going south for the winter

Tropical fish lured south by currents.

The leader of the CSIRO’s Marine Climate Impacts and Adaptation Stream, Alistair Hobday, used modelling to indicate the likely future occurrences of 14 fish species throughout each month of the year.

In 95 per cent of the 25 scenarios, most species moved south, pointing to a pole-ward shift. Predictions are for more pelagic fish in southerly latitudes.

The evidence is backed by sightings of blue and striped marlin off Tasmania and Gippsland, and marlin, cobia, wahoo and Spanish mackerel in southern NSW.
