200mm diamond-mesh netting in the wings, square and back sections of a trawl
to improve size selection and reduce undersized haddock in ICES Area VII
Target species:
Cod, haddock and other demersal species
Area, Vessel
18 hauls with a single-rig; 9 tows with each rig, on board MFV Valhalla in the Celtic Sea. August and September 2014.
