Whales Clustering Off Rhode Island May Be After Fish
PROVIDENCE, R.I. — An unusual number of whales in the waters off Rhode Island this year may simply be following their favorite fish, scientists said.
Humpback whales, which for 10 years have clustered around Steelwagen Bank 13 miles north of Cape Cod, are being sighted off Block Island in increasing numbers.
“Now, it’s pretty tough to find a humpback north of Chatham (Mass.),†said Michael Payne, research biologist with the Manomet Bird Observatory in Plymouth, which is studying the distribution of whales for the National Marine Fisheries Service.
Favorite Food
One reason may be the changing distribution of the sand lance, a fish that is the humpbacks’ favorite food, said Howard Winn, oceanography professor at the University of Rhode Island.
There may not have been enough food off Cape Cod to support the burgeoning sand lance population, so the fish migrated to the waters southeast of Rhode Island, Winn said.
Last year, there were 200 to 300 animals; this summer, there are more than 800, said Judy Raab, the administrative director of the Okeanos Ocean Research Foundation of Long Island, N.Y.
The number of humpbacks in the Gulf of Maine has also increased, from about 200 in 1981 to 325 in 1986, said Steven Katona, biology professor at the College of the Atlantic in Bar Harbor, Me.
