ASSESSMENT OF FISH BIODIVERSITY IN MIDDLE STRETCH OF GOMTI RIVER WITH THE RELATION OF WATER QUALITY PARAMETER.

The present work is aimed to assess the water quality parameter of Gomti river and its relation with ichthyofaunal diversity data and it revealed that only 56 fish species identified in middle stretch of Gomti river and representing 20 families with 37 fish genus. Out of the total 56 fish species only 6 species are exotic fish species. The higher relative abundance was found in small size fishes and IUCN status of threaten categories fishes were also assessed to know the conservation status of fishes. Various fish diversity indexes were measured to evaluate the diversity pattern of fishes and their distribution structure as per ecological point of view like Simpson's diversity index, Shannon_H diversity, Piclou's Evenness equitability index and Magalef diversity index.
