This study illustrates the population structure (Length Frequency Distribution, LFD), relationship between length and weight (LWR), relationships between length and length (LLRs), Fulton’s condition factor (<em>K<sub>F</sub></em>) and relative weight (<em>W<sub>R</sub></em>) of <em>P. niger</em> in the Bay of Bengal (BoB). A total of 225 <em>P. niger</em> were collected from the four locations during January to December 2020. LFD analysis indicates three length classes 21-27 cm, 30-32 cm and 35-37 cm, respectively. This species showed isometric growth pattern (b = 2.981) that indicates that the size and weight increases proportionally and the surrounding habitat provides favourable environment for the growth. LWR between TL and BW were highly correlated (r² = 0.951). LLRs also showed significant correlation between TL and SL (r² = 0.845) and TL and FL (r² = 0.861). The mean value of<em> K<sub>F</sub></em> was found as 1.60 which indicates that the BoB provides healthy environment for this species. The mean value of <em>W<sub>R</sub></em> (101.09) indicates that the relationship between prey and predator was in balanced condition. This study suggests optimum catchable length for <em>P. niger</em> at 27 cm. Therefore, these findings could provide important information to design effective conservation and management planning for this species.</p>}, number={1}, journal={Acta Biologica Szegediensis}, author={Husna, Asmaul and Mondol, Md.
