Seaweeds and other aquatic plants production over time (1950–2024)
Follow seaweeds and other aquatic plants production for the world’s countries, year by year, from 1950 to 2024.
- The country ranked first changed over time: Japan in 1950–1963, China in 1964–2024. This is the first place among today’s countries: regions that later split, such as the former Soviet Union, have no values from before the split.
- Japan’s seaweeds and other aquatic plants production went from 145K t in 1950 to 315K t in 2024 (up 170K t).
- Japan ranked #1 of 24 countries in 1950 and #7 of 67 in 2024. The number of countries differs between the years, so the ranks are not directly comparable.

Notes on reading this history
Yearly values come from the same statistics of the Food and Agriculture Organization of the United Nations (FishStat). The number of countries with data differs by year, so each year’s ranks are given only among the countries that have data that year. Countries that produce none (zero) are not ranked. Weather and harvests make the yearly values go up and down. The “latest value” on the ranking page uses each country’s latest year, so it does not always match the ranks for a single year.
Seaweeds and other aquatic plants are counted as wet weight, as harvested, before they are dried. Most of them are farmed, not collected from the wild.
Regions that later split into several countries, such as the former Soviet Union, have a value for each new country only from the year it split. So older years have fewer countries with data, and values from before a split cannot be compared country by country with today’s countries. See the “Countries with data” row in the table.
