摘　　要：阿曼湾海域是我国新开发的过洋性渔场之一,根据2016年我国底拖网渔船在阿曼湾深水海域生产调查数据,分析该海域我国底拖网作业渔场分布、渔获物组成以及主捕种类的开发现状,为阿曼湾深水渔场渔业资源的可持续利用提供参考。研究结果表明,阿曼湾深水渔场主要分布在N 25°25′~25°40′,E 57°00′~57°25′的200 m以深海域;渔获物种类共29种,主要经济种类为带鱼、海鳗和大眼黑姑鱼。2016年带鱼的单位捕捞努力量渔获量为3.89 t/d。渔汛旺期为1—3月和10—11月,3月带鱼单位捕捞努力量渔获量最高(5.57 t/d);淡季为12月和4—6月,4月带鱼单位捕捞努力量渔获量最低(1.00 t/d)。分析认为,阿曼湾深水渔场狭窄,渔船容纳量有限。建议未来我国渔船在中伊渔业协议的框架下入渔,严格控制入渔指标,有序地推进伊朗阿曼湾海域渔业资源的开发与利用。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.
