General description

CODEX is based on a discussion when SORTEX was presented to the fishery. Similarly to the concept of SORTEX, CODEX intends to separate cod and flatfish in the extension section of the trawl, whereas CODEX involves only one codend. Flatfish are being guided into the codend through a rather flexible entry in the lower part of the tunnel (a). By a panel (b), cod are guided towards the escapement opening in the upper part of the extension section.
