Estimated by A Mood and P Brooke, Sep 2019.   Updated Nov 2019 for Rainbow trout, see note 5 below.

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.
5. For rainbow trout, a weighted estimated mean weight has been used based on the proporation of small rainbow trout (< 1200g) and large rainbow trout (> 1200g) produced in the country, if available. See FEAP data.
(The estimated mean weight (EMW) for rainbow trout is 210-5000g and the EMWs for small and large rainbow trout are therefore respectively 210-1200g and 1200-5000g.)
Global estimated numbers for rainbow trout based on these weighted estimated mean weights total 268-3072 million individuals as compared to 162-3865 million based on the (unweighted) estimated mean weight of 210-5000g.
