Global production scale
FAO reported 223.2 million tonnes of combined fisheries and aquaculture production in 2022. Aquatic animal production made up 185.4 million tonnes, while algae production reached 37.8 million tonnes. Aquaculture’s total production reached 130.9 million tonnes, making it a central part of the overall aquatic-food system rather than a small supplemental source.
The 94.4 million tonnes of farmed aquatic animals in 2022 represented a majority share of the 185.4 million tonnes produced globally. That 51% share is a useful dividing line: by 2022, farmed aquatic animals had moved ahead of capture fisheries in the global production mix. The same FAO source estimated global annual per-capita consumption of aquatic foods at 20.7 kilograms in 2022.
The production figures describe physical output, while value measures describe a different dimension of the sector. FAO estimated the total first-sale value of aquaculture production at USD 313 billion in 2022. “First-sale value” refers to the value at the initial sale point, so it should not be read as the retail value of seafood served by restaurants or sold through later supply-chain stages.
Global apparent consumption of aquatic animal foods reached 162.5 million tonnes in 2021. This is a consumption measure from a different year than the 2022 production figures, so the two numbers should not be treated as a direct same-year balance.
Where aquaculture is produced
Aquaculture production is geographically concentrated. Asia produced 70% of global aquatic animals in 2022. Europe and Latin America and the Caribbean each produced 9%, Africa produced 7%, Northern America produced 3%, and Oceania produced 1%, according to FAO’s 2022 figures.
The country-level distribution is even more concentrated. China produced 36% of global aquatic animals in 2022. India accounted for 8%, Indonesia for 7%, Viet Nam for 5%, and Peru for 3%. Across the sector, the 10 leading aquaculture-producing countries accounted for more than 89.8% of total aquaculture production in 2022.
| Geography | Share or output | Measurement period |
|---|---|---|
| Asia | 70% of global aquatic animals | 2022 |
| Europe | 9% of global aquatic animals | 2022 |
| Latin America and the Caribbean | 9% of global aquatic animals | 2022 |
| Africa | 7% of global aquatic animals | 2022 |
| China | 36% of global aquatic animals | 2022 |
| India | 8% of global aquatic animals | 2022 |
| Indonesia | 7% of global aquatic animals | 2022 |
| Viet Nam | 5% of global aquatic animals | 2022 |
These percentages use global aquatic animal production as the reference, not necessarily the same denominator as regional value or species-specific statistics. For a coastal-food reader, the main implication is that global aquaculture trends are strongly shaped by Asian production, while regional specialties may reflect very different species and farming systems.
Long-run growth and value
The FAO’s The State of World Fisheries and Aquaculture 2022 recorded total aquaculture production of 122.6 million tonnes in live weight in 2020. The estimated total farm-gate value was USD 281.5 billion. Farm-gate value is measured at the point where the product leaves the farm, so it is distinct from first-sale value and from consumer prices.
The 2020 total was 6.7 million tonnes higher than the 2018 total. Over the much longer period from 1990 to 2020, world aquaculture output expanded by 609%, with average annual growth of 6.7%. These are long-run historical measures; they do not constitute a forecast of future growth.
The 2020 production mix included 57.5 million tonnes of farmed finfish, 17.7 million tonnes of farmed molluscs, and 11.2 million tonnes of farmed crustaceans. The different groups have different production methods, market destinations, and value profiles, so a single sector-wide total can hide substantial variation.
The 2020 estimated values illustrate that variation. Farmed finfish had a reported value of USD 109.8 billion for inland production and USD 36.2 billion for mariculture and coastal farmed finfish. Farmed molluscs had an estimated value of USD 29.8 billion, while farmed crustaceans had an estimated value of USD 81.5 billion. All of these values refer to 2020 estimates from the FAO aquaculture production chapter.
Inland, marine, and coastal systems
Inland aquaculture reached 54.4 million tonnes in 2020. It represented 44.4% of total aquaculture production of animal species and algae. When the denominator is limited to aquatic animals, inland farming represented 62.2% of total aquaculture production in that year.
