Shrimp and fishes native to the Gulf of Mexico were cultured in 0.1 ha brackish water ponds. Each pond received a continual flow of heated effluent from an electric generating station in Baytown, Texas. Brown shrimp, Penaeus aztecus, were cultured with Florida pompano, Trachinotus carolinus; Florida pompano and black drum, Pogonias cromis; black drum alone; and black drum and striped mullet, Mugil cephalus. Shrimp and pompano were stocked in early July and June, respectively, and harvested in late October. Black drum and striped mullet were stocked in early June and July, respectively, and continued until early March. Hydrological parameters were monitored daily for interpretation of growth and survival of culture species. These biological parameters along with food conversion efficiency, production and competition were compared among treatments. Marketability was discussed for shrimp, pompano and black drum.
