The species reaches a length of 5.9 ft or 1.8 m but this is scarce. The maximum weight of the fish reaches 130lb or 60 kg. The fish can grow to a size of around 2 pounds in a year, which makes it highly suitable for aquaculture.
Barramundi is also known as giant sea perch and giant perch. These are distributed through the coastal areas from the Persian Gulf to China. They are also found in the south of Papua New Guinea, southern Japan, and northern Australian. The fish species is found in Western Australia, north of Exmouth Gulf. These are abundant in Kimberley.
The Barramundi can live in freshwater or in saltwater. Their habitats are the rivers, streams, lakes, estuaries, billabongs, and coastal waters. They spend the maximum of their life in the rivers, migrating to the estuaries to breed. They then return back to the original river system. The barramundi is demersal and they are found in the turbid waters. The species will inhabit the rivers and descend to the estuaries to spawn.
When the monsoon season starts, the male Barramundi will migrate down the river to meet the females. The females lay a large number of eggs. Each female barracuda may lay several millions of eggs each. The adults do not protect the eggs and these require brackish water in order to develop.
The Barramundi will mostly feed on the molluscs, crustaceans and the small fishes. They may also feed on their own species. The juveniles feed on small fishes, zooplankton, aquatic fishes and prawns.
