Discussion
- FEMALE total length at maturity - NOTE L50% is decreasing over time: we chose lowest L50% in North Sea datras dataset (2008)
- males are assumed to differ from females by {p_Am} and E_Hp only
Facts
- Preferred temperature 2 till 10 C (Ref: Wiki)
- Females are slightly larger than males and mature later, but differences are small (Ref: ICES)
- Pelagic till 7 cm, then demersal (Ref: ICES)
- Length-Weight relationship: W in g = 0.0157 * (L in cm)^2.8268 (Ref: ICES)
