中文摘要 | 本研究西南部竹坑滿豐定置網漁場為調查對象,利用漁獲統計、現場海況觀測、 衛星海面水溫影像、氣象資料等究明巴鰹漁獲量之變動與海況和氣象因子間之關係。 巴鰹終年可漁獲,主要漁期在十月至翌年四月,但在最冷的月別裡漁獲量甚差。近十年巴鰹 之年產量有逐漸減少的趨勢。冬季期間,暖水舌向沿岸侵入時,巴鰹隨其大量游向沿岸海域 ,當暖水舌經過定置網期間,巴鰹漁獲量顯著增多。雖然如此,唯有暖水舌經過定置網且天 氣條件良好 (氣溫 > 19 ° C 且風速 < 5 m/sec) 時,方能出現巴鰹的豐漁。 |
英文摘要 | The catch fluctuation of oceanic bonito (Eughynnus af finis) in relatio n of oceanic and meteorolgical factors was studied at the Mang-Fong set-net fish ing ground in the Jwu-Keng coast on southwestern Taiwan, on the basis of its catch statistics, oceanic conditions, satellite temperature mapping and meteorological information for 1991 to 1994. The oceanic bonito were caught throughout the year. The main fishing period was between October and April, with the poorest catch in the coldest months. In the last decade, the catch of oceanic bonito decreased year after year. In winter, when warn water tongue flew through the position of the set net, the catch would increase greatly. Both good oceanic and weather conditions (air temperature > 19 ° C and wind speed < 5 m/sec) were required for a good catch of oceanic bonito. |
