Albacore stocks in the north Atlantic are assessed by the International Commission for the Conservation of Atlantic Tunas (ICCAT). The most recent assessment of the stock was carried out in 2016 using data up to 2014 and indicated that the stock was not overfished (B2015 at 1.36BMSY) or subject to overfishing (Fishing mortality, F2014at 0.54FMSY). Preliminary 2018 catch was 29,363t, higher than the recent average (around 27,000t) but below the 2018 Total Allowable Catch (33,600t) and Maximum Sustainable Yield (37,082 t). There is a Multi-Annual Plan in place for North Atlantic Albacore, which has the objective of maintaining the stock in a good state with at least 60% probability. Following a review and provision of advice by the scientific committee in 2017, the plan is now supported by a Harvest Control Rule with MSY-based targets and limits. The Harvest Control Rule is expected to maintain the stock in a good state with at least 60% probability. Since the establishment of the TAC in 2001, catch has remained substantially below the limit in all but four years, which might have accelerated rebuilding over the last decade. Since 1999, there has been a limit on the number of vessels in the fishery which appears to have reduced mortality.
Approximately 36% of the albacore from the North Atlantic is caught in pole and line surface fisheries which are selective yet rely on large amounts of live bait fish. Whilst the scale of this is unlikely to overexploit stocks of these species, it could have implications for local availability.
Tuna belong to the family Scombridae. They are large, oceanic fish and are seasonally migratory, some making trans-oceanic journeys. Albacore are found throughout the world’s temperate, sub-tropical and tropical oceans, although they are less common in the tropics. They are found from the surface to a depth of 600m where they often form mixed schools with skipjack, yellowfin and bluefin tuna. They grow more slowly than skipjack and yellowfin tuna, reaching a maximum size of 140cm, 60kg in weight and maximum age of 15 years. Albacore mature when about 90cm length and 4-5 years old. Spawning normally occurs between January and July.

Albacore stocks in the north Atlantic are assessed by the International Commission for the Conservation of Atlantic Tunas (ICCAT). Scientific studies on stocks in the North Atlantic, North Pacific and the Mediterranean, suggest that environmental variability may have a serious potential impact on albacore, affecting fisheries by changing the fishing grounds as well as productivity levels and potential Maximum Sustainable Yield. This could explain recent changes, e.g. the lack of availability of albacore in the Bay of Biscay in some years, or the apparent decline in the estimated recruitment.
The most recent assessment of the stock was carried out in 2016 using data up to 2014. As with previous analyses, the model indicates that spawning stock biomass decreased between 1930 and the 1990s, and was in an overfished state in the 1980s and 1990s. It has recovered since then, and fishing mortality has decreased. While biomass, B, is estimated to be above Maximum Sustainable Yield (B2015/BMSY = 1.36), there are concerns that this might be overestimated. Fishing effort, F, is below (F2014/FMSY = 0.54). The probability of the stock currently not being overfished and not undergoing overfishing is 96.8%. The next stock assessment is due in 2020.
After peaking at 60,000 tonnes in the 1960s, landings of northern albacore declined to 37,000t in 2006 and reached the historical minimum of around 15,000t in 2009. Preliminary 2018 catch was 29,363t, higher than the recent average (around 27,000t) but below the 2018 Total Allowable Catch (33,600t) and Maximum Sustainable Yield (37,082 t). The Harvest Control Rule adopted in 2018 is expected to maintain the stock in a good state with at least 60% probability. Since the establishment of the TAC in 2001, catch has remained substantially below the limit in all but four years, which might have accelerated rebuilding over the last decade.
Northern albacore are targeted by fisheries which take mainly immature and sub-adult fish, which could have implications for the stock. The scientific committee’s ability to monitor changes in stock abundance is currently limited due to incomplete fishery dependent information, and alternative fishery independent data is needed to address this.

Most tuna stocks range across and are accessed by numerous coastal states, making harmonised and effective management of these individual stocks very difficult. To try and address this, Intergovernmental Regional Fisheries Management Organisations (RFMOs) have been established. There are five main tuna RFMOs worldwide and it is their responsibility to carry out data collection, scientific monitoring and management of these fisheries. This stock is managed and assessed by the International Commission for the Conservation of Atlantic Tunas (ICCAT). Whilst the RFMOs are responsible for the development of management and conservation measures, the degree to which they are implemented, monitored and enforced still varies significantly between coastal states. There remain large data deficiencies in most tuna and billfish fisheries, particularly with regards to fine scale spatial and temporal data for both target and especially for vulnerable bycatch species. For this reason, it is important to choose tuna that has been caught by vessels that are well regulated by their flag state.
There is a Multi-Annual Plan in place for North Atlantic Albacore. Following a review and provision of advice by the scientific committee in 2017, the plan is now supported by a scientifically robust (according to a peer-review in 2018) Harvest Control Rule with MSY-based targets and limits. It is expected to maintain the stock in a good state with at least 60% probability. The management plan includes the following measures:
The TAC (Total Allowable Catch) in 2017 is 28,000 t, with individual catch limits assigned to each country. This increases to 33,600 t for 2018-2020.
Since 1999, capacity has been limited to the average number of vessels from 1993-1995. The effect of this has not been evaluated but a general decrease of fishing mortality has been observed since its implementation.
ICCAT maintains a list of vessels over 20m authorised to fish for these species, although other vessels may retain them as bycatch as long as the country sets limits on this and doesn’t exceed its quota.
Other management measures of note include:
In 2019 ICCAT increased observer coverage: large purse seiners targeting tropical tunas must have 100% coverage year round rather than just during the FAD closures, and longline coverage will increase from 5% to 10% in 2022. However, the 5% coverage was not well complied with or enforced by some fleets (although others exceeded it), and even this increase falls short of recommendations for a minimum of 20% for accurate reporting of bycatch. However, standards for electronic monitoring are to be developed by 2021. Purse seine and longline vessels over 20m long are encouraged to increase their observer coverage from the required minimum, and some have. Vessel Monitoring Systems are required for all vessels over 24m.
Drift nets are banned in the Mediterranean.
ICCAT maintains lists of vessels authorised to fish for tuna and tuna-like species in the ICCAT area, and those caught carrying out Illegal, Unreported or Unregulated activities.
At-sea transhipment is prohibited unless pre-authorised and the vessel has an observer on board.
In 2017 ICCAT banned the discarding of skipjack, yellowfin and bigeye.
In 2016 the Commission passed measures to strengthen and streamline its compliance assessment process and to develop a scheme of responses to non-compliance.

Approximately 36% of the albacore from the North Atlantic is caught in pole and line surface fisheries. These fisheries are mainly EU fleets from Spain, with lesser catches from Ireland, France and Portugal in the Bay of Biscay, in the adjacent waters of the northeast Atlantic and in the vicinity of the Canary and Azores Islands in summer and autumn. The surface fisheries (troll and pole & line) generally target smaller (50 to 90cm FL) and younger fish, but are a very selective method of fishing and have minimal impact on bycatch species. There has been some concern raised over the demands placed on bait fish populations, but these impacts have not been assessed. Whilst bait fish species are generally quite resilient, it is important to ensure their use in these fisheries sustainable.
