Effect of codend material type
on the selectivity of Baltic cod
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 made out of polyester was compared with a standard 120 mm T90 codend made out of polyethylene

Gear modification
A 120 mm T90 codend made out of polyester was compared with a standard 120 mm T90 codend made out of polyethylene
Results:
The codend constructed out of polyester caught significantly more cod under 44 cm. In particular, catches of undersized cod at the minimum conservation reference size of 35 cm were 5 times more likely to be caught in the polyster codend in comparison to the polyethylene one.
