An environmental flow through the Murray River has encouraged the migration to the Goulburn Valley of a number of fish species in short supply.
The co-ordination of environmental flows to the Goulburn and Campaspe rivers has been used to distribute golden perch, silver perch and other native fish in an effort to encourage fish movement and increase populations throughout the basin.
DELWP’s Arthur Rylah Institute’s principal research scientist Jarrod Lyon said researchers monitored tagged fish and found species used the flows to move into the tributaries.
‘‘These results show that migration of native fish could be a substantial driver of populations,’’ Mr Lyons said.
‘‘Using this information, our environmental watering programs can use these flows as a targeted management action to assist the recovery of native fish populations in the tributaries of the Murray.
‘‘By co-ordinating the delivery of environmental flows in northern Victoria we are making sure we maximise the shared benefits of water for productive, environmental, cultural and recreational users.’’
The development and implementation of environmental watering programs in Victoria occurs as a collaborative process between Victorian and Commonwealth government agencies, land managers and water authorities.
