中文摘要為了解台灣沿岸海域仔稚魚之群聚構造，以建立仔稚魚多樣性資料庫，作為仔稚魚資源量評估之基礎以及環境監測和海洋保護區劃設之參考，自2004年起在台灣沿岸海域的60個測站，以海安號或海建號試驗船使用丸氏仔魚網進行水表層水平拖曳，來執行為期4年、每季一航次的環島調查。在2004年5 、8 、11月和2005年1月的4個航次，共計採獲197,908粒的魚卵和分屬於84科136類的仔稚魚6,531尾。經聚類分析的結果顯示，不同季節的仔稚魚群聚受到台灣周邊水團變動的影響，各分為數個不同地理群， 且優勢種也都不同。

To clarify the dynamics of larval fish assemblages in the coastal waters off Taiwan, a 4 years study is conducted by season in the 60 stations of the area. A total of 6,531 larvae representing 136 taxa and 84 families as well as 197,908 eggs were caught from 4 seasons of 2004-2005. Based on the Bray-Curtis similarity indices and clustering analysis, 2, 2, 2, and 5 geographic groups of larval fish assemblages were found in spring, summer, autumn and winter in the coastal waters off Taiwan, respectively. These groups represented the Kuroshio Current and its branch, as well as Coastal Current of China. These assemblages were comprised different species and reflected different origin of them.
