I guess if your goal is to grow trophy LMB, then Blues might compete with them for forage ...
There's the rub. There's a few of us who see LMB as a tool towards other purposes, but I think "Trophy LMB" is still a primary goal for most pond owners (who have a goal).
True, I agree with that. On the stipulation that you don't care about producing trophy LMB, are there any downsides to BC?
I have a 2 ac pond. How many pounds of predator can I support? One uncatchable, dog-eating, fifty pound blue cat and nothing else? No thanks!
Understandable. I guess you would somehow need a reliable way to harvest fish that are "too big" for your liking.
