1998

Lange, Klaus | Tönjes, Mentjes

An EU funded research project was started in 1998 by institutes from Ireland, Belgium, the Netherlands and Germany to reduce the adverse environmental impact of demersal trawls. In the frame of this project the Institute for Fishery Technique of the Federal Research Centre for Fisheries, Hamburg, is developing a jet beamtrawl replacing the heavy tickler chains of a traditional flatfish beam trawl by water jet nozzles placed at the lower side of the beam with the jets directed towards the sea bottom. First trials on the dutch research vessel “Tridens” were performed in March 1998. Catch and bycatch of a jet beamtrawl and a traditional beamtrawl were compared. Theefficiency of the jet beamtrawl was not satisfactory and will have to be improved.
