CONSUMERS will find it harder to buy salmon, king prawns and barramundi in coming years with a report showing climate change is threatening the nation's fish stocks.

Adelaide Now reports rising temperatures, ocean currents, rainfall and extreme weather will have negative impacts on the $2.1 billion fish industry and will also upset marine ecosystems, the Federal Government report to be released today warns.

Compiled by the Department of Climate Change, the report says the Tasmanian salmon, rock lobster and abalone industries, and barramundi, prawns and mudcrab fisheries in the north of Australia are most at risk.

The report did not specify any impact on South Australia's major fisheries, which has an export value of about $519 million.

It says coral reefs will also be affected, with coral bleaching likely to have flow-on effects for species such as the coral trout and red emperor.

Climate Change Minister Penny Wong said the report found climate change "is likely to affect not only the fishing industry itself, but also the regional and coastal communities the industry supports".
