This winter brought good news for
the northern right whale, Georgia's official marine mammal and one of
the earth's most endangered creatures. There were 26 births of these baby
behemoths, which can measure 15 feet long and weigh up to one ton. They
were born off the Georgia and north Florida coasts, the only known calving
grounds for right whales. This "baby boom" represents a dramatic improvement
over last year, when only one baby was seen all season. This increase
was especially noteworthy as there are only about 300 of these mammals
worldwide.
Scientists attribute the bumper crop of baby right whales to an increased
supply of the plankton on which the mammoth mammals feed. There may be
even more whale births next year because of increasing plankton levels,
scientists predict.
Unfortunately, deaths greatly outnumber births of these creatures, which
can grow up to 100 tons. One of the two main causes of death is collision
with large ships. Several state and federal agencies have developed an
early warning system to alert ships to the presence of right whales. Navy
and Coast Guard crews from Savannah to Fort Pierce, Florida, are helping
implement this system. Every 12 hours, the Navy issues a report to military
and commercial ships showing the position of all known whales. The Georgia
Conservancy has played a role in improved whale protection in Georgia.
New regulations will help protect right whales from the other great threat
to their survival: entanglements with fishing gear. The National Marine
Fisheries Service now require lobster and gill net fishermen to use equipment
designed to break away at a certain pressure so whales do not get caught
in fishing lines.
