Using the same method as that used to estimate farmed fish numbers, the numbers of decapod crustaceans killed in recorded aquaculture production in 2015 have been estimated as follows:

  • 30-56 billion* crayfish, crabs and lobsters
  • 190-470 billion shrimps and prawns.

Details of the estimate are available for global production and by country and by species. Welfare issues in crustacean farming include inhumane methods of killing, live marketing and long distance transport. Breeding stock of shrimp and prawn species are subjected to eyestalk ablation to increase egg production. See Welfare of crustaceans.
