The pollutants and drastic environmental variation have also adversely effected and changed water qualities i.e. colour, hardness, turbidity , alkalinity, pH. COD, BOD and TDS etc. Aquatic life, thus, also is affected. Changes in morphology of fish likecolour, pigmentation, length, weight mass, structure of scales, finrays etc. may occur. This cannot be ignored that the afore-mention variation may be responsible to develop new varieties or sub species. Unfortunately, negligible work is done in relation to fish fauna of the area in recent-past. Though, appreciable limnological work is done, yet the fish fauna remained unexplored. The fauna study is of tremendous significance in determining population density and calculating sub specific diversity and conservation of ecosystem in Damoh District
