中文摘要:
      根据2004-2015年8-10月西北太平洋150°E~165°E和39°N~45°N海域的柔鱼(Ommastrephes bartramii)捕捞数据,分析了柔鱼渔场重心的年际和季节变化及其与海洋环境的关系,评估异常气候事件对柔鱼渔场海表面温度(SST)及渔场重心时空分布的影响。研究发现:8-10月柔鱼渔场适宜SST范围为13~22℃,且随着月份的增加而减小;渔场重心的年际和季节性变化显著,且季节性变化与柔鱼的洄游路线一致;各月份渔场重心的聚类结果均分为3类,分别对应正常气候条件、拉尼娜现象和厄尔尼诺现象;异常气候现象通过调控柔鱼渔场的适宜海表面温度范围,驱动渔场重心沿东北-西南方向移动:厄尔尼诺现象发生时,渔场SST降低,渔场重心向西南方向偏移;正常气候和拉尼娜现象发生时渔场SST升高,渔场重心向东北方向移动。
英文摘要:
      The fishing data of O.bartramii from 150°E -165°E, 39°N-45°N in the northwestern Pacific Ocean from August to October from 2004 to 2015 were used. The interannual and seasonal variations of gravity centers of the fishing ground and its relationship with marine environment were studied. The influences of abnormal climatic events on sea surface temperature (SST) and the fishing ground's gravity centers were evatuated. It was found that the appropriate SST range of fishing ground for O. bartramii is 13-22℃, which decreased month by month. The interannual and seasonal variations of gravity centers of the fishing ground were significant, and the seasonal variation is consistent with the migration route for O. bartramii. The clustering results of the center of gravity of fishing grounds in each month are divided into three categories, which corresponded to normal climatic conditions, La Niña events and El Niño events, respectively. Abnormal climatic events change the range of cold and warm water in the fishing ground of O. bartramii, thereby changing the distribution of the appropriate temperature range, and eventually moving the gravity centers of the fishing ground along northeast-southwest direction. When the El Niño events occurred, SST in the study areas decreased and the gravity centers of the fishing ground shifted to the southwest. When normal climate conditions and the La Nina events occurred, SST in the study area increased and the gravity centers of the fishing ground shifted to the northeast.
