I have a 1 1/4 acre pond with areiation and I stocked 75 Tiger bass last summer.(I already had a bunch of coppernose that were spawning the previous year). I stocked 2" bass in the middle of June and 4 months later they were 12" long and weighted 12 oz. I would like to add some crawfish for them this spring but I don't know how many and if I sould just buy the sacks they sell for crawfish boils or not. Any advice?
