>>552710>>for bigger fish, just slam a brick against it's head. that shit is retarded. when you fillet the fish the blood gets all over the meat, and you look like a doofus smashing away at the fishes head. not to mention it makes rigamortis set on much quicker. The fish may be concussed, however it's brain will still be sending sporadic nerve signals.
It's best to practice ikejime, and then cut the area below the gils like picture shown, bleed the fish out into a bucket or the body of water [salt water being best]
