Al-MazrouiA. 3201163The present study was carried out to determine the mortality parameters, stock status and potential management of large head hairtail, the Trichiurus lepturus, Fisheries in the Arabian Sea. Length cohort analyses and yield per recruit were performed by simulating changes in fishing effort, in first catch length and closing season for trawlers. To carry out this analysis a data base including biological parameters, length frequency distributions and catches of Trichiurus lepturus in Oman according to fleet components has been established. Exploitation parameters of this species such as fishing mortalities and yield per recruit were estimated through the ANALEN software while natural mortality was calculated using Pauly equation. The results showed that: (1) the average fishing mortality rate is relatively high (0.5), but acts in majority on the adult fraction of the stock. The exploitation pattern differs, however, among fleets with some fleet components fishing in part immature Largehead hairtail (trawlers) and others largely the adult fraction of the stock (gill nets and hand lines). (2) An increase in total fishing effort would not lead to a significant long-term gain in total catch but the spawning stock biomass would decrease. This measure affects differently the fleet components. (3) A moderate increase of minimum length limit in catches would not affect, significantly, the long term yield and the stock spawning biomass. (4) A significant long term gain would be obtained when closing season (for trawlers) is regulated during April-June.]]>Abdussamad, E.M., P.N.R. Nair and P.
