Since you will likely miss this spring egg laying and hatch of crayfish I would if feasible for you, stock around 1000/ac or more. If you can't acquire that many stock what you can get. Higher numbers will provide a strong brood stock for next spring crayfish egg production. Once you add the SMB the crays will be heavily be preyed upon and numbers will diminish. Stocking the higher numbers will also help with filamentous algae control as crayfish will eat the FA and Chara common in new ponds.
