Here's photo when Mr. Vedder brought it to the surface. The holdup shot was taken a few minutes later.

I have a pretty good guess but have written a biologist in Alaska for verification.

It is really difficult to judge by photos on the internet as many of the photos were taken after various fish were taken commercially at deeper depths.

I can definitely rule out Yelloweye, AKA Rasphead, Canary,Boccassio, and Vermillion. But it gets tougher from there.