Marine and coastal aquaculture together produced 68.1 million tonnes in 2020. That total included 33.1 million tonnes of aquatic animals and 35.0 million tonnes of algae. The algae component is important: marine and coastal systems are not synonymous with finfish or shellfish farming.
Coastal aquaculture supplied 3.1 million tonnes of finfish in 2020. Coastal aquaculture represented 37.4% of the combined 8.3 million tonnes of mariculture and coastal finfish production. The comparison concerns finfish within those specific marine and coastal categories, not all aquaculture output.
| Production setting or group | Quantity or share | Year |
|---|---|---|
| Inland aquaculture | 54.4 million tonnes | 2020 |
| Marine and coastal aquaculture | 68.1 million tonnes | 2020 |
| Marine and coastal aquatic animals | 33.1 million tonnes | 2020 |
| Marine and coastal algae | 35.0 million tonnes | 2020 |
| Coastal farmed finfish | 3.1 million tonnes | 2020 |
| Non-fed aquaculture | 27.8% of farmed aquatic animal production | 2020 |
| Non-fed animal-species aquaculture | 24.3 million tonnes | 2020 |
Non-fed aquaculture accounted for 27.8% of total farmed aquatic animal production in 2020, and non-fed animal-species aquaculture produced 24.3 million tonnes. The category includes production whose feed profile differs from fed-fish systems, so it offers a useful lens for distinguishing production models within the wider aquaculture total.
Leading farmed species and groups
Inland aquaculture produced 49.1 million tonnes of finfish in 2020. The estimated value of inland farmed finfish was USD 109.8 billion. By comparison, mariculture and coastal aquaculture produced 8.3 million tonnes of finfish, with an estimated value of USD 36.2 billion.
Species concentration is visible within these totals. Grass carp production reached 5.8 million tonnes in 2020 and represented 11.8% of global inland aquaculture. Grass carp plus 23 other individual species contributed 78.7% of inland-farmed finfish production. This measure covers inland-farmed finfish, not every farmed aquatic animal or all algae.
Atlantic salmon production reached 2.7 million tonnes in 2020 and represented 32.6% of marine and coastal farmed finfish. Air-breathing fish production reached 6.2 million tonnes and represented 12.6% of inland-farmed finfish. These figures show why species-level comparisons need a clearly stated denominator: salmon’s percentage is based on marine and coastal farmed finfish, while the air-breathing fish percentage is based on inland-farmed finfish.
For coastal cooking, the species distinction is practical as well as statistical. Finfish, molluscs, and crustaceans are counted separately in the FAO benchmarks, and the production setting can differ sharply between inland ponds, marine farms, and coastal operations. Production volume alone does not identify the species, the farming environment, or the point in the supply chain at which value is measured.
European and U.S. benchmarks
Eurostat reported that EU aquaculture produced about 1.0 million tonnes of aquatic organisms in 2024, valued at €4.6 billion. Norway, reported in the same Eurostat source for comparison, produced 1.6 million tonnes valued at €9.5 billion in 2024. These are 2024 figures and use euros, so they should not be compared with the FAO’s 2020 dollar values as though they were a single harmonized valuation series. The source is Eurostat’s Aquaculture statistics.
Within the EU, aquaculture accounted for 91.4% of Malta’s total fisheries production by live weight in 2023 and 69.8% of Greece’s total fisheries production by live weight. Rainbow trout represented 17.9% of all EU aquaculture production by value in 2023. Ireland produced about 13,400 tonnes of farmed salmon in 2024.
The United States provides a separate benchmark. NOAA estimated freshwater and marine aquaculture production at 688 million pounds in 2023, with an estimated value of USD 1.6 billion. These estimates are reported in pounds and U.S. dollars, while the global and European figures above are primarily reported in tonnes and, in some cases, euros. The NOAA figures are available from Aquaculture | NOAA Fisheries.
For interpreting local seafood markets, the measurement unit and scope matter. EU figures cover aquatic organisms, the U.S. figures combine freshwater and marine production, and the global FAO figures distinguish aquatic animals, algae, species groups, and production environments. Keeping those definitions visible helps connect broad aquaculture statistics with the coastal ingredients that eventually reach a bistro kitchen.
