Does anyone know where I could target these guys within a decent drive of the DFW area? I've never caught one before but would love to give it a try.
They are a warm water fish and only survive in warm climates.
If you have any power plant lakes in your area good chance there may be some Tilapia there.
Power Plant Lakes,Warm spring fed rivers, and rivers, lakes where they is no very cold winters are good places to find them. We have a lot of Tilapia in the San Antonio area. The Comal River in New Braunfels is loaded with em. So are the Southwest area rivers.
Side Note: You may want to try Decker. That lake is in your area and is a power plant lake.
