Fish and fisheries of Virla Reservoir of West Nimar, District M.P., India

Abstract

During course of study on virla reservoir West Nimar (Kargone) M.P., India, total 29 species of fish biodiversity were recorded these belong 6 orders, IO families and 16 genera were observed. On the basis of economic importance fishes weredivided into three major groups viz. catfish (Mystus seenghala, Mystus tengara, Wallago attu and Ompok bimaculattus), major carp (Cat/a cat/a, Labeo rohita and Cirrhinus mrigala) and miscellaneous (Channa sps., Mastacembelus sps. and Notopterus notoptereus). The water body was divided into three zones viz. upstream zone, reservoir zone and downstream zone for fish catch. Tha total annual fish catch computed in this water body was 2465.40 kg. and 2576.40 kg. during the 2001-02 and 2002-03 respectively. The minimum catch were observed in August while maximum in May. The percentage composition of major carp shows decline trend and catfishes shows increasing trend during two years study time. Catch per unit effort (CPUE) ranged between 0.015 to 0.191 kg/ hrs. The water level fluctuations and fish production show inverse relationship.
