This is a list of aquatic animals that are harvested commercially in the greatest amounts, listed in order of tonnage per year (2012) by the Food and Agriculture Organization. Species listed here have an annual tonnage in excess of 160,000 tonnes.

This table includes mainly food fish species, but also listed are crustaceans (crabs and shrimps), cephalopods (squids and cuttlefishs), bivalves, and a reptile (softshell turtle).

Note that Oreochromis niloticus and Penaeus monodon appear twice, because substantial amounts are harvested from the wild as well as being extensively raised through aquaculture.
