Six experimental brackish water ponds, three of which received secondary treated sewage waste and three as controls, were seeded with larval and postlarval species to study productivity, nutrient cycling and development of communities. A number of faculty and students from the University of North Carolina studied various phases, productivity, carbon metabolism, phosphorus budget, nitrogen, bacterial heterotrophy; standing crops of phytoplankton, decapod crustaceans, fishes, mollusks, algae, etc. Ponds receiving treated waste had high productivity, wide fluctuations in oxygen and pH, and dense algal blooms. Some functions of tertiary treatment and promise for production of selected marketable species are indicated.
