Abstract:   (1905 Views)
Population dynamics and fishery status of Trichiurus lepturus were estimated by landings data on the northern waters of the sea of Oman (Sistan and Baluchestan Province, Iran). A total of more than 3000 fish samples were weighted and measured during one-year study period (October 2016 to September 2017), the growth indices were obtained as follow: L∞=176 cm, K=0.5 (yr -1), to=-0.2 year, M=0.67(yr -1), F=3.52 (yr -1), Z=4.19 (yr -1), and E=0.85, respectively. Exploitation rate (U), 0.53, annual total stock at the beginning of the year (Bv), 32264 t, Annual average standing stock (B), 4827 t, Maximum Constant Yield (MCY),10260 t, maximum sustainable yield (MSY),15390 t, fishing mortality rate that maximizes equilibrium yield per recruit, Fmax: 0.8 and Exploitation ratio maximum sustainable yield, Emsy: 0.54 were calculated for this species. Results of this study showed exploitation ratio of the Largehead hairtail stock is overfishing and decreasing of exploitation rate proposed.
