Golden perch (Macquaria ambigua)Restoring woody habitat in a degraded section of Australia's Murray River has led to a major increase in the populations of two native fish species.
In the research carried out over seven years, the number of Murray cod in the restored reach increased threefold, while the population of golden perch increased twofold.
The aim of the study was to examine whether adding large pieces of coarse woody habitat could increase fish populations.
