Environment and Communications Reference Committee Inquiry into the impacts of climate change on marine fisheries and biodiversity
Australia’s fishing industry has greatly underperformed both in the catch of wild fish and in aquaculture. Australia could easily accommodate a tenfold expansion of aquaculture, currently worth $1 billion a year. It is prevented from doing so by the regulatory intrusions.
It is barely conceivable that human induced climate change, if it is taking place, could have an effect on fish numbers in the oceans – fish swim and plants also migrate in response to changing conditions. If there were to be any net effect of climate change it would be a shift in the locations of different species.
