As your fish is brought to the boat, the angler should stand in the corner of the boat and the mate should lead the fish past the angler while the photographer shoots your pictures. Avoid lifting these large fish out of the water. Their internal organs were not designed for such stress. Do not drag fish up on the gunwales of their boats for pictures. This wipes off the fish's protective slime and scales, making it vulnerable to infection and disease.
Weak fish are vulnerable to sharks also.
After you've taken your pictures, put your engine in gear and slowly drag the fish through the water until it regains its orientation. The longer you battle the fish, the longer this will take. But it's important if the tarpon's to live and share these thrills with another angler. After the fish regains its composure, cut or break your leader as close as possible to the hook. If you are using a treble hook lure, go ahead and attempt to remove it with pliers if you can.
