Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

Oviparous. Eggs are laid in rocks or in kelp at depths of about 8 or 9 m and are present from March through September. Eggs are more abundant, however, in March and April. Eggs are hatched in about a year; size at hatching is about 18 cm. There may be a `nest' for several females laying eggs but this is not a true nest. A female lays two eggs at a time, for 6 to 12 spawnings.
