Trout given assistance to spawn in the River Welland

Fish in a Cambridgeshire river have been given a helping hand to spawn.

Sea trout have found it difficult to breed in the River Welland, near Peterborough, and in 2000 there were no wild fish found there during surveys.

The Environment Agency has spent £25,000 from Defra on creating gravel riffles, which are shallow stretches of water with a faster current.

The agency is hoping the riffles will encourage insect life and aid the fish during periods of low water flow.

Sea trout spawn in fresh water and then migrate to spend most of their lives in the sea.

Chris Randall, of the Environment Agency's fisheries, recreation and biodiversity team, said: "The River Welland used to contain a thriving population of sea trout but the fish seem to have all but disappeared over the last 30 years.

"The habitat enhancement works on the river will provide spawning areas, shelter for the fish during various stages of their lives and help to increase insect life to provide a food source."
