I've wondered the same thing regarding digestion of algae....don't tilapia poop? And it seems there have been a few posts of late regarding the absence of floaters after the water cools. How can one be sure that all those dead tilapia aren't decomposing on the bottom, out of the reach of terrestrial predators, releasing all those consumed nutrients back into the pond?
Are Tilapia a solution that once implemented, need to be continously stocked from that point on, or do they ever get "done??" With the job?
