Discussion
- males are assumed not to differ from females
Facts
- Preferred temperature 6 C (Ref: fishbase)
- Females are slightly larger than males and mature later, but differences are small (Ref: ICES)
- Semi-pelagic species that is not bound to a demersal life style (Ref: ICES)
- Length-Weight relationship: W in g = 0.00708*(TL in cm)^3.08 (Ref: fishbase)
