Very low risk
Albacore tuna in the South Pacific has been scored a low risk. The biomass of albacore tuna in the South Pacific has remained stable over the past 20 years. The biomass is considered to be healthy and fishing mortality rates are currently sustainable.
The management of South Pacific albacore has been scored a low risk. Albacore in the South Pacific are managed by the Inter-American Tropical Tuna Commission (Eastern Pacific Ocean) and Western and Central Pacific Fisheries Commission (Western and Central Pacific Ocean). There is a limit reference point for South Pacific albacore and interim target reference point but no harvest control rule. Few management measures specific to this species have been adopted. However, populations appear to be healthy at this time. So we have awarded a low risk score.
The bycatch in the albacore tuna South Pacifc Ocean troll fishery 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 trolling occurs at the surface and do not come in contact with bottom habitats.
