摘　　要：根据2010—2015年上海某远洋渔业公司在毛里塔尼亚的生产统计数据,结合卫星遥感资料,研究毛里塔尼亚海域底拖网头足类渔场与表温(SST)、海面高度距平均值(SSHA)、水深等海洋环境因子的关系。结果表明,头足类渔场分布与SST、SSHA、水深等因子关系密切,各月作业渔场的适宜环境范围有一定的差异;作业渔场分布在SST为15~28℃的海域,最适SST范围为16~22℃;作业渔场分布在SSHA为-50~10 cm的海域,最适SSHA范围为-20^-40 cm和-10~10 cm;作业渔场分布水深为10~90 m的海域,最适水深为50~70 m。The current study investigated the fishing ground distribution of bottom trawl fishery and its relationship with marine environmental factors based on the production statistics from Shanghai fishing company in waters of Mauritania during 2010 and 2015 and satellite remote sensing data including sea surface temperature（SST）and sea surface height anomaly（SSHA）. The results indicated that the fishing ground distribution is closely related to marine environment factors such as SST,SSHA and water depth,and that the suitable range of marine environment factors are variable among different months. The fishing grounds were distributed in waters of SST ranging from 15 to 28 ° C,and the optimum range of SST was 16–22 °C. The fishing grounds were located in the waters of SSHA with the value of-50 – 10 cm, and the optimal scope of SSHA was-20 –-40 cm and-10–10 cm. The fishing grounds were distributed in the waters of the depth of 10 – 90 m, and the optimal depth was 50 – 70 m. These results will improve the production for Mauritania bottom trawlers.
