摘要
根据卫星遥感获取的海表水温和多年来我国在西北太平洋的柔鱼生产统计资料 ,探讨西北太平洋柔鱼渔场与水温分布特征。研究结果表明 ,15 0°E以西的柔鱼渔场 ,中心位置位于 4 1°N、14 6°E附近 ,渔场表层水温范围在 10～ 19℃之间 ,中心渔场表层水温为 13～ 18℃ ;15 0～ 16 0°E之间的柔鱼渔场 ,中心位置位于 4 2°0 0′N、15 5°0 0′E附近 ,渔场表层水温范围为 14～ 2 1℃ ,中心渔场表层水温约为 15～ 2 0℃。温度场特征分析显示 ,柔鱼中心渔场分布与冷水锋面、冷暖水切变锋面和暖水舌锋的变动密切相关。
Based on the data of surface water temperature obtained by satellite remote sensing and Chinese statistical data about squid (Ommastrephes bartrami) fishing yield in the Northwest Pacific Ocean, this paper studies on the relationship between the fishing ground distribution of Ommastrephes bartrami and water temperature.The research results showed that the central position of squid fishing ground located nearby 41° N and 146°E, the range of surface water temperature was between 10 ℃ and 19 ℃, and the optimum surface water temperature was between 13 ℃ and 18 ℃ in the west area of 150° E, and that the central position of squid fishing ground located nearby 42° N and 155° E, the range of surface water temperature was between 14 ℃ and 21℃, and the optimum surface water temperature was between 15 ℃ and 20℃ in the area of 150° E and 160° E.The characteristic analysis of temperature field indicated that the distributions of central fishing ground were closely in relation to the variety of cold water front, shearing front of cold and warm water and tongue front of warm water.
