Reproduction Preferences Additional Information

Following an initial mating period in the spring, eggs are extruded during the late summer months and carried on pleopods. The eggs in P.borealis hatch the following March to May. Fecundity is closely linked to both temperature and female size. Reproductive maturity is reached in 18 months in hermaphrodites, and 3 months in primary females. Larvae is planktotrophic following an initial period of lecithotrophy (~6days), the larval duration is a function of temperature and sufficient food. In optimal North Sea conditions the larval period is 4 months. The frequency of breeding also depends on temperature and location, in the Barents Sea P.borealis breeds every other year, whilst P.danae breeds all year round. Generation time depends on which females are reproducing, a primary female will mature in 3 months, whilst the protandrous hemaphroditic females will become mature at 18 months.
