| Water depth ranges from 30 to 70 m. Peak spawning activity occurs from October through December (Ref. 27353). In Northern Territory waters, spawning is more or less continuous over the year.
Spawning in lutjanids is sometimes timed to coincide with spring tides and it usually takes place at night (Ref. 28009, 5456), near open water (Ref. 28009). On the Great Barrier Reef however, 'redfish' (a common term for red sea perch) spawn throughout the full lunar cycle, over both spring and neap tides (Ref. 5456).
Sea perch in general are highly fecund, broadcast spawners (Ref. 28009). Fecundity increases with size increase in the females (Ref. 5456). Large females can produce at least 5-7 million eggs per season (Ref. 28009). |
