September 29, 2017 — ANCHORAGE, Alaska — New research aims to find out why highly endangered beluga whales in Alaska’s Cook Inlet have failed to recover despite protective measures.

The National Oceanic and Atmospheric Administration has awarded more than $1.3 million to the state for three years of research involving the white whales.

“While we know what we believe caused the initial decline, we’re not sure what’s causing the population to remain suppressed,” said Mandy Keogh, a wildlife physiologist with the Alaska Department of Fish and Game.

A population of 1,300 belugas dwindled steadily through the 1980s and early ‘90s.

The decline accelerated when Alaska Natives harvested nearly half the remaining 650 whales between 1994 and 1998. Subsistence hunting ended in 1999 but the population remains at only about 340 animals.

Cook Inlet belugas are one of five beluga populations in U.S. waters. Cook Inlet, named for British explorer Capt. James Cook, stretches 180 miles (290 kilometers) from Anchorage to the Gulf of Alaska.
