What today’s super-sensitive sonar units have shown me is that fish will defecate while fighting on the line. After releasing these fish, the fish poop ever so slowly sinks to the bottom – a rain of poop, if you will, in the ice hole, for several minutes after the catch, depending on depth. Seemingly, after one or two fish have done this, my hole will stop producing as well as before. The fish are still close by, just not under this hole.
Am I imagining things? Or, does the fish poop that’s now littering the bottom and water column directly under my hole have something to do with a decrease in productivity? I’m definitely starting to wonder. Anyone else notice this phenomenon?
I believe Gord Pyzer had some theories about fish poop which might play into this.
