Bill - In addition to the 30' jetty, the pond initially had a lot of curly leaf pondweed that probably provided cover. The pondweed is almost gone, but I have not tried to catch any crayfish to know how they are doing. The SMB seem to have grown at an amazing speed based on one I caught 2 years ago when I last fished the pond, and the ones my neighbor caught last fall, but I have GSH, YP, and LCS in the pond which may be the main forage for the SMB. I also have a significant amount of marginal plants and water lilies which may provide cover for the crayfish. I only added 100 so if they removed almost all the pondweed, they must have initially thrived. I know there is a lot of speculation here, so without more investigation of my pond on my part, that is all it is. For me it is just a fun hobby. Also have RES in pond.
