Description of life cycle and mating behavior | Mature adults form large schools in preferred spawning areas (Ref. 6390). They are serial spawners (Ref. 6390). Spawning generally occurs in waters less than 50 m deep (Ref. 6390). They generally only spawn when water temp is equal to 18°C (Ref. 6390). There have been no investigations of sex reversals in Australian snapper populations. However, in New Zealand, some juvenile snapper change sex from female to male but all such changes are completed by the onset of maturity (Ref. 28040). |
