A total of 1685 length-frequency data were collected by the midwater trawl method. The average total length was 28.7±5.9cm; ranging from 18.0 to 47.5 cm. The most frequent length class was calculated 24-26cm. The length-weight relationship was found as W= 0.00895L<sup>3.0256</sup>, showing an isometric growth. Growth parameters of L∞ and K were estimated at 50 cm and 0.20 yr<sup>-1</sup>, respectively. Parameters of t<sub>0</sub>, T<sub>max</sub> and Ǿ were calculated -0.70 year, 14 years and 2.69, respectively. This species has two recruitment periods, a major peak occurred at 23.14%. Three cohorts were distinguished annually with a mean length of 24.16, 34.41 and 41.48 cm. Total, natural and fishing mortality rates were calculated 0.54, 0.46 and 0.08 y<sup>-1</sup> respectively. Due to the calculated exploitation rate (0.14) in the period of study, the stock of <em>A. nibe</em> in the Oman Sea was not under the pressure. The probability of capture (L50) was determined 33cm in total length, was less than the reported L<sub>M50 </sub>(35 cm) of <em>A. nibe</em> in the Oman Sea, and it was found that the used gear mesh size was not suitable for <em>A. nibe </em>fishery.</p>}, number={1}, journal={Iranian Journal of Ichthyology}, author={SALARPOURI, Ali and BEHZADI, Siamak and VALINASSAB, Tooraj and KAYMARAM, Farhad and VAHABNEZHAD, Arezu and MOMENI, Mohammad}, year={2022}, month={Nov.}, pages={43–53} }
