Abstract

Some biological aspects of Channa striatus viz., length-weight relationship, fecundity and condition factor were observed in the laboratory. Sample of 20 individuals of Channa striatus was collected randomly from local market in the Khulna city. The regression equation was found in case of total length and body weight, W = -416.46 + 23.19T (r2=0.896). The arithmetic regression equation of the relationship between the standard length and weight was, W = -382.05 + 26.0371 S (r2=0.908). The regression equation of the relationship between the total length and fecundity was, F = -16046 + 959.671 T (r2=0.859), standard length and fecundity was estimated as F = -14424 + 1070.25 S (r2=0.865) and body weight and fecundity as F = 3965.43 + 32.9612 W (r2=0.764). Among the different linear relationships, total length and body weight relationship was the strongest. Relationship between condition factor and fecundity was the weakest. The fecundity of the species was ranged from 4939 to 22723 and the mean fecundity of the 20 fishes was 14836.050 ± 4019.9612. Maximum fecundity was found in the fish having total length of 38 cm, body weight 475 g and minimum fecundity was found in the fish having total length of 26 cm, body weight 190 g. Condition factor of Channa striatus was found to vary from 0.68167 to 1.35073 with a standard deviation of 0.1748 and the mean value was 0.979 ± 0.1748.
