Barley may be the green answer for better sport; ANGLING: Two-year test planned to find ecological solution to algal bloom at Ravensthorpe Reservoir.

Byline: By Gareth Purnell

RAVENSTHOPE Reservoir is setting up a two-year field trial to evaluate the use of barley straw to help stop algal bloom problems, starting this month.

Ravensthorpe is the oldest English trout fishery, with around 100 acres of ecological diversity and is renowned for its excellent fishing.

Algal blooms in recent years have sometimes led to reduced catch rates during the peak periods.

"The barley straw application is an environmentally sustainable algal control method, which will benefit both the water treatment process and recreation activity," said a spokesman.

"The algal control activity of barley straw is described as preventing new growth of algae rather than killing already existing algae through a complex mechanism involving chemical, fungal and microbial factors."

This mechanism involves a series of very slow processes during which the straw is degraded and releases natural products that act on the algal growth.
