There is no single FAO-designated “most farmed fish” species in the global ranking. By production weight, FAO’s largest 2023 aquaculture group was Carps, barbels and other cyprinids, at 33.2 million tonnes. That group contains 46 species items, so it should not be described as one carp species. Separately, this live counter visualizes an approved estimate of 100 billion individual farmed fish each year; it is a Fishcount-style count of fishes killed for food, not a tonne measure of all aquaculture.

In Depth
What is the most farmed fish in the world?
There is no single FAO-designated species answer in the global production ranking. By production weight, FAO’s largest aquaculture group in 2023 was “Carps, barbels and other cyprinids,” with 33,226,179 tonnes. It is a freshwater-fish group containing 46 ASFIS species items, not one carp species. A production-weight ranking cannot establish which species represents the most individual fish.
The 100 billion annual counter is an approved rounded estimate of individual farmed fishes killed for food. It is not a FAO live-stock count or a tonne measure of all aquaculture. Fishcount’s 2019 estimate was 124 billion farmed fishes, with a published range of 78–171 billion; the page’s 100 billion visualization remains within that uncertainty range and all of its live rates derive from the same approved total.
Yes, for aquatic-animal production. FAO reports that aquaculture produced 94.4 million tonnes of aquatic animals in 2022, or 51% of global aquatic-animal production, surpassing capture fisheries for the first time. This comparison excludes algae but is broader than finfish alone.
The 100 billion counter is an estimate of individual farmed fishes killed for food; it is not an FAO-reported count of all aquaculture organisms.
FAO’s leading 2023 aquaculture production category, Carps, barbels and other cyprinids, is a 46-item freshwater-fish group rather than a single carp species.
FAO’s 2023 global aquaculture production total of 136.2 million tonnes includes aquatic plants as well as aquatic animals, so it should not be described simply as farmed-fish tonnage.
In 2022, aquaculture supplied 51% of global aquatic-animal production, surpassing capture fisheries for the first time in that measure.
Production rankings by tonnes cannot tell us which species accounts for the greatest number of individual fish, because average body sizes differ substantially.
Aquaculture is broader than finfish farming: official global output tables also include crustaceans, molluscs, aquatic plants, and other groups.
Frequently Asked Questions
What is the most farmed fish in the world?
FAO’s global ranking does not identify one single most farmed species. By production weight in 2023, its largest group was “Carps, barbels and other cyprinids” at 33,226,179 tonnes. This is a 46-item freshwater-fish group, not one carp species.
What does the Farmed Fish counter count?
It visualizes an approved estimate of 100 billion individual farmed fishes killed for food each year. It is not a FAO-reported count of every aquaculture organism and it is not a tonnes measure of production.
Does the most farmed-fish ranking measure individual animals?
No. FAO’s species-group ranking is by production weight in tonnes. It cannot show which species accounts for the most individual fish, because farmed fish differ greatly in average size.
Has aquaculture become larger than capture fisheries?
For aquatic-animal production, yes. FAO reports that aquaculture supplied 51% of global aquatic-animal production in 2022, the first time it surpassed capture fisheries in that measure. This is broader than finfish alone and excludes algae.
HumanConsumption.Live converts this authoritative annual estimate into a continuously updating rate across the current calendar year. The counter visualizes that pace; it is not a direct real-time measurement from the source organization.
Fishcount estimates 124 billion farmed fishes killed for food in 2019, with a 78–171 billion range. The page retains its approved rounded 100 billion annual visualization, which sits within that range. The live counter is calculated from that approved total; it is not a real-time source feed.
FAO’s 136.2 million-tonne global aquaculture table is a production-weight ranking across all groups, including aquatic plants, crustaceans and molluscs as well as fishes. The 33.2 million-tonne leading group is “Carps, barbels and other cyprinids”; it should not be treated as a single species or compared directly with the individual-fish counter.
