100mm square mesh panels in the codend

to improve size selection and reduce undersized haddock in ICES Area VII

Target species:
Cod, haddock and other demersal species

Area, Vessel
11 hauls were carried out in the Celtic Sea on board MFV Crystal Sea during July and August 2014 using the twin rig method.
Gear type:
demersal (twin rig)

Gear modification
The standard gear was a coverless trawl and fished a 100mm codend. In addition, the modified gear had a (i) 100mm SMP in codend and a (ii) 100mm SMP @ 9 - 12m.


Results:
The modified gear released almost all small fish. There were losses of some marketable haddock, whiting, monkfish and plaice but these were mainly the smaller size classes.
