A federal fishery agency reported this week that 10 killer whales were caught in the gear of trawl net vessels fishing this year in the Bering Sea and North Pacific waters off the Aleutian Islands.
Only one was released alive, according to a brief Alaska NOAA Fisheries statement posted online. A team is analyzing data collected about the other nine whales to determine the cause of injury or death, and also to determine which stocks these whales belonged to through reviewing genetic information.
Killer whales, also known as orcas, have been entangled in trawl gear off Alaska in years past, but the numbers reported in 2023 are higher. .
“The agency is working quickly to evaluate these incidents and will share findings as soon as possible, after all required analyses are completed,” the statement said.
The agency reported that another killer whale was entangled with longline gear set out by a vessel that a private vessel contracted to conduct a federal fishery survey in the Central Bering Sea. On June 7, a dead whale was observed caught up in gear, the statement said. NOAA Fisheries scientists were on board the survey vessel, which was designed to provide an assessment of black cod — also known as sablefish — populations, and that incident is also under review.
Bering Sea killer whales fall under the Marine Mammal Protection Act, which includes requirements for vessel owners or operators to report injuries or deaths.
All of the trawl vessels involved in the whale deaths this year were required to carry two federally contracted observers that collect information about the catch. Their observations about the killer whale have been submitted to the NOAA Fisheries team reviewing the incidents.
