A total of 591 individuals were collected monthly by experimental beach seine. The monthly length-frequency data (total length in cm) were obtained and analysed using the FiSAT II software and its sub-program ELEFAN for the evaluation of population parameters. Asymptotic length (L?) and growth coefficient (K) were estimated at 22.1 cm and 1.5 yr<sup>-1</sup>, respectively. The growth performance index (?’), longevity (t<sub>max</sub>), and the theoretical age at birth (t<sub>0</sub>) were calculated as 2.86; 2.827 yr, and -0.11 yr<sup>-1</sup>, respectively. Total mortality (Z), natural mortality (M), and fishing mortality (F) were calculated at 3.57 yr<sup>-1</sup>, 2.48 yr<sup>-1,</sup> and 1.09 yr<sup>-1</sup>, respectively. The probability of capture was calculated as L<sub>25 </sub>= 13.45, Lc = 14.34 and L<sub>75 </sub>= 15.08 cm. The recruitment pattern is a continuous two-peak model, with the minor peak occurring in May and the major peak occurring in August. The current exploitation rate (E<sub>current</sub>) and maximum exploitation rate (E<sub>max</sub>) were calculated as 0.31 and 0.421, respectively. Further, the current rate of exploitation of <em>G. nigri </em>was slightly lower than the maximum exploitation rate. The results showed that the <em>G. nigri</em> stock was not overexploited.</p>}, number={4}, journal={International Journal of Aquatic Biology}, author={Faye, Alioune and Sarr, Alassane and Diouf, Malick and Ndiaye, Waly and Fall, Jean and Diankha, Ousmane}, year={2023}, month={Aug.}, pages={279–287} }
