Notes
1. Source of production tonnage: FAO FishStat "Aquaculture Production (Quantities and values) 1950-2017 (Release date: 25th March 2019)".
2. Source of estimated mean weights (EMWs) : as for our earlier estimate, see Estimating the Number of Farmed Fish Killed in Global Aquaculture Each Year.
3. The estimated numbers are calculated as the production tonnage divided by estimated mean weight (EMW) where a mean weight has been estimated for the species.
4. The fish numbers for species without an estimated mean weight (EMW) have not been estimated for each individual species or country.
