Updated: December 2019
Haddock biomass from the Rockall region has increased five-fold in the last five years. The stock is in a healthy state and is well above any warning reference points such as BMSY Trigger or BMSY limit. The stock recruitment has been increasing since 2008-2011 period, from an all time low, but is still below average. Fishing mortality has strong fluctuations but has, in general, been declining in recent years. Fishing mortality has hovered around FMSY for the last few years and in 2018 was estimated to be below the FMSY. There is no haddock-specific management plan for haddock in this area (excluding MSC Rockall haddock), though the EU multi annual plan (MAP) for Western Waters does cover this stock. This is a recently implemented management plan (2019/2020) and so the effectiveness is currently undetermined. Most haddock (99.6%) in this area is caught by otter trawling, over a mixture of substrates, including rocky reefs and boulders. There is limited information on bycatch, and no records of marine mammal bycatch, but there are some concerns over catch of vulnerable species such as skates and sharks. Habitat impacts of longlining (0.4% of catches) are low, but there is potential for bycatch of Endangered, Threatened and Protected species such as sharks and seabirds. However, there is some uncertainty surrounding the levels of bycatch of such species. There are areas in Rockall with protective measures in regards to vulnerable habitats and haddock spawning.
Haddock is a cold-temperate (boreal) species. It is a migratory fish, found in inshore shallow waters in summer and in deep water in winter. Smaller than cod, it can attain a length of 70-100 cm and can live for more than 20 years. It spawns between February and June, but mostly in March and April. In the North Sea, haddock become sexually mature at an age of 3-4 years and a length of 30-40 cm. Maturity occurs later and at greater lengths in more northern areas of its range.

The Rockall haddock stock is healthy with no overfishing. This stock is separate from the haddock stocks around the UK continental shelf, and has lower growth rates and a smaller maximum size.
The spawning stock biomass in 2019 was the highest value since 1991, a big improvement from 2014, when it was the lowest on record. Recruitment has improved steadily since 2011, though is expected to still be below average in 2019 and 2020. Fishing mortality has slowly been reducing since the 1990s, and the last few years have seen the lowest fishing mortality, though it still is hovering around the FMSY. In 2012 and 2016 F was below FMSY, but from 2013-2015, and again in 2017, F was above FMSY. In 2018 F was again below FMSY (F/FMSY = 0.96).
The discards for haddock are relatively small, certainly compared to historical values. During the 1990s haddock discards were often double the landings or more. The 2019 discard estimates are around 13% of total haddock catch, which is similar to the last 5 years (8-17% annual discard rate). The selectivity of longlines in hook size usually means juveniles are less likely to be caught in that fishery.
The advice for catch under the MSY approach is 10472 tonnes, a marginal increase from the 2019 advice (10469 tonnes).
The Scottish industry observer sampling scheme has tried to improve coverage in this area, though haddock samples remain low. More sampling opportunities are being hoped for in the future.

