Ya, I'm sure there's some good intent of not introducing species in some lakes, ie, pike into a lake of bass and walleye(Mountain Lake) Doug knows what I mean. Or inadvertently dumping gobies or smelt into another non infested body of water. I know for a fact, somebody unaware of the consequences threw some minnows in the local Rod & Gun pond (Catawampus), 2 years later the annual kids trout derby was pretty dismal. One of the guys pulled a 12lb pike out of the pond. I don't have a problem using mashed up dead minnows, unlikely that would do any harm. At the campground we used to dump the salmon and laker guts in the lake and watch crayfish clean that up. One of the outfitters up north bagged all the walleye guts and had an old freezer out back of the cleaning hut and would take them to the dump every week. Oh well.
