Don't know about the details of the situation, but somehow a bunch of tilapia are in Lake Seminole. People bowfish them and apparently they taste like trash.

I don't know all the preferences of Tilapia but I have discovered by chance that they are used to process a lot of waste from other species of fish and animals. Although I have eaten a lot of "free range" chicken and know they will also process waste. I have quit eating tilapia for that reason and the fact so much of our fish and seafood come from places I am not sure about the food handling procedures.

That's one of the reason they are so popular for aquaponics, it makes growing them more efficient. It takes about 1.25lbs of food to grow a pound of fish biomass. It takes like 8-10lbs of food to grow a pound of trout biomass

So they taste like tilapia? those are garbage fish no matter where you get 'em lol.

I think the issue of cooling water for the trout the (potentially?) heating it for the desired plants, only to re-cool, will be so labor and energy-intensive it'd be absurd. You would spend so much just on the electricity i bet.

Its possible to draw trout tolerant water from the ground. My parents well is over 350 ft deep and the water temp straight from the ground is cool. I've never checked it, but I would guess @ 70*. I know geothermal heating systems use wells to heat and cool, so is a geothermal well suitable for trout?
Then would you have to heat the water to make it compatible with aquaponics?

That puts them in the same range as channel catfish, which I had been told were the most efficient turning food into meat. I really like the way they taste.
