CSIRO scientists studying the ear bones of coastal and long-lived deep-ocean fish species in the south west Pacific have discovered the growth of the fish has been affected by climate change. 

Dr Ron Thresher and his team from CSIRO’s Wealth from Oceans Flagship examined 555 specimens ranging in age from two to 128 years, with birth years from 1861 to 1993.

Their findings have been published in the US science journal, Proceedings of the National Academy of Sciences

In this five and a half minute podcast Dr Thresher explains how the warming of the oceans is affecting fish.
