Aquaculture is the most rapidly expanding food industry in the world [7] as a result of declining wild fisheries stocks and profitable business. [2] In 2008, aquaculture provided 45.7% of the fish produced globally for human consumption; increasing at a mean rate of 6.6% a year since 1970.

The albacore is a powerful, hard-hitting predator [4] that forms mixed schools with skipjack tuna, yellowfin tuna, and bluefin tuna, sometimes around floating objects like sargassum weeds.
