Abstract


Cutlass fishes Trichiurus gangeticus, Gupta, 1966, Eupleurogrammus glossodon, (Bleeker, 1860) Tentoriceps cristatus (Kluzinger, 1884) and Benthodesmus oligoradiatus, Parin and Becker, 1970 were collected from the landing centers, off southwest, south east and northeast coast of India during 2020-2021. The present study estimated the length-weight relationship parameter b with the coefficient of determination r2 scores using ordinary least squares regression method. The b values in the relationship W=aLb varied between 2.6306 to 3.3396 and the r2 value ranged from 0.8 to 0.93. Also determined the condition factor of all the four fishes and it indicates wellbeing ranging from 1.02 to 1.1. Present study provides valuable inputs to the species management and stock assessment.
