oops, now it was assumed I was advocating to do something illegal. Certainly am not. I was only sharing observation that rusties are everywhere already (I hope they moved from bow to bow legally somehow). While I see why efforts to slow spread may still be important, it seems the foodchain has adapted well (or even appreciated their presence in some case) and it might be time to shift prevention strategies back towards other invasives where the efforts might pay off.
Kind of like the marijuana habit. Once everyone was doing it everywhere, they made it legal (at least in MI) and directed efforts at other problems. Probably still not wise on many fronts to encourage widespread marijuana use, and I'm certain it is altering our young people's (changing the forage fish ecosystem) minds, but... Sorry, this is probably a bad analogy..
The original question was about muddy water and phosphorous. Yep, too many crayfish will muddy your water...
