中文摘要 | 為瞭解臺灣西部中區沿岸,仔稚魚在潮間帶上的組成型態,並比較河口域及平直岸 的群集差異,本研究以1990年3月至1991年2月間於麗水(大肚溪口)及王功(平直海岸),兩 測站採集一年的仔稚魚標本進行分析研究。 實驗區的背景因素,包括溫、鹽度、pH值及溶氧等水文因子。背景因子的統計分析顯示: 全年地域間之差異不顯著;但這兩個生態地理區,在魚種組成上,可以斷定為不同。 在河口域,共捕獲仔稚魚38種、4,603尾;黑鯛為主要種,佔18.4%;其餘依序為大鱗鯔 (16.0%),印度銀帶鰶(15.18%)及短鑽嘴魚(11.07%)。在平直岸,共捕獲53種、54,007尾仔稚 魚;眶棘雙邊魚為主要種,佔55.81%;其餘依序為黑鯛(19.2%),短鑽嘴魚(5.65%),?虎(5.47%) 及大鱗鯔(3.94%)。 在河口域,月別魚種的豐度在3-16個之間,個體出現之豐度以4至8月為最高,歧異度 在0.1737-0.8140間。在平直岸,魚種的豐度在4-27個之間,個體出現之豐度以4至7月為 年內高峰,歧異度在0.2443-0.8317間,平直岸的複雜度高於河口域。 在兩個不同的生態地理區,同種的大鱗鯔、花身雞魚及短鑽嘴魚其體長組成不同;但黑鯛 在兩區間,其體長組成無差異。 |
英文摘要 | To estimate the larval fish assemblage in the intertidal zone of the western coast of central Taiwan, two sampling sites were selected for representing estuary and plain coast. Species composition, monthly occurrence and size variation were measured. The differences between eco-geographic regions were compared. Environmental factors, such as water temperatures. Salinity, dissolved oxygen, and pH value were measured. No annual differences between eco-geographic types were found. On the other hand, the differences on the attribute of the assemblage could be confirmed. In the estuary, a total of 4,603 larvae assigned to 38 species was collected. Acanthopagrus schlegeli was the most abundant species which counted to 1834% of total catch. The remaining dominant species were Liza macrolepis (16.01%), Stolephorus indicus (15.18%), and Gerres abbrevidtus (11.07%). In the plain coast, a total of 54,007 larvae assigned to 53 species was sampled. Ambassiss gymnocephalus was the most abundant species which was counted to 55.81% of total catch. The leftover dominant species were A. schlegeli (19.2%), G. abbreviatus (5.65%), gobiid (5.47%), and L. macrolepis (3.94%). A significant difference in species composition was found between assemblages of estuary and plain coast. In the estuary, monthly richness of species ranged 3-16 taxa. The larval assemblage indicated a higher abundance from April to August. The monthly diversity index of estuary assemblage ranged 0.17-0.81. In plain coast, monthly richness of species ranged 4-27 taxa. The larval assemblage indicated higher abundance from April to July. The monthly diversity index of plain coastal assemblage ranged 0.24-0.83. Four major species were selected for comparison on monthly size variation between eco-geographic types. Differences were found on L. macrolepis. T. jarbua, and G. abbreviatus, but not on A. schlegeli. |
