CSIRO’s Climate Adaptation and Wealth from Oceans Flagships has identified 45 species, representing about 30 per cent of the inshore fish families occurring in the region, that exhibited shifts thought to be climate-related.
These include warm temperate surf-zone species such as Silver Drummer and Rock Blackfish that are breeding and have become more abundant, and range increases in Snapper and Rock Flathead. There is also a greater abundance of warm water tunas and billfishes and occasional visits from Queensland Groper and Tiger Sharks.
In this podcast Curator of the Australian National Fish Collection, CSIRO’s Dr Peter Last, explains the shift in the distribution of marine animals in response to climate change over the past 70 years.
