Fishing event improves Sutton Bingham Reservoir’s ecosystem
Over a seven-day period, around 100 anglers removed coarse fish from Sutton Bingham Reservoir, helping to improve its ecosystem and water quality.
Braving poor weather conditions, some anglers caught 25 to 30 carps a day, with bags weighing in at up to 120 pounds. The fish were later transported to a registered fish farm.
Why did we hold the event?
Over the past few decades, it has been observed that the reservoir’s aquatic ecosystem, which was once dominated by macrophytes (larger aquatic plants), has become eutrophic and dominated by phytoplankton (more microscopic plants).
There are several contributing factors to this change in the ecosystem, including rising levels of nutrients from the land management practices used in the catchment upstream, the addition of water pumped from the River Yeo and the presence of coarse fish.
In turn, the changing ecosystem has negatively affected food sources for a range of wildlife, which meant action had to be taken to support these animals.
How will the event benefit the reservoir?
The event involved removing a huge number of coarse fish from the reservoir, allowing us to actively manage populations.
The removal of the coarse fish, in combination with work we are carrying out in the catchment upstream of the reservoir, will improve the habitat value and reduce nutrients in the water.
In the near future, this will hopefully encourage the return of wildfowl and other animals which have declined in recent decades.
