Reproduction Preferences Additional Information
  • Age at maturity:In Ireland Pelvetia canaliculata is at least two years old before it reaches maturity (D. Stengel pers. comm.)
  • Pelvetia canaliculata produces gametes within receptacles on the tips of the fronds. Receptacles are initiated in January when they start to swell and become distinguishable. In July, the receptacles start ripening and gametes are released from August to early September, after which the receptacles are shed. Gametes are fertilised externally forming zygotes which then settle. A sporeling is produced of 800um length in six months. Plants first produce receptacles at a size of 4 to 5 cm long when they are in their first year.
