Ecology Summary - Macquaria ambigua

Language:

Main Ref.	Kailola, P.J., M.J. Williams, P.C. Stewart, R.E. Reichelt, A. McNee and C. Grieve, 1993
Remarks	Golden perch have been recorded to travel up to 2000 km (Ref. 27443). They are also found in floodplain lakes of Western victoria and New South Wales, and stocked in dams and reservoirs (Ref. 6390). Migrations occur with floods and rises in river levels. Spawning probably needs to take place at least 500 km from the river mouth to ensure the pelagic juveniles are not carried into salt waters (Ref. 27443), so migrations may well be part of ensuring the success of spawning.
