Abstract

The aim of this study was to analyze the population of Silver pomfret, using fishing data in the Persian Gulf and Oman Sea waters. Sampling was done using trawl net, gill net and set net (Moshta) for 12 months, from April to March 2019. A total of 955 specimens were examined and 565 fish were split. In order to calculate the required parameters in the model, sex studies, reproduction, growth and mortality of this species were studied. In order to analyze the population of silver pomfret, first the definitive analysis method was performed. Uncertain model simulation was performed by Monte Carlo simulations because the results of the definitive simulation model cannot be relied upon much. The Ricker equation was used to investigate the requitment- stock relationship. Stock Reduction Analysis (SRA) was utilized to determine the catch trend and stock biomass of silver pomfret in the future. SRA analysis revealed that if the present increasing trend of fishing effort continues, if adjusting strategies is not taken and if unauthorized fishing is not forbidden, the stocks of this valuable species would be reducing and It will reach the lowest level (148 t) in 2071.
