using FRESWIND

to reduce the capture of flatfish and undersized roundfish in trawl fisheries

Target species:
Cod and other roundfish

Area, Vessel
Trials took place in the western Baltic sea (SD24) onboard the RV Clupea (28.80m, 478 kW) and the FV Crampas (18 m, 219 kW).
Gear type:
demersal

Gear modification
Fish entering the gear are guided sideways by the deflector towards the escapement window where size selection takes place. Fish not using FRESWIND to escape will be size selected in the codend.


Results:
(i) Using Freswind reduces catches of flatfish by between 54 and 66% and undersized cod by 32% (ii) There is a 7% loss of marketable cod.
