The stock status of 21 commercially important marine species in the Persian Gulf and the Gulf of Oman that was assessed through Stock Reduction Analysis. Species were selected based on availability of population dynamics data from scientific sources, and also the availability of single-species annual catch statistics. The exploitation rate was estimated for the following species: Lutjanus malabaricus (0.44), Saurida tumbil (0.68), Pampus argenteus (0.64), Parastromateus niger (0.48), Portunus segnis (0.66), Platycephalus indicus (0.48), Sardinella sindensis (1.0), Lutjanus johnii (0.47), Rachycentron canadum (0.20), Nemipterus japonicus (0.46), Pomadasys kaakan (0.40), Otolithes ruber (0.60), Scomberomorus commerson (0.38), Rastrelliger kanagurta (0.80), Scomberomorus guttatus (0.62), Acanthosepion pharaonis (0.76), Encrasicholina punctifer (1.0), Protonibea diacanthus (0.14), Metapenaeus affinis (1.0), Penaeus merguiensis (1.0), Trichiurus lepturus (1.0). Short-lived species, such as Banana Shrimp, White-headed Shrimp, Anchovy and Sardine, showed strong stock recovery due to significantly reduced fishing effort after the catch season. Similarly, Horse Mackerel stocks remained healthy to be exposed to the absence of industrial fishing in recent years. However, most species are affected by fishing pressure. To promote stock recovery, it is recommended to reduce fishing effort, increase the selectivity of catches by regulating the mesh size of gillnets and traps, and protect spawning populations by restricting fishing in spawning grounds and during spawning seasons. These measures are essential for ensuring the long-term sustainability of these aquatic resources.
