Decide before the fish reaches the railHandling & release
California prohibits take of Giant Sea Bass. Plan for immediate release before fishing habitat where an incidental hookup is possible.
Do not gaff or lift the fish for a photograph. Use heavy enough tackle to shorten the fight, dehook in the water when possible, or cut the leader close to the hook when that is safest.
Minimize handling and air exposure, support the fish in the water, and allow it to swim away under its own power.
