一份報告警告說，淡水魚的數(shù)量將出現(xiàn) “災(zāi)難性” 下降，近三分之一的淡水魚面臨滅絕的威脅。

More than half the world's fish are found in lakes, rivers and wetlands – from carp and minnow to giant catfish.

世界上超過一半的魚類都生活在湖泊、河流和濕地中，從鯉魚、米諾魚到巨型鯰魚，種類繁多。

They face a number of threats including pollution, unsustainable fishing, and the damming and draining of rivers and wetlands.

這些魚類面臨多種威脅，包括污染、竭澤而漁式的捕魚、河流與濕地的筑壩和排水。

Conservation groups say 80 species are known to have become extinct, 16 in the last year alone.

保育組織稱，目前所知已經(jīng)有80個淡水魚物種滅絕，僅去年一年就有16個。

In UK waters, the sturgeon and the burbot have vanished; salmon are disappearing, and the European eel remained critically endangered.

在英國水域，鱘魚和江鱈已經(jīng)絕跡；鮭魚正逐漸消失，而歐洲鰻鱺仍處于極度瀕危狀態(tài)。

According to the WWF, much of the decline is driven by the poor state of rivers – mostly as a result of pollution, dams and sewage.

世界自然基金會指出，造成數(shù)量下降的主因是河流狀況不佳，這主要歸咎于污染、筑壩和污水排放。
