A fibre used in bullet-resistant armour and aeroplane cockpit doors may help reduce the number of salmon that escape from nets.

Retail fish supplier Loch Duart is hosting the first trials of 'Dyneema' nets in Sutherland, Scotland, to determine how successful the 'armour plated' nets are at fending off predator attacks and subsequent escapes.

Potentially saving fishermen thousands of pounds, Dyneema is said to be 15 times stronger than quality steel on a weight-for-weight basis. Standard fishing nets are made from nylon or similar materials.

The project will be followed by a trial by Marine Harvest Scotland, with results expected in 2010.

"High standards of containment are important to fish farmers for business reasons but also to wild fisheries to avoid problems associated with hybridisation with wild stocks," said Andrew Wallace, managing director of the Rivers & Fisheries Trusts of Scotland and Association of Salmon Fishery Boards.
