Would the fastest growing CC be the ones that "win" the spawning rights? If so, then I would be naturally selecting for the CC that would be preferred for the pond's goals.
From what I gather, the larger CC spawn first, as they all don't spawn at the same time. If you created one piece of spawning structure, it could get used by multiple pairs during the same season. Catfish farms that use the pond-spawning method usually have 1 spawning container for every 2-4 breeding pairs. See? All that Youtube research has paid off! Lol...
