This proposed rule is designed to increase the survival of released reef fish, a top priority management issue in the Gulf and South Atlantic. If approved, this rule would also require the use of a descending device or venting tool if releasing a fish that is exhibiting signs of barotrauma prior to release. As reef fish are reeled up from depth, they can suffer pressure-related injuries known as barotrauma. These injuries include the stomach protruding out of the mouth, bulging eyes, bloated belly, distended intestines and inability to swim down independently. If not treated correctly, barotrauma can be lethal to reef fish.
