Killer whales have been entangled in trawl gear off Alaska in years past, but the numbers reported in 2023 are much 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 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.
In a written statement, the Groundfish Forum, a Seattle-based trawl fishery group, confirmed that member vessels were involved in at least some of the whale deaths as well as the one released alive. For decades, killer whales have been drawn to fishing boats off Alaska. Longliners, which drop lines of baited hooks, have generated many of these encounter reports. The whales eat black cod, stripping them off of hooks, as they’re brought to the surface.
“In 2023, our captains have reported an increase in the number of killer whales present near our vessels, where they appear to be feeding in front of the nets while fishing,” said thefrom the Groundfish Forum, which called this “new behavior” that hadn’t been previously documented. In the North Pacific, adult killer whales are long-lived and reproduce slowly. The males can reach an age of at least 50 years and the females as old as 80, according to an Alaska Department of Fish and GameThe fish-eaters feed on a wide variety of species, and large groups are often involved in hunting their prey. Typical dives last three to five minutes, but a lot is unknown about their diving behavior, according to the Department of Fish and Game document.
