I've had thoughts along a similar line. I don't know the first thing about Tilapia, other than I don't want them competing with my BG, but if they reproduce like gangbusters and eat FA....isn't the FA introducing or elevating the DO content to some degree?
It almost sounds like adding the initial brooders (the same as adding any other fish) will impact the biomass of the BOW immediately, then as reproduction takes hold and their numbers increase, AND they aggressively target the oxygen producing FA, the carrying capacity of the pond will be reduced?
What am I missing? Is it a case of having the Tilapia die out over winter and hoping that they don't contribute to eating themselves out of DO before they expire?
If stocked together with GC in an unaerated smaller BOW, is there cause for concern regarding too drastic reduction of aquatic growth, resulting in reduced DO available for the other fish species present?
