ObjectivesThe Channel Ground Fish Survey (CGFS) is carried out every year on the French research vessel Gwen Drez (25 m, 600 HP) in October. The sampling area includes all the Eastern Channel and the southern North Sea (ICES divisions VIId and IVc4). This area is divided in rectangles of 15' of latitude and 15' of longitude and the sampling strategy type is systematic. The gear used is a bottom trawl GOV 19.70 / 25.90 m fitted with a double codend of 20 mm meshsize (stretched). The same hauls (2 in coastal waters or 1 offshore) are planned each year. Some additional hauls are done in high-density areas for juveniles of whiting. The haul duration has been fixed to 30 minutes and the fishing method is standardised (towing speed, warp length).
