A total of 662 individuals were sampled in the Dhofar region along the southwest coast of Oman in the Arabian Sea from June 2021 to May 2022. The length-weight relationship for combined sexes was W=0.0151 TL^2.7221. The average monthly values of the gonado-somatic index and the percentage of different maturity stages of gonads for males and females indicated that <i>S. jello</i> spawns throughout the year, with spawning peaking from June to August. The length at first maturity was estimated at 71.9 cm TL for males and 74.0 cm TL for females and the age at first maturity was 4.1 and 4.3 years, respectively. The determination of age derived from the sectioned otolith reading revealed that the age of the studied fish varied from one to 24 years with the dominant age of 3 years old. The longevity of <i>S. jello </i>was calculated at 27 years old. The values of growth parameters in von Bertalanffy growth function for combined sexes were estimated as: <i>L&infin;</i>=161.18 cm, <i>K</i>=0.119 уr^-1 and <i>to</i>= -0.88. The present study indicates that <i>S. jello</i> is a long-lived species with slow growth rate, so it is vulnerable to overfishing. Further monitoring studies of <i>S. jello</i> are needed to develop scientifically sound and effective management measures for their fishery.</span></span></span></span> Pickhandle barracuda, Sphyraena jello, Reproduction, Age and growth, Oman, Arabian Sea 151 169 http://jifro.ir/browse.php?a_code=A-10-4930-1&slc_lang=en&sid=1 A.
