Environmental groups have been placed on stand-by to oxygenate England’s rivers in a bid to guard fish within the occasion of a heatwave.

The Environment Agency (EA) says it has recorded “hundreds of fish kill incidents” already this yr – with drops in oxygen ranges in rivers and canals blamed.

The EA says it has made its fisheries groups accessible “around the clock” to reply to fish kill incidents, together with utilizing aeration gear to assist restore the degrees of dissolved oxygen in rivers and canals.

The company is already investigating fish kill incidents at Salford Quays, Greater Manchester, and a stretch of the River Mole, in Surrey.

It believes excessive temperatures and low atmospheric strain because of thunderstorms – inflicting low dissolved oxygen ranges – are accountable.

However, the Angling Trust, which has obtained reviews of fish kill incidents within the North West, South West and South East of England, in addition to the Warwickshire Avon, warns such an strategy is “complacent”.

The belief says “poor water quality, pollution and, in places, over abstractions and low flows” are contributing to the incidents.

“While it may be the loss of oxygen that is causing the devastation, the blame does not lie solely with the hot weather,” the belief says.

“What we have is another wake-up call for the EA and Defra. These fish kills are yet more evidence of the appalling abuse our rivers face daily.

“As our local weather adjustments, our rivers merely wouldn’t have the resilience to operate in something like a pure freshwater ecosystem.

“A period of hot weather and thunderstorms is a tipping point, it is not the cause.”

The EA’s emergency plans had been mentioned on Wednesday at a gathering of England’s National Drought Group – which incorporates senior determination makers from the Environment Agency, authorities, water firms and key farming and environmental organisations.

The group heard how water ranges are at present larger than they had been this time in 2022 – the warmest yr on document within the UK.

“However, the natural environment continues to take time to recuperate from the impacts of last summer and the Environment Agency is also focusing ongoing efforts on monitoring how fish and invertebrates are recovering from drought,” the group mentioned in a press release.
