300mm diamond mesh mesh netting panels
to reduce discards of cod in a whitefish trawl in a trawl gear
Target species:
Haddock, whiting, cod, monkfish, megrim
Area, Vessel
30 twin trawl catch comparison hauls took place west of Shetland on board the Russa Taign K1102 (34 m, 2600 kW) during 2008.
Gear type:
twin trawl
Gear modification
A standard whitefish net that has 160 mm netting in the forward sections is compared to one with 300mm netting in the forward sections.
Results:
There were no losses of haddock or whiting. Fewer smaller cod (< 78 cm) were caught, but above 78 cm, there was no difference. Monkfish catches were 16% less, but these were all small (< 55cm). Megrim catches were reduced by 43%.
