The name ‘Barramundi’ is a loanword from an Australian Aborginal language of the Rockhampton area in Queensland.

The Barramundi fish are opportunistic predators. They generally eat microcrustaceans such as copepods and amphipods as juvenile fish under 40 mm.

The larger juveniles eat macrocrustaceans such as Penaeidae and Palaemonidae. They start eating macrocrustaceans after reaching 80 mm, and also pelagic bony fishes.

The larger fish generally eat around 80 percent bony fish. They generally swallow their food whole, sucking their prey into their fairly large mouths.

In commercial production, the Barramundi fish are now fed on compounded pellets. But trash fish is still used in the areas where it is cheaper or more available than pelleted diet.


The male Barramundi fish migrate downriver to meet females at the start of the monsoon. The females generally lay very large numbers of eggs, which can reach several millions.

The adults do not guard the eggs or the fry. The eggs need brackish water to hatch, the the fry to develop.


The Barramundi is very popular as food fish. It is economically very important and has great popularity throughout the world.
