Abstract :

The aim of this study is to report the length-weight relationship parameters (a and b) for some economically important fish species from freshwaters. The length-weight relationships (LWR) are calculated for 15 freshwater fish species collected during January–December 2017 in Haro river. 15 fish species belonging to 5 families Labeo rohita, Puntius ticto, Puntius sarana, Cirrhinus mrigala, Labeo gonius, Puntius sophore, Catla catla, Rasbora daniconius, Danio Devario, Puntius conchonius, Chanda ranga, Chanda nama, Mystus seenghala, Tilapia mossambica, Wallego attu were caught from the Haro River. The LWR with high correlation coefficient (r2) y = -0.020x + 1.782, R² = 0.006 is significant for all the species. The condition factor for the 15 fish species crosswise over both season extended 1.6450 to 2.3521.These parameters are of great importance to evaluate the relative condition of populations, biology, species management and their fisheries and stock assessment. The application of the length-weight relationships presented here should be limited to the observed length ranges. The low condition figure recorded this investigation could be because of effects of sedimentation. This study has contributed to the knowledge of fish populations in this economically important area that could assist fishery management scientists in carrying out future ecological studies in line with the strategies of conservation, restoration and management.
