Grass carp are illegal in MI, but I also have no vegetation, I rarely see or trap crayfish but I'm pretty sure my crayfish are keeping the veggies counts to zero. It is a bummer for trying to create habitat for shrimp, FHM, etc. Consider crayfish trapping?
If I do have a reproducing population of crayfish, my future SMB will have full tummies.
IT is funny that if I put a bluegill carcass in a crayfish trap in the local lakes that have crayfish and leave it overnight there are dozens of crayfish in the trap later. But when my boy has been practicing with his new air driven pellet gun and is taking out my goldfish, they just float for days. It seems turtles and crayfish like the taste of bluegill better than goldfish
