An Assessment and Management of Green Tiger Shrimp (Penaeus semisulcatus) Fishery in the Jazan Area (Red Sea, Saudi Arabia)

The maximum sustainable yield (MSY) and the corresponding values of fishing effort (number of fishing days) were estimated for the green tiger shrimp, Penaeus semisulcatus fishery in the Jazan area of the Red Sea. The equilibrium as well as the non-equilibrium approach was used to fit the surplus-production model on the statistical data of catch and fishing effort. The study area extends from Lat 17?40’ N southwards to the Yemeni border which supports the activity of more than 90% of the bottom trawlers exploiting the shrimp fishery in the Saudi Red Sea coast . Results from both treatments indicated that the current fishery for the tiger shrimp is under the level of maximum sustainable exploitation. The maximum sustainable yield (MSY) was estimated at 945.3 and 829.8 tonnes by the equilibrium and non-equilibrium model, respectively. The corresponding levels of fishing effort required to generate the maximum sustainable yield (MSY) were estimated by the two models, respectively at 21.620 and 17.370 fishing days per fishing season.
