日月潭剋菜蛤放養9.3萬尾魚苗

日月潭外來魚種破壞生態，台電大觀電廠為減少淡水貽貝滋生影響發電並兼顧生態平衡，昨在日月潭放養9萬3000尾魚苗，包含烏鰡、鯁魚、曲腰魚（俗稱總統魚）等，透過生態防治清除貽貝，回復魚類生態，增加漁民收益。

日月潭漁會總幹事張乾任說，20年來日月潭被放生團體野放外來魚種如紅魔鬼與珍珠斑、玻璃魚等，其中紅魔鬼與珍珠斑還可以抓來煮食，但外來魚種領域性強，破壞原有魚類生態。

台電大觀電廠昨天準備4萬尾烏鰡、2萬1000尾鯁魚、1萬尾曲腰魚及2萬2000尾大頭鰱魚，由副廠長蘇漢敦、張乾任、魚池鄉長陳錦倫等人在朝霧碼頭放流。

蘇漢墩說，電廠從79年起，每年在日月潭放養魚苗，主要是因俗稱「菜蛤」的淡水貽貝附著生長在電廠取水攔汙柵，影響發電取水效率與設施安全，才決定放養可剋制菜蛤的天敵魚類。

廠方指出，近年來大觀電廠投入復育及魚苗放養，增加曲腰魚等種類，有助於平衡日月潭生態，也呼籲漁民與釣客一旦捕獲魚苗，能放回潭中，讓牠們繼續成長，才能兼顧環保與經濟效益。
