The pond is 3 acres in north Florida. I stocked 400 X 3" Tilapia two different years when I should have been removing predator Biomass. I have discovered that at least a half dozen mature 18"males have survived. They must have spawning beds nearby as they arrive very quickly when I hand throw food. No smaller tilapia & no females have ever been seen, just the big bruisers.

What are the chances that I have lurking females somewhere in the pond? Anyone with an opinion or SWAG?

Females are the smaller fish, develop slower, hence more likely to be eaten. I am not optimistic, but they do not associate with the males unless they are ready to mate, then pick up their eggs & leave.

I will continue to throw feed into the early winter & see what happens.
