中文摘要 | 臺灣西區中發?仔漁業的漁場是由後龍溪口至大肚溪口的沿岸地帶。這個漁場的 主要漁獲物為五種鯷科魚類,即日本鯷(Engraulis Japonica, 28.1%)、芝蕪稜鯷 (Thryssa chefuensis , 21.1%)、杜氏稜鯷(Thryssa dussumieri , 17.9%)、島嶼小公 魚(Stolephorus insularis , 17.1%)、及刺公鯷(Encrasicholina punctifer, 7.8%)。本漁業一年內唯一的春-夏漁期,可以區分為五個階段,每一階段由一種鯷魚的仔 魚形成主要魚種。在每一階段中,鯷科魚類在魚種組成上至少佔83%以上。本報告簡要地描 述以上五種仔鯷魚在外部形態的不同,並整理出一個檢索表,以作為野外採樣時鑑定上的依 據。最後,我們討論了臺灣沿岸?仔漁業在時間及空間上的變異。 |
英文摘要 | The catch composition of the larval anchovy fishery in western central Taiwan is primarily composed of five engraulid species, Engraulis Japonica (28.1%), Thryssa chefuensis (21.1%), T. dussumieri (17.9%), Stolephorus insularis (17.1%) and Encrasicholina punctifer (7.8%). The spring-early summer fishing season, for E. japonica, T. chefuensis, T. dussumieri, E. punctifer and S. insularis, is divided into five different fishing periods. During this fishing season, five species alternate in forming the key component in the catch. During each fishing period, anchovy larva counts for at least 83% of the total catch. Distinctive external morphology of the five key species is briefly described in this study. A field key for identification of five species is established to facilitate later sampling procedures. Discussion involving the temporal and spatial variation of the larval anchovy fishery in Taiwan is included. |
