TGW1, I agree with what was said about the HBCP being a competitor, but ONLY the F1 stocked. Almost all offspring will become snacks, but there may be a low number recruited. Rainbow trout in winter with Tilapia in the warmer months is proving to be an awesome combo in creating double digit bass, fast.
I think you could stock 300 HBCP without adversely affecting your CBLMB growth.
I have a question re Tilapia. Are they really much of a forage fish for bass?
I get where they eat unwanted vegetation and generally don't compete with LMB for forage. And maybe LMB will eat some smaller tilapia from time to time, and even some larger ones when temps cool. But is it really true that tilapia, where fairly common, constitute a major part of a LMB diet throughout the summer?
