This is the world's largest freshwater fish ever documented.

這是有記錄以來，世界上最大的淡水魚。

The 300kg stingray was caught in Cambodia's Mekong river.

There is no official database for such a find.

目前沒有記錄世界上最大淡水魚的官方數(shù)據(jù)庫。

But scientists are excited by the discovery, saying it offers hope at a time when overfishing, dams and pollution are a threat.

但科學(xué)家們對(duì)這次湄公河中發(fā)現(xiàn)的巨大黃貂魚興奮不已，他們表示，當(dāng)下，過度捕撈、筑壩和污染對(duì)河流生態(tài)環(huán)境構(gòu)成了威脅，這個(gè)發(fā)現(xiàn)帶來了希望。

The stingray was fitted with an acoustic tag to track its future movements.

科學(xué)家在黃貂魚身上安裝了一個(gè)聲學(xué)標(biāo)簽，跟蹤它未來的活動(dòng)。

It was then released back into the river.

這條黃貂魚之后被放歸河里。
