Replying to your old post because I watched a Biota video recently and it sounds like now when they harvest deep water fish, they use some sort of container that maintains the atmospheric pressure.That too bad. Its a gorgeous trigger that gets its name from the lines and spots decorating its body. What makes it difficult is a mentioned, its a deep water fish, and if not gradually brought to the water surface, will have bladder or other internal issues making it short lived.
