The Barramundi (Lates calcarifer) is a species of fish that is native to Australia and New Guinea. It is commonly found from northern and eastern Australia through the Torres Strait to New Guinea. It is a salt and freshwater species. This species is also known as the Giant Perch, Giant Seaperch, Asian Seabass, Australian Seabass, White Seabass, and a variety of other names. Its nickname is the Silver Jack.
They have large silvery scales, which may become darker, depending on their environment. They can reach up to 70 inches in length, although smaller lengths are more common.
Barramundi feed on crustaceans, mollusks, smaller fish, and even will eat its own species. Young feed on zooplankton. It inhabits rivers and descends to estuaries and tidal flats to spawn. When the rainy season begins, males move downriver to meet females. Females lay millions of eggs which are not guarded. These eggs require brackish waters in order to develop properly. Most fish mature as males and become female after one or more spawning seasons. Most larger specimens are female.
These fish have a large commercial importance. They are fished internationally and raised in aquaculture in Australia, Malaysia, India, Indonesia, Thailand, the United Kingdom, the United States and the Netherlands. In the UK, the Aquabella Group can produce up to 8 tons of Barramundi per year for distribution throughout Northern Europe.
