Lates calcarifer


The Lates calcarifer is a symbol of Western Australia’s Kimberley district, prized by recreational fishers for its size, taste and battling soul when snared. In Western Australia, there is a critical business fishery for barramundi and aquaculture tasks to deliver stock.

Barramundi lives in both saltwater and freshwater and rules numerous tropical streams. They eat nearly anything, including another barramundi, and can gulp prey up to 60 percent their very own length. Lates calcarifer can grow up to 200 cm long and 60 kg weight. During their lifecycle, they change sex from male to female for breeding.

Barramundi has a place with the ocean roost family. Furthermore, they have a particularly curved brow, pointed head, rounded tail fin, and extensive jaw. Although, they have a dorsal fin with seven or eight in number spines and a second dorsal fin of 10 or 11 straight lines.


Moreover, freshwater barramundi is a greenish-blue on the abdominal area and have tail fins that are dull darker to black. Saltwater Lates calcarifer have a brilliant greyish-silver body and yellow fins.

History of Lates calcarifer is given below:

Origin of Lates calcarifer

The Lates calcarifer is extensively spread in the Indo-West Pacific area from Southeast Asia. It also covers Northern Australia and Papua New Guinea.

Distinctive Features

Barramundi can be identified by a distinct pointed head, sunken forehead, substantial jaw reaching out behind the eye and a circular tail fin. They have a dorsal blade with eight in number spines and a second dorsal fin of eleven rays.

Geo-distribution of Barramundi

Universally, barramundi is known as Asian ocean bass, huge perch or monster ocean roost. They are dispersed all through seaside zones from the Persian Gulf to China and then to southern Japan. It covers south to Papua New Guinea and northern Australia regions also.

In Western Australia, they are discovered north from Exmouth Gulf, yet are most bounteous in the Kimberley.


Barramundi is big fish, with the greatest length of more than two meters, in spite of the fact that they are all more generally around 1.5 meters. Furthermore, Lates calcarifer can have a mass of more than 55 kilograms. As per the FAO species ID guide, they have a modestly profound, prolong, and compacted body.

Barramundi has pointed nose and big mouths, with jaws reaching out past the eyes. Nostrils are near one another. The dorsal fin is profoundly chiseled, with separated barbed and delicate dorsal blades.

Furthermore, the spikey dorsal fin has seven to nine spines. Similarly, the delicate dorsal fin has ten to eleven delicate rays. The butt-centric fin has three spines and seven to eight delicate rays on them. Pelvic and pectoral fins are also found in these fish.

Besides this, these fish have an unmistakable caudal peduncle, or you can say tail muscle, with a curved caudal fin. Moreover, the horizontal line expands onto the caudal fin.

big fish

Besides that, the scales of barramundi are immovably settled and ctenoid. Grown-up barramundi is silver with darker, blue-gray or olive backs. In cloudy (turbid) water, a shade is darker.

Adolescents are darker or once in a while they can be grayish-brown with three white stripes on the head and dispersed white spots somewhere else. Furthermore, the markings can be dim or may vanish voluntarily. Although the fins don’t have markings. The eyes are brilliant dark colored with a red reflective shine.

Average mass: 55 kg.

Other Physical Features: Heterothermic, Ectothermic, Bilateral symmetry

Average length: 1.5 m.

Sexual Dimorphism: Female larger


Ecology of barramundi is given below:


Barramundi can live in saltwater or freshwater. Besides this, habitats include rivers, streams, lakes, estuaries, billabongs and coastal waters.


Catadromous (fish which are born in salt water) Travelling from freshwater to the ocean to bring forth, e.g., European eels. Division of diadromous. Furthermore, migrations ought to be repeating, unsurprising and cover more than 100 km.

Food Habits

Adolescents eat little fish, oceanic creepy crawlies and little crustaceans, for example, prawns. Grown-ups eat fish, including another barramundi, and shellfish.

The behavior of Lates calcarifer

Catadromous barramundi populaces move seasonally among feeding and breeding grounds. Instantly after producing as tiny fish. Furthermore, Lates calcarifer larvae make their own way from the mouths of estuaries into freshwater or salty bogs or mangroves where they are shielded from predators.

