For us it is very important that we conserve our fishery in order for it to be sustainable as well as try to ensure maximum survival of the fish we release.
The correct venting procedure has been reproduced below from the NOAA website Sea Grant Florida and the link to their page is below:
It is best to vent the fish as quickly as possible with a minimum of handling. If the fish’s stomach is everted out of the fish’s mouth, do not attempt to push it back into the fish’s body. Expelling the swimbladder gases will allow the stomach to return to its normal position within a few hours. Hold the fish gently but firmly on its side and insert the venting tool at a 45-degree angle approximately one to two inches back from the base of the pectoral fin. Only insert the tool deep enough to release the gases - do not skewer the fish. The sound of the escaping gas is audible and deflation is noticeable. If a fish is extremely bloated, use the hand holding the fish to exert gentle pressure on the fish’s abdomen to aid deflation.
Keep a good grip on the venting tool during the entire process, so that an unexpected jerk from the fish does not dislodge the tool and cause injury to others.The fish’s everted stomach should not be punctured. This practice is not as efficient in releasing gas from the body cavity and results in additional injury.
Return the fish to the water as soon as possible. If necessary, revive it by holding the fish with the head pointed downward and moving the fish back and forth to pass water over the gills until the fish is able to swim unassisted.
