Study on Fish Diversity Indices in Bhima River from Gursale Village, Dist. Solapur (India) A. N. Dede Department of Zoology Karmaveer Bhaurao Patil Mahavidyalaya, Pandharpur 413304, District Solapur (MS) India Abstract— The present study investigates fish diversity indices in Bhima River from Gursale village, Dist. Solapur. The present study was observed 25 species of fish belonging to 18 genera and 13 families during Jan 2014 to Dec 2014. The fish was high number in winter season and low in monsoon season. The diversity indices of fish indicate status of water quality. The diversity indices are fluctuation all months. The cyprinidae species are dominated in study area. The Shannon diversity indices were indicates pollution status of water. Key words: BhimaRiver, Diversity Indices, Fish, Solapur
are not study in Bhima River. Thus there is an insistent need for proper investigation and documentation of the fish diversity indices and seasonal variation. II. MATERIAL AND METHODS A. Description Site Gursale village is situated in the Solapur district of State Maharashtra. Bhima River is runs near Gursale village. It is situated in latitudes 170 43’ 50.2’’ N and longitudes 750 18’ 36.4’’ E (Fig. no.1).
I. INTRODUCTION The diversity of species or groups of organisms is much partial by the functional correlation between trophic levels (15). The distribution and composition of the fish species in each habitat were closely related with various factors such as the availability of food, breeding sites water current depth and physicochemical parameter of water bodies (7). Pisces are diverse class at taxonomic level and have maximum species which is equal to other to entire vertebrate combine together. In all types of water fish population appears to fluctuate in abundance and in species composition from year to year (3). Fish assemblages of fresh water habitats in general and that of river in particular show great variation. Several reasons can be attributed to these variations.The fish plays are important role in the development of a nation. Besides being a cheap source of highly nutritive protein, it also contain essential required by human body, (22)The significant of monitoring fish assemblage is primarily to comprehend the characteristics of fish fauna understand of which is necessary for successful conservation and management of fisheries resource (6). The dynamic feature of the river ecosystems are the result of change in rainfall in nesting and growth area (24). Fish assemblages of fresh water habitats in general and that of riverin particular showgreat variation. Several reasons can be attributed to these variations. In aquatic ecology these variations in thestructure of fish assemblages are highly important andhence measurement of these variations in their diversity is an important assignment of ecologists. Geological relations with other water bodies affect the species diversity (4). The freshwater fish fauna is highly threatened due to the presence of dams and water diversions, resulting fragmentation of habitat (14). Maharashtra is one of the most important in freshwater fish diversity therefore it is one of the important state in fish production and natural water resource and there is great scope of developing fisheries in this state. Fish diversity is decline rapidly each day due to interminable anthropogenic stress. This diversity is not only the riches of our world but it also has some serious suggestion on fishery. However, no detailed fish diversity has been available on Solapur district. The Study of fish diversity indices and seasonal variations

Collection of Sample Water sample were collected from Bhima River near Gursale village every month during Jan 2014 to Dec 2014 in the morning between 8 to 11 am. The fish was monthly collected in selected Station by different types of net size i.e. Gill nets, cast nets, trap nets, long line and hooks. C. Biological Analysis The fish was collected by different types of nets and photography was taken immediately with the help of digital camera. The total number of fish species was counted immediately for captured by different types of nets and recorded immediately. Fishes were brought to laboratory and preserved in 10% formalin solution in Separate specimen jar according to size of fish. (10) Identification of fish was done up to species level and also nature of colour, scale, fin, food and also with the help of standard key, (5, 11,). Fish was also identified and confirmed in ZSI Pune. D. Statistical analysis of Diversity Indices The Fish was subjected to the analysis of diversity using different Diversity indices. Species diversity index was calculated using the Shannon-Wiener function (21). Species richness was calculated by (12, 27,).Index of Dominance by (23) and Evenness was calculated by using the Formula of (16).The Statistical analysis was also used as PASST Software.
