increasing codend mesh size and inserting a square mesh panel

to reduce discards of haddock and whiting in a seine net

Target species:
Haddock, whiting and cod

Area, Vessel
90 alternate shots were carried out west of Shetland on board the Harmony LK63 (23m, 298hp) during 2001.
Gear type:
Scottish seine

Gear modification
A seine net fishing a 100 mm diamond mesh codend was compared with one fishing (i) a 110 mm mesh codend; (ii) a 110 mm mesh codend with a 90 mm smp 6 – 9m from the codline; and (iii) a 120 mm cod end.


Results:
There was a substantial reduction in the discarding of undersized haddock and whiting in all three codends. Fitting a 90mm square-mesh panel in the 110mm cod-end substantially reduced catches of both undersized and marketable fish.
