Trawlermen working in the Thames Estuary in the southern North Sea had suggested that square-mesh panels fitted to the underside of trawls used to catch Dover sole could reduce the catch and hence the discarding of unwanted benthos (e.g. urchins, crabs and starfish). A trawl was modified to incorporate a square-mesh section and was tested against a standard trawl on the MFV "Harvester". In September 2010, 34 hauls were conducted and the catches were sampled by Cefas scientists. Two experiments were conducted with the square-mesh panel in two different positions. A trawl fitted with a square-mesh panel near the footrope was the most successful design. It reduced the catch of unwanted benthos by 21% by volume, including 37% less volume of starfish, 27% less urchins and 23% less algae compared with a standard trawl. This design did not lose any marketable Dover sole, but caught significantly fewer Dover sole below the legal minimum landing size. MEDIN 3.1.1
