According to that chart the Northern Crayfish should be an excellent food source for predator fish, thanks for the info, I do know that several local BOW that I fish in in this area have a lot of crayfish and the predator fish really love them, and for the most part, with a stomach full of digesting crayfish remains, they seem extremely healthy looking and vigorous, I have never weighed and measured any to establish a relative weight percentage, I didn't realize there was such a thing at the time. I am watching that in my new pond, and am for the most part at 100% plus, and I'm thinking they are getting lots of craws. the pond is built in and old sandy creek bed with an even bigger creek going across behind, parallel to the dam.
