The CSIRO have developed a DNA test capable of improving management of wild fish populations by determining the ages of fishes.
The cost effective and non-lethal alternative to counting growth rings can be used for conservation or harvesting, proving a vital tool towards the management of fisheries.
Postdoctoral member of the CSIRO Doctor Ben Mayne said, "We’re now hoping to share this test with fisheries managers to support conservation projects and sustainable fisheries worldwide.”
