Abstract

Chemical and biochemical oxygen demands were measured in the feeds used and in the inlet-outlet water at some freshwater trout farms. The oxygen consuming potential of 1 kg feed corresponded to 5–10 population equivalents. The biochemical oxidation rate during 10 days of the “net loading” (BOD outlet-BOD inlet) was equal to that of sewage. Characterizing the organic loadings from fish farms in terms of population equivalants therefore seems proper. The regression of COD on BOD 7 was also calculated.
