Ive heard of the keeping them in a tank for awhile. I have never done it so cant tell you if it works or not.
We would shoot the big snappers in the head and emediatly cut it off and hang it from the tail and let it bleed out. then cut aroud the shell on the bottom and skin and remove the legs. Ive never tried snapper tail but im sure it would be fine. The back strap on those things are hard to get to but its the best meat.
You will be amazed how long after the kill they are still moving around. I had one snapper heart beating for at least 3 hours after the kill and it kept beating, we had to go to work so we had to toss the beating heart back into the lake so who knows how long it went for.
