Abstract
The present study examines the population dynamics of the green tiger prawn, Penaeus semisulcatus, in western Arabian Gulf. Monthly length-frequency samples were collected from Dareen port, between May 2013 and April 2014. Maximum carapace lengths recorded were 38 and 36.67 mm for males and females respectively. The growth analysis using von Bertalanffy model showed different growth patterns between males (CL¥= 51.50 mm; k = 1.77 yr-1) and females (CL¥ = 62 mm; k = 1.10 yr-1). Total mortality was also found to differ between the two genders with 4.65 yr-1 for males and 3.37 yr-1 for females. Estimates of natural mortality of males and females were 2.12 yr-1 and 1.47 yr-1 respectively. In all, the results found herein were consistent with the few published studies on the life history of Penaeus semisulcatus in the Arabian Gulf
