東引

〔記者俞肇福/基隆報導〕連江縣政府與台灣海洋大學合作,在馬祖東引鄉北海坑道進行小龍蝦與海參的復育、養殖作業,歷經七個月的努力,小龍蝦與海參的存活率與成長情況良好,小龍蝦已經成長到四百公克左右,海參也有八到十公分。

連江縣長劉增應表示,東引海域無污染且微生物多,水產資源豐富,是磯釣者的樂園,東引鄉昔日盛產龍蝦,曾有一張網捕捉到兩百多隻龍蝦的紀錄,但近年來龍蝦銳減,縣府與海大產學合作,啟動封閉十年的東引北海坑道,轉型為龍蝦與海參的養殖復育基地,去年十二月放養五到八公分、每隻約六十公克的四千隻小龍蝦苗,另外一千多隻放流在東引沿岸海域。

他說,小龍蝦人工培苗成功機率很低,軍方剛好釋出東引鄉北海坑道,縣府清除坑道底下淤泥,坑道口也築起可控制海水進出的阻隔牆,透過自然的海洋環境將北海坑道打造為龍蝦、海參的繁殖基地。

連江縣政府產業發展處長劉德全指出,今年初也投放約五百個海參(刺參)參苗在北海坑道養殖,存活率及生長情況都比預期更好,體長已達八到十公分左右,野生海參在台灣本島海域已不多見,因為台灣地處熱帶及亞熱帶海域,水溫高過攝氏廿五度就不適合養殖,東引北海坑道的海水冷涼,夏天水溫仍維持在攝氏廿度左右,較低的水溫提供海參生長的有利條件。
