Abstract

Net primary productivity varies greatly around Australia, with highest rates in coastal zones and in seas between Australia and its northern neighbours. Although there is a strong seasonal trend, increasing during spring-summer and decreasing in autumn-winter, average net primary productivity has declined in Australian waters by 12 % in the past 17 years (2002-2019). Given that primary production sets the carrying capacity of higher trophic levels (zooplankton, fish, birds and mammals), this decrease is likely to cause a reduction in the size of Australia’s fisheries.
