stay submerged for 15 to 20 minutes when feeding on plankton.
Because a right whale or group of right whales frequently spend periods
lying at the surface, they are vulnerable to collisions with ships.
Ships
operating in the right whale conservation areas
in the Bay of Fundy and Roseway Basin should ask all watches to keep a
lookout for right whales. During night-time and other periods of reduce
visibility, vessel operators should use the slowest safe speed to reduce
the risk of collision with right whales. Despite all precautions, collisions
may still occur. Please report all sightings and collisions to the appropriate
authority listed inside. The information you provide is important in monitoring
the population and will be held in confidence. Thank you for your cooperation.
The
North Atlantic right whale is protected from disturbance and injury by
the Marine Mammal Regulations of the Fisheries Act (R.S.C., 1985, c.F.-14.
Amended 1993) which prohibits the disturbance of marine mammals. Disturbance
includes repeated attempts to pursue, disperse and herd whales and any
repeated intentional act of negligence resulting in the disruption of their
normal behaviour. Disturbing right whales could change and interfere with
their behaviour, force them away from their habitat at critical times and
may cause them injury.
Right
Whale Identification: Right whales
are the most endangered baleen whale. The western North Atlantic right
whale identification project operates each year in the Bay of Fundy from
August through early October, coordinated by the New England Aquarium (NEA),
Boston, MA. NEA have a field station in Lubec, ME, and travel to the Grand
Manan Basin by boat each day the weather is fit. The Grand Manan Basin
is an area of deep water between Grand Manan Island and Nova Scotia. The
project has operated continuously since 1980 in the Bay, the same year
right whales were officially recognized as summer residents. Earlier sightings
in the 1970s were discounted because of the extremely low numbers of right
whales believed to be left in the North Atlantic, but the 1980 sightings
confirmed the presence of right whales in the Bay of Fundy. The primary
surveys were August through early October since this was the most reliable
time when right whales could be found in the Bay. In conjuction, surveys
were also conducted in the Roseway Basin
area off the coast of Nova Scotia. However, since about 1992, right whales
now  arrive
in the Bay as early as June and stay until late November and into December,
with as many as two thirds of the western North Atlantic population visiting
in a season. Few right whales now occur in the Roseway Basin area. To cover
the times when the New England Aquarium crew is unavailable, photographs
have been taken from whale watch vessels (from both Grand Manan and Nova
Scotia) as early as the beginning of June. Recently aerial surveys have
been conducted by East Coast Ecosytems in the late fall and early winter.
To cover the cost of film used by our researchers aboard whale watch vessels,
some of the financial contributions to the GMWSRS Whale
Conservation Fund are being used.
Right whales can be individually identified by craggy, cornified patches on their heads called callosities, located where we have facial hair - chin, eyebrows and moustache. Each whale has a unique pattern of callosities. As well, scars and other markings may help in the identification. While the callosities may change slightly over the years, callosities are a reliable feature for identification. Over 350 individual right whales have been identified in the western North Atlantic - unfortunately this probably represents the entire population. New born calves born in Georgia/Florida waters, can not be identified by callosities because the patches have not yet developed. The Bay of Fundy is one of the nurseries for right whale calves. By the time the calves and mothers arrive in the Bay, the callosity patterns have developed. Photographing the calves in the summer is critical to their continued individual identification and identifying their maternal relationship. In 2000 right whale catalogues were provided to all of the whale watching companies on Grand Manan, funded by the Whale Conservation Fund. In 2003, digital versions of the catalogue was distributed to the above plus the local community school, Grand Manan Museum and Visitor Informaiton Centre.
