Can anyone offer some advice in regards to a type of small fast reproducing fish that could be used in ponds as a food source for larger fish.

Tilapia spawn like mad and the offspring are an excellent feed source for predator fish.

Yes, and Tilapia convert microscopic algae

that already is in the water

to bite size meals for the big fish.

I have a pond with millions of tiny tilapia in it,

with catfish that steadily feed on them,

a great combination,

because they recover lost nutrients back into the food chain.

Should they escape to maturity, it's only a good thing

They breed throughout the year, slowing down if the winter water is too cool

Most Tilapia fingerlings are sold as Male only,

so to get things started you need to find females as well.

A hatchery only needs to not apply the sex shifting hormone to the hatchlings.

The black Tilapia Pla Nin are more vigorous than the orange Tab Tim.

That is the perfect answer thanks so much

If you want good quality tilapia fry that are not sex reversed I suggest you google nam sai farms and contact Warren
