FISH DIVERSITY AND HABITAT RELATIONSHIP OF SELUM NULLAH AND AIK NULLAH WITH REFERENCE TO PHYSICO CHEMICAL PARAMETERS AT BARI BRAHMANA, JAMMU DISTRICT, J8K

Abstract

The present study was conducted to access population structure of Selum nullah and Aik nullah, the diversity rich perennial tributaries of river Tawi. Present study depicts the presence of total 14 species belonging to 10 genera and 4 families in Selum nullah and 20 species belonging to 15 genera and 8 families in Aik nullah including 13 species in common. Both the study stations are dominated by order Cypriniformes including family Cyprinidae. To draw a better and authenticated picture of the data recorded, a measure of species richness and evenness of their distribution were also under taken. The total number of species recorded in both the study areas show good indication of species rich diversity though the water bodies are moderately polluted but all the variables of water bodies are within permissible limits. Though this study is first of its kind with no previous data record on abundance but, this study will provide base line data for conservation strategies in future.
