What species of craw - yes it matters. Assuming the right type of craw then divide up what you have into the number of rock piles and dump them there.
An upcoming issue of PB mag will have an article on craws and their effect on BG and LMB/SMB spawning.
I've wondered about that. Do crawfish prey on fish eggs/nest? I would assume they do but don't know that for a fact.
