Provide precautionary measures for sustainable harvesting of Ribbonfish stocks (Trichiurus leuptrus, Linnaeus, 1758) in the Persian Gulf and Sea of Oman ecosystems.

In the present study, time series data of catches of Ribbonfish (Trichiurus leuptrus), in the Persian Gulf and Oman Sea from 1973 to 2018 were used and the fishing trend and average relative increase rate of catches of this species for this period estimated. Using fishing trend (linear regression equation) and average relative increase rate in catches of Ribbonfish over 21-year period, the amount of harvest for the next 5 years (2019-2023) for the whole Persian Gulf and Sea of Oman and for each province, were predicted. Finally, the harvests of 32000 t, which ensure sustainable exploitation of Ribbonfish and sustainability of jobs created by this fishery in the Persian Gulf and Sea of Oman, proposed and recommended to Iranian fisheries authority for implementation.
