    Author(s): Elsayed Farrag*, Ibrahim Al-Jamali, Carter Subbaih and Mustafa Al-Shaer

    The growth, mortality and yield per recruit of the blue swimming crab Portunus pelagicus were examined from southern Arabian Gulf off the United Arab Emirates between January and December 2021. The FiSAT II software was used to perform the estimate of growth, mortality and exploitation rate. In the present study, asymptotic carapace width CW∞ and growth coefficient K for males were estimated at 17.01 cm, 0.31y-1 and for females were 18.27 cm and 0.52y-1. The growth performance index was calculated at 1.95 and 2.24 for males and females. The overall ratio of males to females was obtained at 1.0: 0.91. Annual instantaneous total mortality (Z) by length converted catch curve was estimated at 0.76, 1.51 and 1.53y-1 for males, females and combined sexes respectively. The mean rate of natural mortality (M) was evaluated at 0.54 y-1.. View More»
