Abstract

The fishery of Omani sea cucumber, Holothuria scabra , is limited so far to the Mahout Bay in Al Wusta governorate. This fishery supports an uncertain number of fishermen ranging from 100 to 150. This fishery is not well-studied and has no current management program. In order to prepare a management strategy, the government has suspended this fishery for 2 years from March 2018 to March 2021. Apart from presenting a thorough review on the sea cucumber fishery in Oman, the current work presents a detailed analysis of the length–weight relationship, sex ratio, and condition factor of the H. scabra collected from four different areas during the period February-May 2019. Based on the results, the females were longer than males, that is 226±33.4 and 221±37.8 mm, respectively. The overall sex ratio of the entire/pooled sample was 0.49 which was not different from the anticipated theoretical sex ratio of 0.5. The mean K n and the empirical weight–length equations for the total sample were between 0.12±0.01 and 1.0±0.16, and W =0.03L 1.6 , respectively.

阿曼沙鱼海参，Holothuria scabra Jaeger, 1833 (Holothuria holothuridae: Holothuriidae):渔业，长-重关系和条件因素

阿曼海参(Holothuria scabra)的捕捞迄今仅限于Al Wusta省的Mahout湾。这个渔场支持的渔民数量不确定，从100到150人不等。这种渔业没有得到很好的研究，也没有目前的管理方案。政府为了制定经营战略，从2018年3月开始到2021年3月，将暂停捕捞2年。除了对阿曼海参渔业进行全面回顾外，目前的工作还详细分析了2019年2月至5月期间从四个不同地区收集的海鞘鱼的长度-重量关系、性别比例和条件因素。结果显示，雌性比雄性长，分别为226±33.4 mm和221±37.8 mm。整个/合并样本的总体性别比为0.49，与预期的理论性别比0.5没有差异。总样品的平均K n和经验权长方程分别在0.12±0.01 ~ 1.0±0.16之间，W = 0.031 l 1.6。
