Impact of the exotic fish, Oreochromis mossambicus, on the indigenous fishery of Powai Lake, Bombay
Fishes impart the most profound influence on the floral-faunistic characteristics of an aquatic ecosystem. Oreochromis mossambicus, an exotic fish accidentally introduced in the Powai lake, India, caused considerable changes in the growth pattern of Indian major carps, ultimately reducing the productive potential of the lake from 33.0 to 11.9 kh/ha. Powai lake is used exclusively for angling for sport. The angling pressure based on the "creel census" from 1955 to 1976 gives a clear picture of the trends in the fishery therein. A considerable decline, ranging from 171 to 400% in the average weight of Indian major carps was recorded.
