Abstract

The effects of fishing mortality on the spawning potential of a stock. In presentresearch, spawning stock biomass of Otolithes ruber was carried out using Virtual Population Analysis (VPA) data (based on previous study) in the coastal waters of North-West PERSIAN GULF. Spawning stock biomass ranged from 4110 to 11756 tonnes, and fishing mortality ranged from 0.28 to 0.96 per year. Spawning stock biomass per recruit ranged from 22.8 to 44.7%, and avererage spawning potential ratio estimated between 26 to 31%. Fisheries mortality showed a strong and negative correlation with spawning stock biomass per recruit. Percentage spawning potential and SSB/R showed that they are lower in the some years in the range of biological REFERENCE POINTs. However, this assessment finds that the stock is near full exploited. But according to REFERENCE POINT’s results, sustainable stocks need actual planning by fishery managers.
