Pond Boss Forums STOCKING A NEW POND Types of fish to choose RES x BG hybrid feed trainable?

I think you've hit on a key point John when you point out competition as a major factor. I read an article written by Dr. Willis along the same lines but it was BG and PS. He suggested that PS were more effective at controlling snails, and their associated parasites, when placed in competition with those bully BG for other forage. I followed that suggestion and stocked PS and BG together. My pond went from a heavy snail infestation to almost none and my PS are in the 7 to 8 inch size which I believe is above average for PS but I never see the PS at feeding time. The PS found their niche with little competition for the snails they are thriving. I suspect the RES in your RES only pond will grow faster and larger without the BG competition for the pellets.
