I'm not familiar with that fish but a quick google said they can live between 30 meters and deeper. Some fish don't do well pulling them up from the deep water, the swim bladder swells up and they can't go back down. Haddock can't go back, Pollack can. Just a thought.
Deep water release devices are available for those fish that have swim bladders.
