Increased deposition of cadmium in impounded water through atmospheric fallout and runoff water is a growing concern for aquaculture. In India, pisciculture practices are threatened by frequent low to moderate deposition of Cd in ponds. Although several studies have been conducted on Cd toxicity to freshwater organisms, little is known about the interaction of Cd with other chemicals present in the receiving water system. There is evidence that Cd, in the presence of other chemicals, may produce synergistic, additive or antagonistic effect on aquatic organisms. Aquatic ecosystems, heavily enriched by nitrogen and phosphorus, have reduced the stress imposed by Cd. In contrast, chemicals such as KMnO{sub 4} and CoCl{sub 2} used in aquaculture increase Cd toxicity to fish and plankton. Poultry litter is frequently used in pisciculture ponds to enrich nutrients. However, interaction of poultry litter with Cd is not known. 17 refs., 1 fig., 4 tabs.