Moreover, the developing fish tend to remain in the bogs from the months of February to April, before moving into lasting tidal rivers for an additional nine months. Besides this, after the nine months have passed, adolescent barramundi make their way into freshwater for further development.

Although, Barramundi come back to the mouths of the estuaries to breed. Lates calcarifer is discovered alone or in little groups. Moreover, they may school in feeding combinations when feeding on schools of little bait fish.

Other key Behaviors: Motile, Solitary, Social, territorial, Migratory, natatorial


The Lates calcarifer lifecycle combines estuarine, freshwater and marine stages. Besides this, in the wet season which is generally from October to April, they sexually develop grown-ups move from freshwater to seaside estuaries and waterway mouths for their spawning process.

Spawning normally happens after the full moon or new moon, when the tidal movement is most strong.

Furthermore, a huge female can produce up to 40 million eggs amid the spawning season. In spite of such high production, in excess of 90 percent of larvae and adolescents bite the dust in an initial couple of weeks or months.

Just 24 hours after fertilization, the Lates calcarifer is relatively prepared to bring forth from the egg. Moreover, after hatching, the larvae are not yet completely developed. The mouth and eyes are closed. Furthermore, the larva depends on a supply of nutrients from the yolk sac, which is as yet appended to it.

Wet season flows and high tides wash larvae and eggs into mangrove and tidal natural surroundings. At the second or third day of life, the mouth and eyes open and the larvae start scanning for food. Besides this, the first live food they eat is plankton which is microscopic animal organisms and plants that float in groups.

The larvae stay in the tidal territories or mangrove until the end of the wet season.

The young fish at that point move into freshwater billabongs and waterways, where they develop into grown-ups throughout three or four years. Moreover, if they do not approach freshwater they remain in seaside and estuarine regions.

At the point when the fish turn out to be sexually mature, normally at the age of three to five years, they move back to the saltwater for spawning and the lifecycle starts once again. Lates calcarifer are protandrous bisexuals, which means they change sex from male to female.

Furthermore, they turn out to be sexually developed as males at around three to four years old. Male fish turn into female fish from around five or six years old, and at that time they are around 80 cm long. Besides this, they require saltwater for changing their sex.


Barramundi ordinarily breeds in waterway mouths and water bays close zones of appropriate nursery environment. Besides this, their breeding season faround Darwin region coincides with the arrival to substantial spring tides and expanding water temperatures in mid to late August and endures until March.

Anyway, Lates calcarifer held under fake conditions can be produced throughout the entire year. Regions, for example, low-lying land and mangrove swamps that winds up overflowed during monsoonal rains and spring tides give perfect living spaces to youthful barramundi.

Furthermore, the female fish produces many million non-adhesive, pelagic, little, pink eggs between 0.6 mm to 0.9 mm in breadth. Although the eggs hatch in 15 to 20 hours at which time the hatchlings are around 1.5 mm long and the eyes and mouth are well created, despite the fact that the yolk sac is huge.

Besides this, at 2.5 mm the mouth is expansive and open. Although, the pectoral fins are starting to develop and the yolk sac is incredibly decreased. Over this size, the larvae start to show the trademark coloration of adolescents of this species.

They have in general darker mottled markings with a white stripe running longwise along the head of this species. Moreover, at 3.5 mm the yolk sac is all but left, the fin lines are starting to show up and the teeth are very much developed.

Besides this, by the fifth day, the yolk sac has been totally absorbed and by 8.5 mm the fins are completely grown.

Communication & Reception

Every single hard or bony fish have parallel lines which can be utilized to detect weight and to pass judgment on submerged streams and confined developments in the water.

Furthermore, the barramundi parallel line broadens onto the caudal blade. Although, Barramundi have reflective eyes which enable them to see better in dim or dark conditions.


Moreover, Lates calcarifer additionally have a feeling of smell. Methods of communication in barramundi are ineffectively comprehended.

Perception Channels: Tactile, Visual, Acoustic, Chemical vibrations


Maximum size: 2000 mm TL


Lates calcarifer can live to at least 20 years of their age.

Very less is known about the longevity of Lates calcarifer.
