Commercial carp set to be swimming in blue water this summer

It’s bright, it’s blue, and it could be coming to a venue near you this summer. A radical dye, which is being heralded as a miracle cure for excessive weed growth and fish-killing algal blooms, is set to become an increasingly common sight at commercial carp and mixed species fisheries.

This follows the Government’s decision to ban more conventional weedkillers used by fisheries in a month’s time.

The two dye-based products – Dyofix Pond Blue and Lake Shadow – which kill underwater plants by blocking ultraviolet light and preventing photosynthesis could be just what fishery managers need to prevent excessive weed growth and ensure waters remain fishable all year round.

Increasing concerns over the ban on traditional weedkillers mean the two ground-breaking products are set to be trialled by the Environment Agency.

“I get a lot of requests for weedkillers and queries about what people can use safely,” explained EA fisheries technical officer Paul Wilkanowski.

“I’ll be trialling Dyofix Pond Blue on a fishery containing 10 different aquatic plants to see how effective it is and to learn more about concentrations, water quality and how fast it dilutes. In time, these products could become really useful to fisheries looking to manage weed growth,” he added.

The news was welcomed by fishery managers who, without an effective weedkiller, often find themselves facing the expensive and labour intensive task of cutting weed and removing it by hand in order to satisfy customers struggling to fish heavily-weeded waters.

One fishery manager who has been successfully using Dyofix is Ed Turner, owner of Boldings Pools near Bridgnorth.

“I’ve been using Dyofix for three or four years now and I think it’s a fantastic product,” said Ed.

“I used to have serious algae problems in a few of my pools, but since I’ve used this stuff I haven’t had a single bloom.

“It even killed off much of the blanketweed and Canadian pondweed in my trout lake,” he added.

Distributor Peter Watson has confirmed with the Health and Safety Executive that his products don’t pose a risk to fish.

“Our products are fish-friendly weedkillers that work best when introduced in early spring followed by top-ups every two to four months. Treatment typically costs £16 to £20 per acre,” said Peter.
