MELBOURNE: Climate change will happen at an accelerated rate in Southeast Australia, with Tasmanian waters predicted to rise 2.5°C by 2050 and have large impacts for the fishing industry.

Tasmaia currently produces more than half of Australia’s seafood, and such an increase in water temperatures are predicted to affect rock lobsters (crayfish). The Tasmanian rock lobster fishery is the state’s second most important wild harvest fishery has an estimated value of $72 million.

“Fisheries and aquaculture really see themselves on the front line of change,” said marine researcher Alistair Hobday, from Australia’s national science agency, the CSIRO.
