The anatomy of a fish is evolved for the neutrally buoyant forces of a primarily horizontal existence in water. When the fish is removed from the water, the resulting force on the anatomy of the fish is dramatically higher. "Settling" by hanging the fish has been reported to tear the tissue as a result of the non-typical force. It isn't a crushing issue. Humans die all the time from side impact car accidents in which no visible damage is done, but a non-typical sideways force causes the aorta to tear. The person appears fine and a few minutes later bleeds out and dies. Those types of injuries, along with dislocated jaws are the concern.
