I agree with Don's observations. My experience is that BG benefit from the presence of Tilapia not suffer. Studies of lakes in Mexico where Tilapia survive year around have pointed to the possibility that older Tilapia may consume eggs and fry. In lakes with heavy commercial netting in Mexico, there is no evidence of Tilapia feeding on eggs, but where there is no netting (of the older fish), there is some evidence of reduced LMB recruitment.
Ryan,
Do you happen to have a reference for that paper? It certainly does not agree with actual observations every summer in my ponds, i.e LMB preferring BG over Tilapia.
