Extreme heat: Environment Agency calls on public to help protect fish

Environment Agency officers are on the ground protecting fisheries across England as temperatures soar

by Angling Times |

With a rare Red Extreme Heat Warning issued by the Met Office for Monday 18 July and Tuesday 19 July, the Environment Agency is calling on anglers, fisheries owners and the public to help them protect vulnerable fish stocks.

Extreme weather, including continuous hot temperatures and thunderstorms, can be highly dangerous for fish and can cause a range of problems, particularly for more susceptible species like salmon and pike. Hot and sunny weather typically triggers algal blooms, which can reduce dissolved oxygen levels in our waters leading to fish becoming distressed and, in some cases, dying.

In the last week, Environment Agency officers have helped protect thousands of fish in Worcestershire and Essex thanks to anglers fisheries owners and the public report concerns to our Incident Hotline on 0800 80 70 60 or alerting the fishery owner or angling club.

Fish should never be moved to other waters by the public because they are unlikely to survive and could spread disease or invasive species by accident, which can damage fish and other wildlife in the area.

Heidi Stone, Fisheries Partnerships Manager at the Environment Agency, said:

“Environment Agency teams are working hard to mitigate the impacts of recent high temperatures and are monitoring the situation closely when it comes to protecting fish at risk.

“We aim to respond to reports of fish in distress as quickly as possible. Help from the public goes a long way which is why we provide free advice to all on how to protect fish during hot weather.”

Last week in Worcestershire, the Environment Agency deployed several aeration pumps to an angling club’s fishery after dissolved oxygen levels fell to around 15 per cent. This rapid response saved thousands of vulnerable fish and averted a significant fish mortality. At another fishery in Basildon, Essex, Environment Agency officers deployed aerators after the report of 1,000 dead fish at a fishery owned by the borough council. Dissolved oxygen levels have since recovered due to prompt reporting and a rapid response from EA fisheries officers.

Environment Agency incident response work includes deploying aeration equipment or hydrogen peroxide to restore dissolved oxygen levels, providing expert advice to angling clubs and anglers, and occasionally, as a last resort, relocating fish. All of this work is funded by fishing licence income – and provides a vital life line to fisheries when they most need it.

Many angling clubs and fisheries carry out effective practices to help manage and mitigate the impacts of continued hot temperatures on fisheries, but a list of ten top tips are available to guide people on how to protect vital stocks and prevent fish deaths where possible.

Anglers can also help vulnerable fish stocks by minimising use of bait, taking care when playing, landing and releasing large or sensitive fish, such as pike, barbel, trout and salmon, as well as avoiding taking photos of fish out of water to avoid further oxygen loss.

Anyone who sees fish in distress should contact the Environment Agency on 0800 80 70 60.
