Abstract
Pollution of the aquatic environment is a serious and growing problem. Increasing number and amount of industrial, agricultural and
commercial chemicals discharged in to the aquatic environment having led to various deleterious effects on the aquatic organisms.
Aquatic organisms, including fish, accumulate pollutants directly from contaminate water and indirectly via the food chain. The study of
histopathological effects of pollutants on the different organs of the fishes is an important basic effort leading to our understanding of true
impact of pollutants on that ecosystem because the fresh water fish show dissimilar pattern of response when exposed to toxicants. In the
present study the histopathological changes are observed in the gill tissue of the fresh water fish Catla catla exposed to 50% and 100%
concentrations of untreated and 100% treated sago effluent. The histology of gill tissue showed various degrees of deterioration when
compared to control. The deterioration was very much reduced in the treated sago effluent when compared to the untreated sago
effluent.
