爲瞭解鰹鮪類幼生在黑潮流域的初期成長與輸送過程以作為資源評估之參據，於2013年5月8-18日間在台灣周邊海域的62個測站使用水試二號試驗船以ORI浮游動物採集網進行鰹鮪類幼生之採集，結果顯示黑鮪和長鰭鮪僅少量分布於台灣東部黑潮流域，大目鮪和黃鰭鮪出現在東北和西南部的黑潮水域，而豐度最高的圓花鰹則分布於東北和西南部的黑潮和冷水塊的鋒面區。以上的結果顯示，鮪類幼生確實是棲息在黑潮水域中，但也造成它們的豐度不高的事實，而豐度相對較高的海域則可能存在有地形性湧升或是沿岸水影響所及的地方；圓花鰹幼生則顯然是利用冷暖水團交會的海洋鋒面區作為哺育場，因而有較高的豐度存在。

To clarify the distribution of larval tunas and bonitos in the Kuroshio waters off eastern Taiwan, the larvae were collected from 62 stations in the period from May 8 to 18 by R/V Fishery Research Ⅱ with ORI net. Among them, Thunnus thynnus and T. alalunga distributed in the Kuroshio waters off eastern Taiwan, T. obesus and T. albacares also occurred in the Kuroshio waters off northeastern and southwestern waters of Taiwan. In contrary, much abundant species, Auxis rochei were abundant in the front of Kuroshio and cool waters.
