Fluctuation in Ommastrephe bartrami yield in the North Pacific

The fluctuation in Ommastrephe bartrami yield from 1995 to 2001 in the North Pacific was shown obvious, on which this study was conducted using data of sea surface temperature （SST）, chlorophyll-a （chl-α） and statistical production. The study shows that, cool water and low food abundance caused by abnormal Kuroshio resulted in the reduction in abundance of O. bartrami, which was worsened by excessive catch and the unawareness to local fishery resources protection.

在在北方太平洋的从 1995 ～ 2001 的 Ommastrephe bartrami 产量的变化被显示出明显，在哪个上这研究用海表面温度(SST ) 的数据被进行，叶绿素 -- 一(chl -- 一) 并且统计生产。丰富由反常自台湾东面的菲律宾海流向日本的暖流引起了的学习表演，凉爽的水和低食物在许多 O 导致了减小。bartrami，它被过多的钩子和不知道的海角变得更坏到本地渔业资源保护。
