This page shows aquaculture production tonnages (FAO) for decapod species in 2016, together with estimated mean weights (EMWs) and estimated decapod numbers.
Farmed decapod numbers killed for food in 2016 are estimated to total 230,105-550,310 million, or 230-550 billion, individuals.
This includes 5-15 billion crabs; 28-45 billion crayfish and lobsters and 197-490 billion shrimps and prawns.

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 described in our earlier estimate for fishes, 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 category.
4. The decapod numbers for species without an estimated mean weight (EMW) have not been estimated for each individual species. Total numbers for such species combined are estimated from
the generic estimated mean weight (GEMW)5, as described for our earlier estimate (note 2).
5. The generic estimated mean weight (GEMW) is obtained as the total tonnage for single-species categories with an estimated mean weight (EMW) divided by the total estimated numbers for these species.   In other words, it is assumed that the mean weight of decapods for species without an EMW is equal to the overall mean weight of decapods for single-species categories with an EMW.
