Well, if you insist on being obstreperous, WHAT PART OF SPLAKE DON'T YOU UNDERSTAND? Maybe if you can't tell a splake from a walleye, even with an identification of the fish in question, your not having "seen a distressed fish" tells you that you need to have your eyes checked. And for your further edification, the bait was not petrified.
We also caught lake trout in Loughborough Lake with big heads and skinny bodies back ten or twelve years ago when the smelt population crashed, that had undigested bits of plastic baits in their stomachs and intestines, and APPARENTLY blocking their digestive tracts. I am not a fisheries biologist, I am an angler that takes note of unusual things when I catch and/or clean fish.
BTW please note that I EAT fish, quite a bit in fact, and resent your inference that I or the other folks posting on here, are members of the extremist animal rights organization you name.
