Total length of the specimens (male and female combined) varied from 4 to 25 cm with dominant individuals ranged between 12 and 15 cm whereas the body weight varied between 3 and 155 g. The length frequency data were analysed for the estimation of population dynamics and the power coefficient <em>b</em> of length weight relationship was estimated as 2.83. Other measurements were as follows: asymptotic length, <em>L<sub>∞ </sub></em>= 26.25 cm; growth coefficient, <em>K</em> = 1.00 year<sup>–1</sup>; total mortality, <em>Z</em> = 2.43 year<sup>–1</sup>; and natural mortality, <em>M</em> = 1.82 year<sup>–1</sup>. The fishing mortality (<em>F</em>) and exploitation ratio (<em>E</em>) were 0.61 year<sup>–1</sup> and 0.251 respectively. The Biological Reference Points (BRPs) with Gulland method for this fishery (<em>F</em><sub>opt</sub>) was estimated 1.82 year<sup>–1</sup> which is higher than current fish mortality. Therefore the present study shows that the <em>J. dussumieri</em> fishery is safe in Pakistan.</p>}, number={2}, journal={Journal of Fisheries}, author={Baset, Abdul and Liu, Qun and Liao, Baochao and Waris, Abdul and Yanan, Han and Qingqing, Zhang and Ahmad, Imtiaz}, year={2020}, month={Jun.}, pages={777-783} }
