Remarks | Inhabits coral reefs (Ref. 58534). Recorded as having been or being farmed in rice fields (Ref. 119549). Under hatchery conditions, larvae grow to juveniles in 26 days (Ref. 28133). The postlarvae (and possibly larvae) move from spawning areas to brackish water seasonal habitat (Ref. 28131). Larval barramundi occupy these habitats as well as main channels of streams (Ref. 6390). Juveniles live in freshwater lagoons, swamps and creeks (Ref. 28131). As these temporary habitats dry up, the juveniles move into the main stream and many migrate upstream to permanent freshwater habitats (Ref. 6390). 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). |
