中文摘要 | 台灣?仔漁業問題並非資源本身的問題,而是因引進?仔雙拖網漁具 漁法所衍生之問題。由於該漁具網目過密且漁獲效率高,不但傷害許多經濟性 魚類的仔稚魚,同時,因大量捕撈?仔魚,導致大大減少了年齡未滿一歲之鱙 魚資源量。年齡未滿一歲的鱙魚,在沿岸漁業扮演著兩種十分重要的角色,其 一為中、大型魚類的餌料,其二則為來年?仔的種魚。當長年捕撈作業,使該 年齡群級魚消失後,起食物鏈斷裂,而導致沿岸漁場衰退等因素,引發現今種 種的漁業問題;因此,惟有逐漸減少雙拖網漁具漁法或採用相當的補救管理方 法。這些方法包括:一、?仔體長限制及漁獲量限制,二、調整目前之?仔魚禁 漁期,三、小資源群經營與管理,四、組織產銷班,五、建立證照制度等。這 五種保護方法的同時進行,預估將可解決目前沿岸漁業所面臨之問題。 |
英文摘要 | The anchovy larval net was introduced to Taiwan in 1977. Due to the small mesh size and the highly fishing efficient, the larvae and juveniles of anchovy and many other demersal fishes were caught in a great amount. As a result, many problems of coastal water fisheries were arised. The following measures are suggested to solve the engraulid Larval fisheries problem: (1) to reduction effort, the number of larval anchovy net, (2) to limit the amount of total catch, fish size and fishing season, (3) to organize the production and market groups amoung fishermen, (4) to set up a license system of fishing, and (5) to manage the stock. |
