ABSTRACT Properly constructed sewage lagoons offer an inexpensive alternative to activated sludge and trickling filter treatment. Lagoons are more efficient, and convert sewage nutrients to plants and invertebrates. Dietary salt and water softeners produce mixomesohaline conditions in lagoon mariculture. Laboratory evaluation of lagoon biomass has shown a potential for animal food. We have determined the amino acid, lipid, carbohydrate and ash content in the product. In addition, the levels of vitamins (biotin, cobalamin, naicin, pantothenic acid, total B 6 , riboflavin and thiamine) have been found in the biomass. Our evidence on the fate of enteric pathogens compliments well‐documented studies at other laboratories which indicate that the material is safe for consumption. Integration of sewage lagoons, with other types of sewage treatment is possible in order to provide the lowest cost of sewage treatment, with the potential for production of a nutritionally valuable food supplement.
