I'm curious what methods APHQ members use for controlling their fish population.
Here in Florida -- as far as I've been able to determine -- it seems that I'm limited to Blue Tilapia. Hybrids and other variants are prohibited. That seems to rule out breeding hybrids to favor primarily-male fingerlings.
I've read about treating with hormones and whatnot, but I'm curious what other methods are out there and what results others have had with them.
One technique I read about involved using netting of some sort about an inch from the bottom of the tank, which was supposed to keep the females from being able to get to the eggs once they are released. Since it was listed on the page of someone trying to sell fingerlings, though, I was a bit skeptical. Does such a method actually work or would I be better off searching for some fish-sized condoms and forcing the juvenile fish to watch re-runs of MTV's "Teen Mom"?
Would keeping some predatory fish stocked in the tank be more hassle than they are worth?
Just evaluating my options... I don't currently have a system set up yet, but overpopulation is one concern that I wanted to work out the logistics of ahead of time.
Thanks.
