Very low risk
Atlantic Ocean yellowfin tuna has been scored a moderate risk. This is because the stock biomass is only slightly below levels necessary to produce the maximum sustainable yield but fishing mortality rates are sustainable.
The management of the yellowfin tuna Atlantic longline fishery is moderate risk. The population remains overfished but current management methods aim to allow the population to rebuild by 2024. Surveillance and enforcement is mainly good, although not all countries routinely comply.
There is no adopted target reference point, although work towards developing a limit reference point and harvest control rule is being conducted.
The bycatch in the yellowfin tuna Atlantic troll and pole fishery has been scored a low risk. Bycatch and discards in troll and pole fisheries typically makes up a small proportion of the total catch (Kellher 2005). However, baitfish are often used in these fisheries. The ratio of tuna to baitfish is around 30:1 (Gillet 2012).
The habitat impact of the yellowfin tuna Atlantic Ocean pelagic troll and pole fishery has been scored as low impact. This is because there is the potential for hooks to contact bottom habitats. Although in tuna fisheries, which target fish in open waters, this is a very minor concern.
