| Description of life cycle and mating behavior |
A proportion of the population change sex from male to female after their first spawning season (Ref. 6390). Other fish remain functional males throughout their life and another small proportion develop directly into females at the age of 4 years (Ref. 27246, 28262). Also Ref. 28504.
The eggs and larvae are planktonic (Ref. 30572). After about four weeks the developed fry enter the estuary at night on the full moon and settle in estuarine littoral areas at about 1.4 cm in length (Ref. 30572). The fry rapidly develop into juveniles and grow to about 10 cm after one year (Ref. 30572).
