FLEXSELECT: a counter-herding device
to reduce bycatch in Norway lobster trawl fisheries
Target species:
Norway lobster (Nephrops norvegicus)
Area, Vessel
The trial took place in the Skagerrak (ICES IIIa) on board RV Havfisken (17 m, 373 kW)

Gear type:
demersal
Gear modification
The device, tested in a twin trawl rig against a control gear, consisted of four lines (mix wires and thick ropes) connected to a central metal ring, located approximately 20m ahead of the trawl mouth.

Results:
FLEXSELECT did not affect Norway lobster catch, while showing a significant reduction in bycatch of all fish species. The intensity of the effect varied among species and was strongly length-dependent for most roundfish species.
