利用黑潮西边界流影响下的沿岸水温，研究了日本鳗鲡（Anguilla japonica）玻璃鳗补充量的可预测性。1971-2014年，日本滨名湖河口的玻璃鳗鱼捕捞量与两个沿海站点（白滨湖和滨名湖）之间的平均水温差（WTD）进行了比较。年际变化的方向（即，结果表明，在1995-2006年的12年中，黄鳝渔获量与WTD呈显著正相关（r= 0.68，p = 0.0150）。在研究期间（1971-2014年）的渔季，WTD与黑潮路径最南端的纬度相关（r= 0.40，p = 0.0068）;因此，WTD似乎反映了黑潮路径的波动和来自西边界流的暖水入侵。玻璃鳗鱼渔获量和WTD的年际变化之间的匹配方向的比例为0.71的非曲流（近岸）路径年（显着高于0.5，匹配的迹象，由于机会的预期比例，p= 0.0448），而它是0.46的曲流（离岸）路径年（，p= 0.6526）。因此，WTD的年际增加/减少的趋势与河口补充A。当黑潮以非蜿蜒路径流动时，日本玻璃鳗鱼。日本鳗鱼的这种环境-补充关系（西部边界电流-补充联系）表明了对沿海沃茨进行持续环境监测的重要性。
Predictability of glass eel recruitment of Japanese eel (Anguilla japonica) was examined with a simple indicator constructed using coastal water temperature under the influence of the western boundary current, the Kuroshio. The 1971–2014 glass eel catch from an estuary, Lake Hamana, Japan, was compared with the mean water temperature difference (WTD) between two coastal sites, Shirahama and Lake Hamana, during the glass eel fishing season. The directions of interannual change (i.e., increase/decrease) in the glass eel catch and WTD fully synchronized for 12 consecutive years (1995–2006), and these variables were positively correlated (r= 0.68,p= 0.0150). The WTD was correlated with the southernmost latitude of the Kuroshio path (r= 0.40,p= 0.0068) in the fishing season of the study period (1971–2014); therefore, the WTD appeared to reflect the path fluctuations of the Kuroshio and the warm water intrusions from this western boundary current. The proportion of matching directions between the interannual changes in the glass eel catch and WTD was 0.71 for the non-meander (nearshore) path years (significantly higher than 0.5, the expected proportion of matching signs due to chance;,p= 0.0448), whereas it was 0.46 for the meander (offshore) path years (,p= 0.6526). Thus, the WTD tends to interannually increase/decrease with the estuarine recruitment ofA. japonicaglass eels when the Kuroshio flows with non-meander paths. This environment-recruitment relationship (western boundary current-recruitment link) in the Japanese eel demonstrates the importance of continuous environmental monitoring of coastal waters.
