What is australian lungfish?
Australian lungfish to live in rivers and ponds with gentle flow and overgrown vegetation. In summer, the pond water is extremely devoid of oxygen, and other fish die in large numbers, but the barramundi can use lungs to breathe to survive. But it cannot live completely out of water, and in autumn the ponds are filled with fresh water, rich in oxygen, and they can breathe through their gills. Adult fish feed on mollusks, crustaceans, insect larvae, worms, etc. Barramundi are protected animals. Edible, meat taste quite good.
What does the australian lungfish look like?
It is about 125 cm long and weighs 10 kg. The body is long fusiform, covered with large and thin round scales. The pectoral and pelvic fins are leaf-shaped, and the fleshy part is scaly; the dorsal, caudal, and anal fins are connected into one. The swim bladder is very long and unpaired. There are two fibrous bands in the swim bladder. The back and the belly divide the swim bladder into left and right parts, and form many symmetrical septa on both sides, dividing the swim bladder into many symmetrical small air chambers (alveoli). Gills 5 pairs, well developed. Produced in Queensland, Australia. It can breathe with gills and swim bladders (lungs) simultaneously, or with lungs or gills alone. It likes to live in rivers and ponds with gentle flow and overgrown vegetation. In summer, the pond water is extremely devoid of oxygen, and other fish die in large numbers, but the barramundi can use lungs to breathe to survive. But it cannot live completely out of water, and in autumn the ponds are filled with fresh water, rich in oxygen, and they can breathe through their gills. The spawning period of barramundi is very long, generally from September to October as the peak period. Eggs are large, with a diameter of 6-7 mm, with a glial membrane and no stickiness. Eggs are laid among plants, and some sink to the bottom. Unlike other modern species of lungfish, barramundi juveniles have no external gills and no adhesive organs. Juveniles feed on filamentous algae, and adults feed on mollusks, crustaceans, insect larvae, and worms. Barramundi are protected animals. Edible, meat taste quite good.
australian lungfish living habits
In the rivers of Africa, America and Australia, there is a rare animal between fish and amphibians – lungfish. It appeared in the Devonian period 40,000 years ago. It is covered with tile-like scales, and its dorsal, anal and caudal fins are all connected together. fish. Scientists believe that lungfish were the first animals in nature to try to switch from water to land. The barramundi is the largest type of lungfish. The barramundi does not like to move very much. It often lies on the bottom of the water and does not move, but occasionally takes a breath on the surface of the water. Therefore, it is also called “lazy” fish.
australian lungfish rearing
- Due to the existence of lungs, barramundi does not have high requirements for dissolved oxygen in the water. Since they are highly sensitive to changes in the surrounding environment, the water changes should be minimized on the premise of ensuring the water quality is clear…
- In the juvenile stage of barramundi, it is suitable to feed some filamentous algae and other algae food, and in the adult stage, you can choose to feed mollusks, crustaceans, insect larvae, worms and other food.
