what's the most humane way to kill a fish? I usually let fish go but if i catch a really delicous tasting fish like flounder,whiting,english perch or trout i usually keep it and make a nice battered fish or sahimi i don't like to make any animal suffer, i never use live bait, except for worms cause they don't feel pain, i usually bonk the fish on the head with a stick but i don't think that's humane, how do you humanely kill a fish?
