"Southern Australia’s sharks and rays face mounting threats as warmer waters push more tropical species southwards and habitats change, exacerbating threats to critically endangered species.
A study aimed at identifying the risks to some 132 different species found in waters ranging from south-west Western Australia to NSW has been published in the Fish and Fisheries journal. It seeks to give authorities a method to prepare for the threats of overfishing and climate change.
“This is the first time we’re actually bringing them together as a risk assessment,” said Terence Walker, a research fellow at both Melbourne and Monash universities and lead author of the paper. “The challenges for fisheries managers are growing all the time.”"
