Deb :

I am interested in your comment above "...eventually producing a pheromone that stunts all growth." I assume you mean BG (lepomis) growth. I have read that wrt G.shad and crappie they inhibit all growth that way and seen speculation on the effect of BG stunting on the population of BG and the possible causes. One I recall indicated the ability of the female BG to sense crowding and as a result greatly cut back on spawning. I was wondering if you could elaborate on your point above and direct me to any studies or sources as I have wondered about it. I have seen studies that state BG release a chemical warning indicator when predators are near and a test on if they could inhibit LMB reproduction by chemical release which was negative on that point.

Aren't you glad you stayed -- I am ! Please no one think this is a put Deb on the spot question. It is not. I don't know the answer , think it could be true, and would be greatful if anyone has info on the subject.
