When we were camping one summer, my father was filleting a northern pike. He likes to refridgerate the slabs after he takes them off and takes the skin off so they firm up a bit and it makes it easier to take the bones out. Anyway, five or so hours later, he takes these slabs out when some buddies come over so he can show them how to de-bone a jack fillet. The one fillet started to twitch on the table. You couldn't actually see it move up and down or anything, but if you felt the fillet, you could feel a twitch, and each person that felt it could feel it so it wasn't a pulse from my hand or anything lol. I don't know how that is possible five hours later and not being connected to any nervous system or anything.
Just a few days ago when we were filleting whitefish, one had waterbeetles in its stomach that were still alive and moving around. I wonder how long those things can live inside a stomach for lol. Dad also found a hook inside a northern pike stomach once. I thought it would have got caught up in the mouth or throat before it made it that far.
Anyone else find interesting things or have wierd things happen when filleting a fish?
