Discard sampling of plaice (Pleuronectes platessa) and cod (Gadus morhua) in the North Sea by the Dutch demersal fleet from 2004 to 2006

Research output: Book/ReportReportProfessional

Abstract

Since 2002, Wageningen IMARES samples discards of the Dutch demersal (beamtrawl) fishery following the EC Data Collection Regulations (DCR) 1543/2000 and 1639/2001. In response to concerns about quality issues of these discard data, the Dutch Fish Product Board together with the Dutch fishing industry started its own plaice discards program in 2004. Samples of plaice and cod discards and landings are taken by fishermen on about 20 demersal vessels. Previous analysis of the Product Board’s dataset provided evidence for clear trends in time, spatial patterns, and differences between gears and individual vessels. Furthermore, it was pointed out that the IMARES program estimates higher discard percentages for plaice than the self-sampling program.
