Description

Abstract: Rockfish have a gas-filled organ, called a swim bladder, that allows fish to control its buoyancy. When rockfish are brought to the surface quickly, the swim bladder can overexpand and bust. The expanding gas from the swim bladder can push the stomach out of the mouth and the instestine out the anus. These symptoms may get worse with time at the surface. The fish my also float on the surface, unable to dive back to the bottom. Recrpressing or venting the fish may increase the fish's chance of survival.
