Low oxygen levels and hot weather are believed to have killed thousands of fish in Perth's Swan River.
低氧氣水平和炎熱天氣被認為已殺害數千珀斯天鵝河的魚兒。
About 5,000 dead fish were discovered between the Middle Swan Bridge and the Ellen Brook in the upper reaches of the river.
約5,000死魚被發現在中天鵝橋和在河的上游艾倫布魯克之間。
Swan River Trust spokesman Mark Cugley says recent rain and hot weather have decreased oxygen levels in the waterway and that particular area is outside the reach of the river's oxygenation plants.
天鵝河基金發言人馬克 Cugley說，最近的雨水和炎熱天氣減少水路中的含氧量，及特別是河流的充氧植物地帶外的區域。
"Sudden rainfall often drags nutrient-rich organic matter into the river and this typically causes oxygen levels to rapidly drop below levels suitable for fish and other aquatic fauna," he said.
“突如其來的降雨往往拖拉營養豐富的有機物質進入河中，和這典型地導致含氧量迅速下降，到低於適合魚類和其它水生動物的水平，”他說。
"It is something that is of a concern, and although we believe the cause was low oxygen levels in the water column, we are monitoring the water quality and sending off samples of those fish for that to be clarified."

Mr Cugley says most of the fish appear to be juvenile black bream with the remainder being trumpeter.
