using a T90 netting codend

to improve the selectivity of whiting and pouting in the beam trawl fishery

Target species:
sole

Area, Vessel
15 beam trawl tows were carried out in the Southern North Sea (ICES IVc) on board the RV Belgica.

Gear type:
beam

Gear modification
The catches of a standard 80 mm diamond mesh codend (T0) are compared with the catches of an 80mm T90 codend where the standard orientation of the netting is rotated by 90 degrees.

Results:
The T90 codend releases more whiting and pouting than the standard codend. There may be a higher retention of flatfish (dab, plaice and sole).
