North Atlantic Right Whale

Saturday marked the end of lobster fishing and the beginning of relative safety for critically endangered right whales in Cape Cod Bay.

From Feb. 1 to April 30,  no trap/pot gear or vertical lines are allowed in an area of over 3,000 square miles to protect North Atlantic right whales whose population has dwindled to around 400. 

Federal regulators are delaying the release of long-awaited regulations designed to protect the critically endangered North Atlantic right whale. 

The proposed regulations would push lobstermen throughout much of the Gulf of Maine to reduce their buoy lines, which have caused fatal entanglements for the whales. They were were expected to be issued by early 2020.  

A group of international scientists are evaluating a new software tool that could help reduce the number of North Atlantic Right Whales dying from entanglement in rope and fishing gear. The tool weighs the relative risk of entanglement at different times of year, and in different places, against mitigation efforts.  

North Atlantic right whale conservationists have ended up exactly where they didn’t want to be – in an escalating battle between lobstermen and scientists.

More than a dozen scientists have signed a letter defending the science behind proposed measures to protect North Atlantic right whales. There are only about 400 of the critically endangered whales remaining, and their numbers are falling.

The carcass of a critically endangered North Atlantic right whale was found off the coast of Long Island, New York on Tuesday, bringing the 2019 death toll to nine.

Announced by the National Oceanic and Atmospheric Administration (NOAA), it's the first documented carcass found in U.S. waters this year, with the remainder discovered in Canadian waters.

The effort to protect endangered whales is taking federal officials on a listening tour from Maine, to Rhode Island, and Wednesday night, to Bourne, where nearly 200 people gathered in a high school cafeteria.

Eight critically endangered North Atlantic right whales have died this summer, several of them hit by ships.

In the last two years alone, 20 North Atlantic right whales have been found dead in Canadian waters. Of the 11 that could be studied, seven were found to have died as a result of vessel strikes.

That has prompted Canada's Department of Fisheries and Oceans to announce a new round of funding to develop better ways for ships to find whales and avoid hitting them. 

One of those technologies is thermal infrared imaging.

At the Center for Coastal Studies in Provincetown, Christy Hudak, a researcher in the Right Whale Ecology Program, leaned over a microscope looking at a water sample, counting and categorizing different kinds of plankton.  

“Right whales love specific type of plankton, which are called copepods. They are more of a tiny  crustacean plankton—think of crabs, or shrimp,” Hudak said. 

In the last month, eight North Atlantic right whales have been found dead in Canada’s Gulf of St. Lawrence, including two members of the critically endangered species this past week.  

Canadian authorities say work to determine these new whales' cause of death is ongoing.

Whatever the cause of these latest deaths, researchers worry collisions with ships are increasingly to blame.

Five North Atlantic right whales have been found dead in the past week – six this month. With just over four hundred individuals remaining, and calving rates low, that’s a death toll the critically endangered population can’t afford.

“Panicking seems appropriate, yes,” said Peter Corkeron, who leads the large whale research program at NOAA’s Northeast Fisheries Science Center.

North Atlantic right whales are critically endangered, with just over 400 individuals left, and their numbers declining. The leading causes of death are well-known: right whales are susceptible to being struck by ships, and over 83 percent have shown evidence of being entangled in fishing gear at one point or another.

But the population has also seen low reproductive rates and declining health status in recent years that can't necessarily be explained by those impacts. Now, new research points to another possible culprit: climate change.
