Kuroshio Current and Japanese Pelagic Fisheries
黑潮与日本远洋渔业
精读先不看文字，完整听一遍。
-
The Kuroshio Current flows northward along Japan’s Pacific coast, transporting warm, nutrient-poor tropical water.黑潮沿日本太平洋海岸向北流动，输送温暖但营养贫乏的热带海水。
-
Where it meanders offshore, cold, nutrient-rich water rises near the Izu-Ogasawara Ridge to support plankton blooms.黑潮在近海蜿蜒时，寒冷且富含营养的海水在伊豆-小笠原海岭附近上涌，促进浮游生物大量繁殖。
-
These upwelling zones attract sardines, mackerel, and skipjack tuna, forming the backbone of Japan’s pelagic catch.这些上升流区吸引沙丁鱼、鲭鱼和鲣鱼，构成日本远洋渔业捕捞的支柱。
-
Fishermen track the Kuroshio’s seasonal shifts using satellite sea-surface temperature data and buoy networks.渔民利用卫星海表温度数据和浮标网络追踪黑潮的季节性变化。
-
The current’s western boundary intensifies eddy formation, creating temporary feeding hotspots that migrate yearly.黑潮西边界增强涡旋形成，产生每年迁移的临时渔场热点。
-
Overfishing pressure has increased as warming pushes species like Pacific bluefin tuna farther north into new zones.随着水温升高，太平洋蓝鳍金枪鱼等物种向北迁入新海域，过度捕捞压力随之加剧。
-
Coastal ports such as Kushiro rely on consistent Kuroshio-influenced currents to predict fish aggregation timing.钏路等沿海港口依赖稳定受黑潮影响的海流，以预测鱼类聚集时间。
-
Marine heatwaves linked to Kuroshio anomalies have recently reduced anchovy spawning success in the East China Sea.与黑潮异常相关的海洋热浪近期降低了东海鳀鱼的产卵成功率。
-
Japan’s exclusive economic zone extends 200 nautical miles, but stock migration crosses jurisdictional boundaries regularly.日本专属经济区延伸至200海里，但鱼类种群迁移频繁跨越管辖边界。
-
Fisheries scientists now model Kuroshio–Oyashio confluence dynamics to forecast annual catch potential for key species.渔业科学家正建模模拟黑潮与亲潮交汇动态，以预测关键鱼种的年度捕捞潜力。

课程开发中，敬请期待。成人和孩子都可以先自学听读、精读。
这边的讲解音轨还在做。想先跟着老师走完固定 30 课，可以去陈老师带读社（和自学通行不是同一份会员）。
