Never club them. Slide the tip of your filet knife right between their eyes. Saves time, effort and holes in the boat.

Taught to cut the gills. Bleeds them out and the flavor is improved.....
Or pour a few shots of rotgut rum over their gills. Gives them a happy goodbye blast and they never move a muscle.
if you take a sip of rum and spit it into their gills, it puts them into a permanent coma, no matter how big the fish.
I like to clean the fish right away and sometimes I put it into a bucket of ocean water w extra salt added to “brine” the fish for a half hour before replacing the salt water w fresh water, then draining b4 cooking-this takes any fishy taste away. Works really well with sharks and rays, when you realize a stingray tastes just like $200 of scallops you start hunting for them.
