increasing mesh size in the extension of a beam trawl
to improve the selectivity of sole
Target species:
sole
Area, Vessel
48 twin beam trawl tows were carried out in the North Sea (ICES IVc) on board the “Sonja” Z19
Gear type:
beam
Gear modification
The catches of a beam trawl with 100 mm diamond mesh netting in the extension are compared with the catches of beam trawl with a 150 mm diamond mesh extension.
Results:
The 150mm diamond mesh extension released more undersized sole. Commercial levels of catch of marketable sole were maintained.
