Because of the demand for multiple uses of public waters, it is important to know what impact heated water will have on the receiving water body. (Ketchum 1972). This study examines the effects of heated effluents on the growth and survival of brown shrimp, Penaeus aztecus, and white shrimp, P. setiferus. These shrimp were cultured in ponds near upper Galveston Bay, Texas, which received a constant flow of cooling water from a power plant. The use of shrimp as in situ indicators of water quality and the benefits of using thermally enriched water for shrimp culture are examined. The specific objectives of this study were: to determine the effects of discharge water on growth and survival, to evaluate the possible benefits of thermal effluents for culturing, to relate water temperature, conductivity, and dissolved oxygen to growth and survival, and to investigate the effects of supplemental feeding and stocking rates on growth and survival of shrimp.
