| Spawning Cycles: | (1/y) | Ref: | |||||||||||
| Comments: | Mature Westralian jewfish migrate to shallower waters during the spawning season. They aggregate around inshore reefs in about 20 m of waters, although actual spawning appears to take place on isolated outcrops of reef or flat, weed-covered sandy substrates away from a main reef (Ref. 6390). Spawning peaks in January and February when water temperatures are high and plankton is abundant (Ref. 27560). Fecundity increases with size and up to 4 million eggs were estimated in fish of 81 to 87 cm. Potential fecundity was up to 6.8 million (Ref. 27621). | ||||||||||||
