Earthen Ponds – giant grouper
Ponds are commonly used in many aquaculture operations across the world because they can be low-cost and easy to construct. Ponds for giant grouper culture are prepared and fertilized, then may receive adult tilapia to feed on the naturally occurring algae and to serve as live prey. The giant grouper fingerlings are added a month after the tilapia, and additional feeding commonly occur. Grading takes place periodically to reduce cannibalism, and the pond’s water quality is typically tested daily, with aerators used as needed.
