Mass Die-Off of Fish , Recorded in Australia's , Darling River.
Millions of dead fish
have been found in an Australian river.
NPR reports that government officials have said
that the cause is from dangerously low oxygen
levels in the water due to receding flood waters.
The dead fish were reportedly
discovered in the Darling River,
outside the town of Menindee.
According to government officials, the "ongoing"
event mainly involved bony herring, but also includes
murray cod, golden perch, silver perch and carp.
The Bony Herring species typically
booms and busts over time, Department of Primary Industries in New South Wales, via NPR.
It 'booms' in population numbers
during flood times and can then
experience significant mortalities
or 'busts' when flows return
to more normal levels, Department of Primary Industries in New South Wales, via NPR.

NPR reports that an extreme
heat wave has further exacerbated
oxygen levels in the river. .
The Associated Press originally reported in late
February that large numbers of dead fish had
been observed in the Darling-Baaka River.
Mass fish die-offs were also observed
on the river outside of Menindee amid
extreme droughts in late 2018 and early 2019.
