This fishery is run by international producer Tri Marine, with 10 American Samoa-based purse seiners targeting skipjack and yellowfin tuna.
Skipjack are a highly productive tuna exhibiting great variability in life history characteristics. They grow up to a metre in length, and gather in surface shoals of up to 50,000 individuals. They reproduce at a greater rate than other species of tuna, and are responsible for more than half the world tuna harvest.
Yellowfin are fast-moving and wide-ranging pelagic predators. They spend the majority of time in the top 100m, but make occasional deep dives to much greater depths. They are one of the larger species, reaching weights above 180kg, but often mix with other tuna. Schools of small yellowfin and skipjack are common.
The purse seines used in this fishery are not associated with fish aggregating devices. Stocks are conserved by permitting vessels only a limited number of days at sea each year – the vessels in this UoC were allocated 2000 days in 2014 – and with no-fishing zones. Observer coverage and log books are mandatory, along with catch reporting.
