[ 7 ] - Estimation of growth parameters and mortality rate of Upeneus sulphureus (Cuvier, 1829) in the Persian Gulf ecosystem

Population parameters were estimated for goatfish (Upeneus sulphureus, Cuvier, 1829) as a small size and abundant species in the Persian Gulf ecosystem. A method of Tropfish R package based on length frequencies analysis was used. A total of 520 fish samples were taken monthly from landing stations in the coastal area of Iranian Waters in the Persian Gulf (Bushehr coasts) from January 2017 to D...

[ 8 ] - Research Article: Life history traits of ribbonfish Trichiurus lepturus (Linnaeus, 1758) in the Persian Gulf and Oman Sea

Ribbonfish, Trichiurus lepturus (Linnaeus, 1758), is an important component of subsistence fisheries throughout its tropical and subtropical distribution. The catch rate of ribbonfish has increased seven-fold in a decade in the Persian Gulf and Oman Sea. We collected monthly biological samples from T. lepturus, to estimate growth and mortality parameters, and identify species reproductive patte...

[ 9 ] - Research Article: Length based spawning potential ratio (LBSPR) of javelin grunter, Pomadasys kaakan (Cuvier, 1830) in the Persian Gulf and Oman Sea

Length-Based Spawning Potential Ratio (LB-SPR) model was applied to describe the status of Javelin grunter, Pomadasys kaakan in the Persian Gulf and Oman Sea. From April 2002 to March 2019. 45,489 specimens were collected from fish landing sites monthly, and their length (FL) and weight were measured. The results of the present study showed that different gears captured most of the P. kaakan be...
