Macquarie perch are a medium sized freshwater fish native to the Murray-Darling Basin. They were historically found throughout the slopes and upland areas of the southern Murray Darling Basin and where a popular target for fishermen. However, populations began to crash by the mid 1900s because of river regulation, fish passage barriers, introduced species, sedimentation and pesticide use. By the 1970s, Macquarie perch were considered to be seriously threatened with extinction. Since then, the species has continued to decline, with populations considered viable as recently as 2005 having declined or disappeared.
