Abstract：The Gulf of Oman is one of new fishing grounds for distant-water fishery of China. Fishing ground distribution of bottom trawler, catch composition and development status of main species were based on fishing production data from bottom trawlers in the Gulf of Oman of Iran in 2016, which provided references for the sustainable utilization of fisheries resources in the deep waters of the Gulf of Oman. The results showed that the deepwater fishing ground was mainly distributed in N 25°25′—25°40′,E 57°00′—57°25′. Twenty-nine species were identified in the catch composition and the main target species were hairtail Trichiutus lepturus, conger pike Muraenesox cinereus, and blackmouth croaker Atrobucca alcocki whose size was generally large. The catch per unit effort (CPUE) of hairtail was 3.89 t/d in 2016. The high fishing season was observed from January to March and from October to November, with the maximum CPUE of 5.57 t/d for hairtail, the off-season was December and April to June, with the minimus CPUE of 1.00 t/d hairtail in April. However, at present the deep water fishing ground of the Gulf of Oman was narrow and fishing effort was limited, the Chinese fishing vessels must have access fishing in the fishery in the framework of China-Iran fishery agreements. Meantime fisheries resources will be reasonably and orderly developed and utilized in the Gulf of Oman in the future, and the number of fishing vessel must be strictly controlled.
