Barramundi have a mild flavour and a white, flaky flesh, with varying amount of body fat.
This species has an elongated body form with a large, slightly oblique mouth and an upper jaw extending behind the eye. The lower edge of the preoperculum is serrated with a strong spine at its angle; the operculum has a small spine and a serrated flap above the origin of the lateral line. Its scales are ctenoid. In cross section, the fish is compressed and the dorsal head profile clearly concave. The single dorsal and ventral fins have spines and soft rays; the paired pectoral and pelvic fins have soft rays only; and the caudal fin has soft rays and is truncated and rounded.
Barramundi are salt and freshwater sportfish, targeted by many. They have large, silver scales, which may become darker or lighter, depending on their environments. Their bodies can reach up to 1.8 m (5.9 ft) long, though evidence of them being caught at this size is scarce. The maximum weight is about 60 kg (130 lb). The average length is about 0.6–1.2 m (2.0–3.9 ft).
Barramundi are demersal, inhabiting coastal waters, estuaries, lagoons, and rivers; they are found in clear to turbid water, usually within a temperature range of 26−30°C.
The barramundi feeds on crustaceans, molluscs, and smaller fish (including its own species); juveniles feed on zooplankton. The barramundi is euryhaline, but stenothermal. It inhabits rivers and descends to estuaries and tidal flats to spawn. In areas remote from fresh water, purely marine populations may become established.
The fish is of commercial importance; it is fished internationally and raised in aquaculture in Australia, China, Singapore, Saudi Arabia, Malaysia, India, Indonesia, Vietnam, Israel, Thailand, the United States, Poland, and the United Kingdom. A Singapore investment firm has invested in an upcoming barramundi fish farm in Brunei. The Australian barramundi industry is relatively established, with an annual production of more than 4000 tons. In the broader Southeast Asian region, production is estimated to exceed 30,000 tons.
Nile perch—a similar fish found in the Afrotropical realm, or sub-Saharan Africa—is often mislabeled as barramundi.
