In an effort to remove competition for space, food and available oxygen for native fish, around 125,000 juvenile carp have been removed from near the Lake Pamamaroo Outlet during a five-day blitz by DPI Fisheries across four days.
The fish were caught and removed between April 24 and April 28.
While oxygen levels have improved since the major catch, the level of improvement varies in different parts of the Darling-Baaka River, says the latest report this week from WaterNSW.
Water quality monitoring this last week has shown good levels of dissolved oxygen during the day in most parts of the Menindee reach.
The significant number of native Bony Herring in the river system are still causing issues with available oxygen, but WaterNSW believes there are enough strong areas of dissolved oxygen in the river to provide refuge for the native fish.
Despite the good news, another fish kill event is possible, likely due to stress, says the update. Regular monitoring continues in a bid to minimise the risk of water quality deteriorating in different parts of the river.
Recent drinking water testing by Essential Water (EW) has confirmed it’s safe to drink.
EW has stepped up its sampling and testing efforts to guarantee compliance with the Australian Drinking Water Guidelines and to enable prompt action if a supply switchover becomes necessary.
