水產研究(1993年創刊)-2008年澎湖寒害對海域內浮游性橈足類群聚之影響
主題: 2008年澎湖寒害對海域內浮游性橈足類群聚之影響
摘要(中):
冬季期間大陸沿岸流冷水由東海向南流經台灣海峽,並受黑潮支流暖水阻擋於澎湖西側海域。但2008年2月期間受大陸冷氣團南下影響,大陸沿岸流向東南海域推進,涵蓋澎湖附近海域,使得青灣內海水溫度於本研究期間較往年約下降3.5 ℃。本研究調查期間共記錄橈足類84種,分屬2目23科38屬,前5種主要優勢種類包括瘦尾胸刺水蚤 (Centropages tenuiremis)、針刺擬哲水蚤(Paracalanus aculeatus)、麗隆水蚤 (Oncaea venusta)、錐形寬水蚤 (Temora turbinata) 及長尾基齒哲水蚤 (Clausocalanus furcatus)。群集分析結果顯示,青灣海域內外之橈足類組成有明顯之差異,其中瘦尾胸刺水蚤於寒害次月大量出現於該灣內海域。青灣屬半封閉海域,其灣內海水交換速度低於灣外海域,因此,灣內海域之橈足類組成於寒害後連續 2 個月期間有明顯差異,而灣外海域受寒害之影響相對較小。

摘要abstract(英): The cold China Coastal Current flow from the East China Sea southward into the Taiwan Strait in winter and it is usually blocked by the warm Kruoshio Branch Current in the western water of Penghu. In February 2008, a China cold air mass intruded southeastward into the surrounding waters of Penghu unexpectedly. This cold accident caused a 3.5 ℃ drop in water temperature in the station A inner the Chingwan bay of Penghu in contrast to the same month of pervious year. There were 84 species of copepods and belonged to 2 orders, 23 families, and 38 genera in this study. The first five dominant copepods were Centropages tenuiremis, Paracalanus aculeatus, Oncaea venusta, Temora turbinata and Clausocalanus furcatus. The cluster analysis showed that copepod compositions at those stations inner the bay were significant differences with stations outside the bay. The Chignwan bay is a semi-closed bay and the rate of water change in the inner bay is slower than that in outer bay. The cold accident resulting from the intruding of China Coastal Current clearly changed the copepod compositions of Chingwan bay in the following two months.
