Abstract The purpose of this study was to develop a framework for investigating the catch trend. However, it is currently difficult to provide scientific advice for management purposes using only catch data. This article presents a data poor method for stock assessment of Scomberomorus guttatus by collecting catch data in the Persian Gulf & Oman Sea. In this study, CMSY method was used to determine the biological reference points (BRPs) of Indo-Pacific king mackerel in the study area. Catch data was collected from 1997-2022 in the Persian Gulf & Oman Sea. The average catch of the Persian Gulf & Oman Sea was 5750 tons in the studied period. The average (minimum -maximum) of carrying capacity (K), maximum sustainable yield (MSY), the biomass of maximum sustainable yield (Bmsy), current biomass (B) and Fishing mortality of maximum sustainable yield (Fmsy) were obtained by the Catch- maximum sustainable yield (CMSY) method. F/FMSY was estimated 0.69 in the Persian Gulf & Oman Sea. The KOBE plot indicates that based on the CMSY model results, Indo-Pacific king mackerel is currently not overfished (B2022/BMSY=1.35) and is not subject to overfishing (F2022/FMSY = 0.69) in the Iranian southern waters.
