Fish Diversity and Hydrological Parameters of Indrasagar Reservoir (Khandwa District)

Abstract

The state of Madhya Pradesh is the central state of India & one of the important aquatic biodiversity hotspots of the country, having bestowed with a large number of water bodies both lotic and lentic, the state boasts of rich fish biodiversity. The aim of this study is collection and identification of finfish that found in Indira sagar reservoir and the water quality parameter of the reservoir in which the fishes thriving. Total 54 species of 9 order were found in the reservoir in Khandwa district including labeo rohita,Catla catla, Cirrhinus mrigala, Ctenopharyngodon idella Labeo calbasu, Puntius sophore, Pethia ticto,Puntius chola, Cyprinus carpio, Pangasianodon hypophthalmus, Oreochromis mossambicus, Glossogobius giuris, Channa marulius, Channa gachua , Channa striata and Clarias magur etc. The 03 species of transplanted Indian major carps Catla catla, Cirrhinus mrigala and Labeo rohita are dominating the fishermen catches The authors are of firm opinion that the exotic species are posing competition for food and space to the native species.. To certain extend even hybrid of catla and rohu are available in the fish catches The water quality parameters were significantly found suitable for freshwater cultivable species including the temperature, dissolved oxygen, Total hardness , dissolved oxygen and temperature are higher in summer season and lower in winter season. This may be due to higher photosynthetic rate in summer season. Whereas the pH value is higher in winter season and lower in summer season. It indicates reduction in photosynthetic activities in winter which reduces assimilation of carbon dioxide and bicarbonates.
