It is estimated that between 51 and 167 billion* (ie 51,000,000,000 – 167,000,000,000) farmed fishes were slaughtered for food globally in 2017 which represents a 4-6% increase since 2015, during which an estimated 48 to 160 billion* were slaughtered. This is an update to an earlier estimate of between 37 and 120 billion* farmed fishes slaughtered for food globally in 2010 and details of the estimating method are given in the pages below.

Details of the estimate are available for global production and by country and by species.
