A New Freshwater Catfish (Pisces: Ariidae) from Northern Australia
Rec. West. Aust. Mus. 1988,14(1): 73-89 A new freshwater catfish (Pisces: Ariidae) from northern Australia PatriciaJ. Kailola* and Bryan E. Pierce* Abstract A new species of fork-tailed catfish is described on the basis of 31 specimens collected in northern Australia between the Fitzroy River (Western Australia) and the Mitchell River (Queensland). Arius midgleyi sp. novo grows to at least 1.3 m TL and is distinguished from other Australo-Papuan ariids by a combination of charac ters including snout shape, barbel length, eye size, tooth arrangement and gill raker number and position. Comparison is made with other ariid species occurring in northern Australian rivers, including the morphologically similar A. leptaspis (Bleeker). Introduction The Timor Sea and Gulf of Carpentaria drainage systems (Lake 1971) approx imately represent the Leichhardtian zoogeographic region of Whitley (1947). The rainfall pattern in this region is dominated by the wet monsoon (occurring within the period November to April). Most rivers here traverse a flat coastal plain about 15 km wide before reaching the sea (Lake 1971). These rivers commonly possess wide flood plains and low gradients, often contracting to a chain of waterholes during the dry season; some (Gregory River; Fitzroy to Daly Rivers) have reaches of rapids or very deep gorges. The average annual discharge from this region is 69000 billion litres (Lake 1971), most of it occurring during the wet season. Five of Australia's 18 species of fork-tailed catfishes (Ariidae) are common in this northern region, yet were overlooked by Whitley (1947) and Iredale and Whitley (1938). The members of this family, which is distributed circumglobally in the tropics and subtropics, may inhabit the sea, rivers within tidal influence, or fresh waters. -
Estuarine Wetlands
ESTUARINE WETLANDS • An estuary occurs where a river meets the sea. • Wetlands connected with this environment are known as estuarine wetlands. • The water has a mix of the saltwater tides coming in from the ocean and the freshwater from the river. • They include tidal marshes, salt marshes, mangrove swamps, river deltas and mudflats. • They are very important for birds, fish, crabs, mammals, insects. • They provide important nursery grounds, breeding habitat and a productive food supply. • They provide nursery habitat for many species of fish that are critical to Australia’s commercial and recreational fishing industries. • They provide summer habitat for migratory wading birds as they travel between the northern and southern hemispheres. Estuarine wetlands in Australia Did you know? Kakadu National Park, Northern Territory: Jabiru build large, two-metre wide • Kakadu has four large river systems, the platform nests high in trees. The East, West and South Alligator rivers nests are made up of sticks, branches and the Wildman river.
