Crappiemagnate is correct, I believe. I learned this decades ago. Screwed up some really good eating by cooking them too soon after cleaning live fish--thought I was really doing a great thing. I think the deal is that "rigormortis" needs to set in for a while. We used to put fish we caught into an ice chest in the boat, and would actually cook them on a Coleman stove while we were fishing, but they were D-E-A-D and COLD. Doesn't seem to matter much if they warm up to room temperature while you're frying the fish.
