中文摘要 | 著者擬定一系列的研究,企圖對宜蘭灣內的?鱙魚資源特性進行瞭解,以期做為漁業及海洋生態系管理之依據。本次報告描述漁期、主要魚種及體長之季節變化。 本年有兩個漁期,其一為7月至11的秋季漁期,產量高峰為九月時之月產量125,060公斤;另一漁期為3月至6月時的春季漁期,於四月達107,553公斤之高峰。本漁場之漁獲對象有三種輪流形成主要漁獲物;即春季漁期由日本鮆(Engraulis japonicus)構成。秋季漁期則先由異葉銀帶鰶(Encrasicholina heteroloba)為主,再由左氏銀帶鰶(Encrasicholina puntifer)構成。日本鮆的體長範圍在12.7-29.77 mm之間,每?之平均體長由17.2-23.7 mm不等;左氏銀帶鰶則為11.4-41.7 mm及18.0-22.4 mm組成;異葉銀帶鰶則為11.0-30.3 mm及15.4-18.4 mm所組成。 |
英文摘要 | A series of project focused on the biology of herring-like fish (HELF) resources in the I-Lan Bay was planned to elucidate its characteristics under the impact of heavy fishing. This report describes the fishing season, major species and size variation of the catches of the HELF fishery in 1991-1992 fishing seasons. In 1991-1992, two fishing seasons are distinguished, the first season started from July to November with a peak estimated catch of 125,060 kg in September and the other from late March to June with a peak of 107,553 kg in April. Three herring-like larval fishes alternatively supported the year-round fishing activities: Engraulis japonicus, Encrasicholina punctifer and Encrasicholina heteroloba. During the period of the fist fishing season, the stocks were composed of E. heteroloba and E. punctifer, whereas E. japonicus in the second season. The length of E. japonicus was in the range 12.7-29.7 mm, average 17.2-23.7 mm; E. punctifer range 11.4-41.77 mm, average 18.0-22.4 mm; E. heteroloba range 11.0-30.3 mm, average 15.4-18.4 mm. |
