Murray Cod Numbers Triple Where Felled Trees Are Put Back in the River

Researchers returned 4,450 pieces of timber to 110 km of Australia's Murray River; over seven years, Murray cod abundance tripled and golden perch density doubled in the restored reach

Researchers restored woody habitat along a 110-km section of Australia's Murray River by adding 4,450 timber structures. Over seven years, Murray cod numbers tripled and golden perch numbers doubled in the restored reach, with fish movement from connected source populations also contributing to the increase.

Murray Cod Numbers Triple Where Felled Trees Are Put Back in the River

Australia spent decades pulling timber out of its longest river to move irrigation water faster, before it began putting wood back, with 4,450 snags from highway clearing placed along a 110-kilometre stretch of the Murray. That is according to Dr Jarod Lyon of Victoria’s Arthur Rylah Institute for Environmental Research, whose research, published in Ecological […]

Researchers returned 4,450 pieces of timber to 110 km of Australia's Murray River; over seven years, Murray cod abundance tripled and golden perch density doubled in the restored reach - THE LOCAL REPORT ARTICLES

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 ...
