Length-Weight Relationship and Condition Factor of Ompok bimaculatus from the Commercial Fish Market of Krishnagar, Nadia, West Bengal, India Amid Monsoon

Abstract

The length-weight interrelation and the condition factor of Ompok bimaculatus collected during monsoon period from Krishnagar, Nadia, West Bengal of India was investigated. Linear regression was significant (p < 0.05) with R2 values 0.73. The intercept (a) of LWR was 0.0002, while the slope (b) was 4.14. The exponent ‘b’ value was significantly higher than 3 (b > 3). Values of condition factor (k) varied between 0.41 to 0.88. High proportion of energy exertion for gonad and unpredictable feeding during spawning season may be culpable for these retarded values of condition factor in Ompok bimaculatus. Further, high value of body relative weight condition (Wr) like 109.471 demonstrated that fish caught from balanced aquatic environment hold satisfactory amount of prey for their good growth.
