Was there anything that I said to make you think I was going off thread or what you posted? Remember the old saying crap flows downhill? This is going to prove crap does and will flow uphill in the form of the top of the food chain. Carp are bottom feeders, yes the occasional one may take a minnow bait or fly or crawfish but in any waterway where there is silt you have carp sucking up mud looking for something to eat. Heavy metal and other pollution is in that mud and silt. So the carp carry this crap, the bass eat the carp and carry the crap. Next stage is something like the otter, eagle, bear in their respective area, the alligator in his area on and on all these animals carry the crap consumed by the lowly carp. The more these top species eat the carp the more crap it has in it's system. The older the fish the more crap it has. This toxin built up in their respective host cannot be good for them.
I just realized if you are not careful and transpose a couple of letters crap goes to carp and carp goes to crap . Pretty fitting in my above statement don't you think? I need a proofreader to make sure I have my crap and carp in the right context,
