| Definition | This is the standard net used by the CEFAS fisheries laboratory for beam trawl surveys in UK coastal waters. The net is held open by a 4m (measured inside the end plates) metal beam with a chain mat attached to the beam to increase seabed disturbance. 75mm cod ends were optionally fitted with 40mm liners. Post-1991 80mm (post-1991) cod ends were always fitted with 40mm liners. | |
