  • 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)


  • FEMALE total length at maturity - NOTE L50
  • males are assumed to differ from females by {p_Am} and E_Hp only
