Effect of increasing circumference of T90 codends

on Baltic cod selectivity

Target species:
Cod (Gadus morhua)

Area, Vessel
The trial took place in the Baltic Sea (ICES 24 and 25) on board R218 Judith Bechmann (26 m, 485 kW)
Gear type:
demersal

Gear modification
A 120 mm T90 codend with a circumference of 92 meshes was compared with a standard T90 120 mm codend with a circumference of 50 meshes


Results:
The codend with a larger circumference caught significantly more cod under 47 cm, and in particular it caught significantly more under sized cod less than the minimum conservation reference size (MCRS) of 35 cm.
