Whereas the interannual variability of the climate and fisheries of the Northern Hemisphere has been extensively documented 1 , very little is known about the interannual variability in the fisheries of the Southern Pacific Region. Recent work in the Northern Hemisphere has demonstrated the close relations between interan-nual variability in climate, the timing of events in the water column, the structure of food chains and recruitment to both marine and freshwater fisheries 2,3 . Forty years (1945-85) of observations at a coastal station (Maria Island, 42°36′S, 148°16′E) in Tasmania showed strong interannual variability in sea-surface temperatures. Maria Island is close to the region of convergence of the surface currents, on the equatorial side of the Subtropical Convergence (STC) water mass boundary 4 . The spring bloom was often extended by as much as three months in some years. Previous work 4 has not offered any explanation for the observed interannual variability and does not show any links with commercial fisheries. Here we explain the reason for the interannual climatic and oceanic vari-ability in Tasmania and show the links between climate and the fisheries. © 1988 Nature Publishing Group.