Haddock in this area is not overfished or undergoing over fishing and discard rates have been reducing steadily. It is covered by new management measures (EU Western Waters Multi Annual Plan, MAP), regulations over international waters have been put in place and landings have been consistently in line with TAC recommendations. Improvements have been made, but the effectiveness of this remains to be seen.
Scotland is the main country fishing for Rockall haddock, with Ireland and Norway the second and third largest. Other countries such as Russia and Faroe Islands occasionally land haddock from this region.
Under a recent robust analysis, all of the harvest control rules have been shown to be precautionary in the short, medium and long term except for in circumstances of consistently low recruitment over a prolonged period of time. Therefore management is largely considered to be precautionary. The recommended Total Allowable Catch has been adhered to since the implementation of the Maximum Sustainable Yield (MSY) approach in 2014. There is a minimum landing size of 30 cm. However, while this TAC has been adhered to, it only covers European waters. As part of this sub-region is in international waters this means regulations such as catch and minimum landing size do not apply to international vessels, such as Russian trawlers which have been known historically (early 2000s) to fish heavily in this region. However a number of protocols have been put in place, such as closed areas to fishing (except for longlines) to protect juvenile haddock and cold water corals, and a discard ban has been in place in the North East Atlantic Fisheries Commission regulatory area since 2009.
While there is no haddock-specific management plan, this stock now comes under the EU Multi Annual Plan (MAP) which is being implemented across 2019-2020. The effectiveness of such a plan is currently unknown.
In the European Union (EU), EU fishing vessels can fish up to 12 nautical miles of any Member State coast, and closer by agreement. There is overarching fisheries legislation for all Member States, but implementation varies between fisheries, Member States and sea basins.
The EU Common Fisheries Policy (CFP) is the primary overarching policy. Its key environmental objectives are to restore and maintain harvested species at healthy levels (above BMSY), and apply the precautionary and ecosystem-based approaches to fisheries management. To achieve the MSY objective, the MSY exploitation rate is supposed to be achieved by 2020, but this seems unlikely to happen.
The CFP also introduced a Landing Obligation (LO) which bans the discarding at sea of species which are subject to catch limits. Some exemptions apply to species with high post-capture survival, and where avoiding unwanted catches is very difficult. These exemptions are outlined in regional discard plans. Despite quota ‘uplift’ being granted to fleets under the LO, available evidence suggests there has been widespread non-compliance with the policy, and illegal and unreported discarding is likely occurring.
Multi-Annual Plans (MAPs) are a tool for implementing the CFP regionally, with one in place or being developed for each sea basin. They specify fishing mortality targets and ranges for the main targeted species, as well as lower biomass reference points. If populations drop below these points it should trigger a management response. The MAPs also empower Member States to jointly apply measures such as closures, gear or capacity limits, and bycatch limits. There is concern however that the MAPs do not provide adequate safeguards to maintain all stocks at healthy levels.
The EU Technical Measures regulation addresses how, where and when fishing can take place in order to limit unwanted catches and ecosystem impacts. There are common measures that apply to all EU sea basins, and regional measures that vary between sea basins. Measures include Minimum Conservation Reference Sizes (MCRS, previously Minimum Landing Sizes, MLS), gear specifications, mesh sizes, closed areas, and bycatch limits.
The Control Regulation, which is being revised in 2019, addresses application of and compliance with the above, e.g. keeping catches within limits, recording and sharing data, and satellite tracking of vessels over 12 metres (VMS).

Habitat impacts of longlining are low, but there is potential for bycatch of Endangered, Threatened and Protected species such as sharks and seabirds. However, there is some uncertainty surrounding the levels of bycatch of such species.
Longline fishing is seen as a more environmentally friendly fishing approach than trawling, as the passive nature means fewer impacts on the seabed (except for when the lines are surfaced, when minor damage may occur). Haddock landings via longline represent 0.4% of total landings, which equates to 15.5 tonnes. The longline landings of haddock are bycatch from the Norwegian longline fishery (Norway landings: 16 tonnes) which is certified for ling and tusk. Haddock bycatch typically represents 1-4% of the longline certified fishery landings, though this does cover subareas 1, 2, 6, 7, 8, 9, 12, 14, divisions 3a and 4a so the specific haddock bycatch proportion in the Rockall region is unknown. Given the healthy state of the stock, it is unlikely that longline is having any impact on the haddock stock. Ling and tusk stocks in the assessed areas are not of concern, though the data is somewhat limited.
The impact the longline fishery has on birds is highly uncertain, with data reliability judged as ‘poor’ a number of years ago (2011). More recently it was noted that no seabird bycatch data is available for this fishery, though key milestones include implementing a recording system for birds (both Endangered, Threatened and Protected species and non-ETP species). Estimates of bird bycatch on the Norwegian demersal longline fishery vary considerably, from 1,177 to 101,380 birds on an annual basis. Again the spatial resolution does not go down to subarea 6b level. Therefore it is difficult to project the impact on any ETP birds. Within the ling and tusk certified fishery, where this haddock is most likely from, it has been noted that longline methods are not likely to hinder any recovery of ETP species. However, better recording of ETP landed species is on the fishery agenda. An experimental study at the Hatton Bank suggested that longline fishing can catch a number of vulnerable deep water sharks, however until proper records are in place, there is a level of uncertainty associated with this.
A number of closed areas, established on the Rockall and Hatton Banks in 2006 and the Darwin Mounds to protect cold-water corals, may potentially provide further incidental protection for haddock stock. In area 6b, there are some designated areas: fishing is closed in multiple areas around the Rockall Bank including the Northwest and southwest Rockall Bank area and the Haddock Box (except for longline). The former two are closed to protect Vulnerable Marine Ecosystems (VMEs) and the latter to protect haddock stocks.
