BigJoe's tip

Great hammerheads tire fast and die easily after a long fight — use heavy tackle or avoid areas where they hunt tarpon.

Catch and release

Catch and release: wet your hands, keep the fish in the water when you can, and release it quickly. Use circle hooks and a dehooker.

Stay safe & legal

Safety, rules and taking care of the fishery.

Safety warnings

Never pull a shark onto the sand by the tail or bring large sharks aboard. Cut the leader close to the hook if you can't remove it safely.

Regulations

PROHIBITED in Florida state waters: no harvest, and it must stay in the water. Federal rules also restrict retention. A Florida fishing license is required unless you are exempt; Florida rules are set by FWC (myfwc.com). Federal waters fall under NOAA Fisheries. Other states and countries set their own limits — check before you keep fish.

Conservation

Keep only what you'll eat, release the rest quickly, and follow size and bag limits.
