Drifting and Moored FADs are widespread in the AtlanticPacific and Indian ocean purse seine fisheries. They catch over 1 million tons of tuna (nearly one-third of the global tuna total) and over 100,000 tons of by-catch in the vicinity of FADs as of 2005. 


Skipjack Katsuwonus pelamis, Bigeye tuna Thunnus obesus and yellowfin Thunnus albacares tuna are the three primary tropical tuna species that FADs target. Other fish include albacoredolphin fishwahooblue marlinstriped marlinmako sharksilky sharkwhitetip sharkgalapagos shark, mackerel, and bonito.

Before FADs, pelagic purse seiners targeted free-swimming schools of tuna. 

The U.S. state of Hawaiʻi operates 55 surface FADs around its islands to support sport fishing and marine research.
