The following studies estimate the numbers of fish killed globally each year in fishing and fish farming, using FAO fisheries capture and aquaculture production tonnages together with estimated mean weights for fish species. It is estimated that, each year:
970 – 2,700 billion fishes are caught from the wild, of which
450 – 1,000 billion fishes are caught to make fishmeal and fish oil.
37 – 120 billion farmed fish are killed for food.
170 – over 400 billion farmed decapod crustaceans are also killed for food.
