Found in coastal waters, estuaries and lagoons, in clear to turbid water (Ref. 5259, 44894). A diadromous fish, inhabiting rivers before returning to the estuaries to spawn. A protandrous hermaphrodite (Ref. 32209). Larvae and young juveniles live in brackish temporary swamps associated with estuaries, and older juveniles inhabit the upper reaches of rivers (Ref. 6390, 44894). Have preference for cover on undercut banks, submerged logs and overhanging vegetation (Ref. 44894). Feed on fishes and crustaceans. They reach 1500-3000 g in one year in ponds under optimum conditions (Ref. 11046, 44894). Juveniles also eat insects (Ref. 44894). Sold fresh and frozen; consumed steamed, pan-fried, broiled and baked (Ref. 9987). A very popular and sought-after fish of very considerable economic importance (Ref. 9799). Presently used for aquaculture in Thailand, Indonesia and Australia (Ref. 9799). Australia's most important commercial fish and one of the most popular angling species (Ref. 44894).
Breed in estuaries throughout the Indo-Pacific. Maturing male barramundi migrate downstream from freshwater habitats at the start of the wet (monsoon) season to spawn with resident females in estuaries (Ref. 27132) and on tidal flats outside the mouths of rivers (Ref. 6390).
Barramundi spawn on the full moon and new moon, primarily at the beginning of an incoming tide which carries the eggs into the estuary (Ref. 28135).
Barramundi are broadcast spawners that aggregate to spawn (Ref. 6390). Spawning aggregations occur in or around the mouths of rivers (Ref. 28132). While adults and juveniles are capable of living in fresh water, brackish waters are required for embryonic development (Ref. 6136). Female barramundi are capable of producing large numbers of eggs, with estimates as high as 2.3 million eggs per kg of body weight (Ref. 28134).
Barramundi are protandrous hermaphrodites, i.e., they undergo sex reversion during their life cycle. Females are generally absent in the smaller length classes, but dominate larger length classes. Most barramundi mature first as males and function as males for one or more spawning seasons before undergoing sex inversion. A few females will develop directly from immature fish (Ref. 28132). Similarly, some males may never undergo sex inversion (Ref. 28132). Also Ref. 103751.
