  • sexual reproduction in last copepodite stage; 11 moults: 5 naupliar stages, 6 copepodite stages (ref: Vijv1980)
  • cyclopoid: adult is carnivore, younger copepodites are omnivore, nauplii are herbivore (ref: Vijv1980)
  • dry weight: log10(W in mug) = 0.24 + 1.68 * log10(L in mm) (ref: VijvFran1976)


  • Acceleration starts at birth and continues till puberty, beyond metam; growth ceases at puberty
  • Data for females
