The National Marine Fisheries Service has provided more information regarding the two orcas taken as bycatch last year.
The orcas died as a result of the bycatch. Or as NMFS put it: "Unfortunately, this was a marine mammal bycatch mortality incident."
NMFS declined to name the vessel involved, saying that information is confidential. However, the agency would say this much: "The killer whales were incidentally taken in the Bering Sea/Aleutian Islands flatfish trawl fishery."
NMFS provided an observer's photos from the incident. "All identifying information and metadata have been removed or blurred out in these photos in accordance with Magnuson-Stevens Fishery Conservation and Management Act and Marine Mammal Protection Act confidentiality provisions," the agency said.
Readers are advised the images are fairly grisly, and you might find they take a bit of time to download.

What else?
"Observers were able to collect tissue samples from the whales, which have been sent to a lab for genetic analysis and possible identification for stock of origin," NMFS said. "This analysis has not yet been conducted, as regular lab activities have been delayed due to the COVID-19 pandemic."
Bycatch of orcas in Alaska fisheries is not unprecedented. NMFS cited its most recent
technical memo on human-caused mortality and injury of Alaska marine mammals. Search "killer whale" for a number of regrettable orca encounters with fishing vessels and gear — not only trawl but also longline and pot.
