The rusty crayfish also heavily targets any growing aquatic plants. I know of a lake in Wi. that has a virtual army of rusty crayfish that come out at night and the lake has NO weedbeds since a couple of years after the rusty's were found in the lake. At night as far out as you can see, there is literally 1 rusty per sq. ft. in water up to 6' depth (water clarity limiting the count).

Standing on the pier one night, with a 1/2 oz jig head tipped with a chunk of liver, I caught 200 Rusty's in less than 2 hours sight fishing.
