Ecology Summary - Anguilla australis

Language:

Main Ref.	Kailola, P.J., M.J. Williams, P.C. Stewart, R.E. Reichelt, A. McNee and C. Grieve, 1993
Remarks	Diadromous. They move from marine to fresh waters as juveniles and return to the sea as adults. These eels live in a variety of freshwater and estuarine environments including coastal lagoons, rivers, creeks, swamps, lakes and farm dams (Ref. 26507). Shortfin eels are found in slow flowing streams or still waters (Ref. 26509). Glass eels move into estuaries between late autumn and spring. Mainly nocturnal feeders with a well developed sense of smell for locating prey. Diet includes crustaceans, molluscs, aquatic and terrestial insects (Ref. 26514), and bony fish (including elvers) (Refs. 26513, 26514).
