Abstract EN
The growth parameters, mortality coefficients and exploitation rate of Penaeus semisulcatus in Jizan fisheries were determined during the fishing season 2015 / 2016.
The growth curves and parameters were estimated using length-frequency data for combined sexes (pooled data).
The S S growth parameters (L∞, K & to) for the sexes combined are estimated as L∞ = 94.40 mm, K = 0.81year-1 , tRoR = -0.20 year, M = 1.634 yearP-1 P, Z = 3.124 yearP-1 P , and F = 1.961 yearP -1 P.The results indicated that, the current exploitation rate 'Ecur = 0.628' was higher than that required to get the maximum sustainable yield per recruit 'ERmaxR=0.581 .In the present study B/R was found 5.98 gm.
The current biomass per recruit ratio indicates that the current exploitation rate is not suitable for maintaining a sufficient spawning stock biomass of P.
semisulcatus in Jizan area which indicates that the stock status of fisheries is currently overexploited.
