Byfield National Park is a national park in the Shire of Livingstone, Queensland, Australia.
The members of the family Percichthyidae are known as the temperate perches. They belong to the order Perciformes, the perch-like fishes.
The Mary River cod is a species of temperate perch native to the coastal Mary River system of southern Queensland, Australia. Mary River cod are one of Australia's most endangered freshwater fishes and are notable for being the most northerly of the four Maccullochella cods found or once found in coastal river systems of eastern Australia.
The Bloomfield River cod or the tropical nightfish, is a species of temperate perch endemic to Australia. It is only found in an 11-km stretch of the Bloomfield River in northern Queensland. These waterfalls appear to have blocked the migration of more aggressive tropical freshwater fish species such as the sooty grunter that have presumably naturally displaced the Bloomfield River cod from its former range in prehistoric times. With its very limited distribution, the Bloomfield River cod is clearly a relict species. It is a very important relict species, however, as it is the most northerly distributed percichthyid species in Australia, and raises interesting questions on the biogeography of percichthyid fish in Australia and the history of their ancient colonisation of Australian rivers.
Anabas testudineus, the climbing perch, is a species of fish in the family Anabantidae, the climbing gouramis. It is native to Asia, where it occurs from India east to China and to the Wallace Line. It is an invasive species that can live without water for 6–10 hours. It is believed that the fish may be invading new territories by slipping aboard fishing boats. It has also been established in some countries outside of its native range, in eastern Indonesia and Papua New Guinea. It is believed to be advancing toward Australia. In late 2005, the fish was discovered on Saibai Island and another small Australian island in the Torres Strait north of Queensland, about three to four miles south of Papua New Guinea.
Agassiz's perchlet, also known as Agassiz's glass fish and the olive perchlet, is a species of ray-finned fish in the family Ambassidae. It is semi-transparent with dark scale edges forming a pattern over most of the body. It grows to a maximum of 7.5 cm. It is a macrophyte spawner with adhesive eggs. It is endemic to Australia. It was named for the zoologist Louis Agassiz.
Ambassis is a genus of fish in the family Ambassidae, the Asiatic glassfishes. They are found widely in the Indo-Pacific region, with species in fresh, brackish and coastal marine waters.
The yellow-fin perchlet is a species of fish in the family Ambassidae. It is endemic to Australia where it has only been recorded from the three rivers which drain into the Gulf of Carpentaria in northern Queensland. They are found in freshwater creeks and rivers with marginal vegetation, frequently recorded from freshwater streams that have quite high turbidity levels.
Ambassis fontoynonti, commonly known as the dusky glass perch, is a species of fish in the family Ambassidae. It is endemic to rivers in eastern Madagascar. Its natural habitat is rivers. It is threatened by habitat loss. The specific name honours the pathologist Maurice Fontoynont (1869-1948) who was president of the Malagasy Academy.
Cinetodus froggatti, known as Froggatt's catfish or smallmouthed salmon catfish, is a species of sea catfish found in West Papua in Indonesia and Papua New Guinea where it is found in the Purari, Fly, Strickland and Digul River systems as well as in the Roper River system of Northwest Territories, Australia.
Pingalla midgleyi is a species of fish in the family Terapontidae known by the common names black-blotch grunter and Midgley's grunter. It is endemic to the Northern Territory of Australia, where it occurs in the Alligator, Katherine, and Daly River systems. It is a resident of Kakadu National Park.
The honey blue-eye is an endangered species of fish in the subfamily Pseudomugilinae. It is endemic to southeastern Queensland, Australia, where it is found in mildly acidic, often tannin-stained, ponds and streams in wallum habitat.
The small-headed grunter is a species of fish in the family Terapontidae. It is endemic to Australia where it is known only from the upper Burdekin River in Queensland.
Puntius ambassis is a species of ray-finned fish in the genus Puntius from India.
Ambassis marianus, commonly known as the estuary perchlet, Ramsay's glassfish, estuary glassfish or glass perchlet, is a species of fish in the family Ambassidae. It is native to coastal eastern Australia. It gains its common name from its transparent appearance.
Ambassis nalua, the scalloped glassfish or scalloped perchlet, is a species of fish in the genus Ambassis. It is native to the Indo-Pacific region, form India to Australia and New Guinea, where it occurs in bays, estuaries and mangrove-lined creeks.
Ambassis jacksoniensis, commonly known as the Port Jackson glassfish or Port Jackson perchlet, is a species of fish in the family Ambassidae native to eastern Australia. It gains its common name from its transparent appearance.
Neosilurus hyrtlii, commonly known as Hyrtl's catfish or Glencoe tandan, is a species of catfish found across northern Australia, from the Pilbara to southeastern Queensland.
Scortum neili, Neil's grunter or the Angalarri grunter, is a species of freshwater ray-finned fish, a grunter from the family Terapontidae. It is endemic to the Northern Territory of Australia where it is restricted to the East Baines River and the Angalarri River, which are part of the Victoria River system. The adults are found in small, shady, streams with slow currents over substrates of mixed sand, silt and rock, as well as in deeper rocky pools in gorges. They prefer fresh and clear water at temperatures of 21 and 28 °C with the pH being neural or slightly basic. After spawning the male guard and fan the eggs. This is an uncommon species of grunter which frequently has one or two black blotches which can be placed randomly as well a number of indistinct pale vertical bars on the flanks, and a silvery stripe just beneath its eyes.
The lake grunter is a species of freshwater ray-finned fish, a grunter in the family Terapontidae. It is found in southern New Guinea and in northern Queensland in Australia. It prefers to live in still water, especially in heavily vegetated swamps, flood lagoons and small lakes.
