It's Likely There Aren't More Than 411 Right Whales Left, New Estimate Finds

The latest population estimate for the endangered North Atlantic right whale indicates the species’ recent decline has quickened — with some 30 fewer animals alive by the end of last year than there were at the end of 2016.

An updated estimate by National Oceanographic and Atmospheric Administration scientists pegged the number of North Atlantic right whales alive in 2016 in the low 440s. Scientists now say it’s likely that there are not more than 411 left.

The calculation is based on a trove of statistical data, observations of individual animals and a wave of observed mortalities, with no newborn whales observed in the most recent calving season.

“It continues to be what I call grim,” says Charles “Stormy” Mayo, a whale specialist at the Provincetown Center for Coastal Studies.

Mayo is one of many observers who say without new action, the trend line for the whales will lead to extinction within a few decades.

He adds, however, that while there were no newborn whales observed last calving season, there is hope that some 100 fertile females who’ve had an extra year to rest and feed will be more productive this winter.

“And they haven’t been doing anything with regard to pregnancy for the past couple of years," Mayo says. "So I anticipate that we’re going to see a real substantial burst. It’s going to need it to make up for the hollow that we’re in."

Depending on what action federal regulators decide is warranted, Maine’s lobstermen may have to contend with costly new gear changes that aim to reduce the risk of whales becoming entangled in trap rope. Action on the issue is expected early next year.
