World fish production is projected to reach 194 million tonnes in 2026, with an overall increase of 26 million tonnes, or 15 percent compared with the base period (average 2014-2026).

According to the OECD-FAO Agricultural Outlook 2017-2026, the main driver of this increase will be aquaculture, for which output is expected to be 34% higher in 2026 relative to the base period (average 2014-2026).

Global aquaculture production is anticipated to exceed the 100 million tonne mark for the first time in 2025 and to reach 102 million tonnes by 2026, as aquaculture is expected to be one of the fastest-growing food sectors despite its average annual growth rate slowing from 5.3% per annum in the previous decade to 2.3% in the period 2017-2026.

According to the outlook report, the bulk of aquaculture production will continue to come from Asian countries, which will account for about 90% of total production by 2026. China will remain the dominant producer, accounting for 63% of total aquaculture production by 2026.

By 2026, aquaculture will account for 53% of total fish production and 58% of total fish produced for direct human consumption (excluding non-food uses).

Of the 177 million tonnes of fish consumed worldwide in 2026, the lowest consumption is expected in Oceania and Latin America.
