Deadly box jellyfish and other tropical marine species could invade the Hunter’s coastal waters over the next 20 years due to climate change, a CSIRO marine ecologist has predicted. Marine life changes are also likely to have a major impact on commercial fishing and tourism.
Dr Alistair Hobday said CSIRO data showed water temperatures off the Australian east coast had already increased by two degrees over the past 20 years. A similar increase was likely to occur by 2030. As a result, a number of marine species including box jellyfish typically found in warmer Queensland would migrate south.
Warmer water fish species likely to move south include bigeye tuna, bronze whale sharks, striped marlin and sand flathead, Dr Hobday said. Newcastle Herald, 27 Aug 2007 – screencopy held by this website
