Yes, they will control the FA. A few pointers:

Stock enough to control the FA. I've had poor results at 17#/acre and less, great results at 40#/acre.

Make sure the stocked fish are large enough to avoid predation by any other fish in the pond.

If stocking Blue Tilapia, remember that they do best in water temps above 60°F. They get sluggish below that, although they can survive in waters that dip below 50°F. They all die in waters below 45°F.

Other species of Tilapia need warmer water than that, IIRC 65°F and greater.

Where are you at in Indiana?
