Very low risk
Albacore in the North Atlantic has been scored a low risk. The spawning stock biomass (SSB) has recovered to levels above the level associated with maximum sustainable yield BMSY. Current fishing mortality rates (F2014) are 54% of those needed to produce the maximum sustainable yield (FMSY). Therefore the population is not considered overfished and overfishing is not occurring. We have awarded a low risk because the biomass has recovered and fishing mortality rates are sustainable.
The management of North Atlantic albacore has been scored a low risk. The International Commission for the Conservation of Atlantic Tuna (ICCAT), in charge of management of albacore in the North Atlantic, has adopted a scientifically based total allowable catch. Catches have remained well below the TAC for most years and this has likely aided in the rebuilding of this species. In 2017, ICCAT adopted an interim harvest control rule for albacore in the North Atlantic.
The bycatch in the albaocre tuna North Atlantic Ocean troll, and pole and line fisheries has been scored a low risk. Bycatch and discards in troll and pole and line fisheries typically makes up a small proportion of the total catch (Kellher 2005). Baitfish are typically used in troll and pole fisheries. The ratio of tuna to baitfish is around 30:1 and in most cases baitfishing makes up a small proportion of the total fishing mortality for baitfish species (Gillet 2012).
The seabed effects of the fishery are scored a very low risk. This is because troll and pole and line fish at the surface and do not come in contact with bottom habitats.
