Australia: Thousands of fishes die as rains wash bushfire ash into rivers

Hundreds of thousands of fish have been reported de in New South Whales by recreational fishermen. Reports suggest that ash and mud from bushfire-affected areas have been washed into rivers due to recent rains in Australia. Scientists believe that it will take years for fish populations to recover.

Suffocating fish

NSW Department of Primary Industries has allegedly received dozens of reports about thousands of de fish in rivers since December last year. While talking to local media, an ecologist has said that de fish will impact fish population for deces to come. An example of species of fish that have been hit hard is Australian bass.

Locals from New South Wales have reported that rains in past 10 days have dumped even more ash and mud from bushfires into river. According to Larry Newberry, a recreational fisher from Frederickton, ash and mud from rains have, in his opinion, killed every fish in a 100 kilometre stretch of river. He also ded that he h never seen a 'fish kill' of this magnitude ever before and would probably be replicated in every east coast river in New South Wales.

species that have reportedly been affected are Australian bass, eels, bullhe mullet, yellow-eye mullet, herring, gudgeons and catfish. According to Prof Lee Baumgartner, a freshwater ecologist at Charles Sturt University, reason that fish died is that y suffocated. 

ash in water promotes bacteria in water that decreases oxygen content and if water becomes sludgy n fish are unable to pass eugh water across ir gills to successfully extract eugh oxygen.  De fish have also been reported at Tilba Lake on south coast of NSW.
