Using a 45mm square mesh codend
to reduce discards in a Nephrops trawl
Target species:
Nephrops
Area, Vessel
12 quad-rig catch comparison hauls took place at the Smalls ground in the Celtic Sea (ICES VIIg) on board MFV Stella Nova (DA57) (23.5m, 441kW).

Gear type:
demersal (quad rig)
Gear modification
A 45mm (nominal) square mesh codend was tested against a 75mm diamond mesh codend using identical quad-rigged Nephrops trawls. Nominal fishing circle was 420 X 80mm.

Results:
In the 45 mm square mesh codend there were small reductions in catches of unmarketable and tailed Nephrops and a small increase in catches of whole Nephrops.There were also small increases in haddock and whiting catches.
