Atlanto Scandian Herring Fisheries Management Plan
The Atlanto Scandian herring (ASH) Fisheries Management Plan (FMP) is one of 43 FMPs set out in the Joint Fisheries Statement (JFS).This FMP sets out the policies and actions to manage the Atlanto-Scandian herring (ASH) stocks at sustainable levels.
FMP policies
In developing the policies and actions for this FMP, the fisheries policy authorities have considered the current policy landscape including applicable international agreements and declarations, conservation advice and wider policy development already underway, in addition to considering what additional evidence, measures or policies may be needed to support both the vision of this FMP and delivery of the Fisheries Act 2020 objectives. In most cases, individual actions within this FMP will directly link to one or more of the Act’s objectives and these links are made below. FMPs are one of the tools that support the achievement of the fisheries objectives, although they are not the only policy vehicle available to do this. The fisheries policy authorities have also considered the conservation advice received from the SNCBs and included the outputs from that work in considering where policy action may be needed.
Effective management of the overall marine space is critical to sustainable development of existing and emerging sectors, and the protection of the marine environment. Whilst not a specific topic that is covered in detail within the FMPs, the fisheries policy authorities are working on a range of policies to help manage the increased demand for marine space, reduce the conflict arising from competition for marine space, and ensure that the right protections are in place to manage broader impacts from wider use. This FMP has been developed within the wider context of the relevant Marine Plans around the UK. Consideration will also be given to the objectives and principles outlined in the EU-UK Trade and Cooperation Agreement when considering measures.
In Scotland, these policies will help achieve the outcomes set out in the Good Food Nation Plan[41], and its vision of Scotland becoming ‘a Good Food Nation, where people from every walk of life take pride and pleasure in, and benefit from, the food they produce, buy, cook, serve, and eat each day’
In most cases further policy development work will be needed for any new actions, which could include additional evidence gathering or public consultation, along with the completion of appropriate impact assessments. It should also be noted that ASH is a jointly managed stock, and therefore overall fishing opportunities are determined through international negotiation. The stock is also subject to different management measures in different areas of the sea by individual Coastal States. As most fishing for ASH by UK vessels takes place outside of UK waters, measures contained within this FMP relating only to UK waters may not be applicable elsewhere.
The most recent ICES advice, alongside the fact that there is no-sharing arrangement in place, underlines the importance of international negotiation and cooperation in ensuring the development and delivery of effective management measures for ASH.
The first two policies set out below largely relate to management measures to achieve long-term sustainability of the ASH stock, and the remaining policies set out actions in relation to wider sustainable management.
Policy 1: Harvest the ASH stock sustainably, contributing to maintaining or restoring the biomass above the level capable of producing MSY
Rationale
The primary aim of FMPs, such as this ASH FMP where there is sufficient available scientific evidence to enable assessment of a stock’s MSY, is to set out policies designed to maintain or restore the fish stocks at sustainable levels. This is in line with section 6(3)(a) of the Fisheries Act 2020, where the role of fisheries managers is to help ensure stocks are harvested sustainably, in order to protect the long-term viability of the stocks and the fisheries that depend upon them.
The use of TACs as a measure to manage fisheries is a key approach adopted by the UK and coastal states to help ensure that the fishing pressure on ASH is kept within sustainable levels, whilst also taking account of relevant socio-economic factors. This is consistent with the sustainability objective of the Fisheries Act 2020.
As already noted elsewhere in this FMP, the ASH stock has seen fluctuations over recent years. The SSB on 1 January 2026 is estimated by SAM to be 3.012 million tonnes which is below Bpa (3.177 million t). The spawning stock has been declining since 2009 but increased in 2021 and 2022 followed by a decrease again in 2023 to 2025. The newly benchmarked assessment of NSS herring leads to a somewhat revised perception of the stock. The estimated SSB in 2024 was 5% lower in this year’s assessment compared to last year; further back in time the difference was larger. In the last 30 years, several large year classes have been produced (1998, 1999, 2002, 2004 and 2016). The year classes 2005-2015 and 2017-2019 are estimated to be average or small. Results from surveys in the Barents Sea the last two years have estimated the size of the 2021 and 2022 year-classes as being above average. Fishing mortality in 2024 is estimated to be 0.156 which is above the management strategy F (0.14) but below FMSY and Fpa (0.21).
The UK fisheries policy authorities are broadly confident that the ASH stock can continue to be managed through the use of TACs. Implementation of REM in March 2026 will enhance monitoring of catches, further supporting the use of a TAC management approach. The actions below are therefore focussed on maintaining the current management approach, whilst also delivering improvements by progressing sharing discussions in the international fora.
Actions
Ongoing actions
- Continue to take an approach to TAC setting informed by the best available scientific advice and in line with the LTMS.
Short term actions
- Following the ICES benchmark for the stock in 2025, progress coastal State discussions to refine and update the current LTMS
Relevant Fisheries Act objectives
The relevant objectives are the:
- sustainability objective
- precautionary objective
- scientific evidence objective
- ecosystem objective
- national benefit objective
Policy 2: Use the best-available scientific evidence to support management decisions relating to the setting of sustainable fishing opportunities
Rationale
This policy is in accordance with section 3.2 (‘Science and Evidence’) of the JFS.
Scientific evidence is essential for delivering appropriate and sustainable fisheries management. A considerable level of work is carried out at national and international level to ensure that the scientific evidence base is robust and up to date.
ASH has a robust level of scientific evidence and data in place which already enables fisheries policy authorities to make an MSY assessment for the stock and to take evidence-based decisions in relation to the setting of fishing opportunities.
The actions below are focussed on maintaining the current data collection and scientific approach, along with considering longer-term improvements.
Some actions are not specific to the ASH stock but are general actions which underpin the UK’s overall approach to collection and use of scientific data to support fisheries management.
Actions
Ongoing actions
- Continue to participate in ICES working groups to support ongoing data collection and maintenance of the international scientific evidence base that supports the setting of fishing opportunities at sustainable levels.
- Continue to undertake scientific surveys, participate in international stock assessments and contribute to the international advice process.
- Continue to work collaboratively with the UK pelagic industry in the Scottish Pelagic Industry-Science Data Collection Programme (SPISDCP) allowing data to be gathered on a haul-to-haul basis ensuring that high quality representative, data are gathered and submitted to ICES.
- Continue to use the best available evidence to underpin management decisions, implementing the precautionary approach when robust data is not yet available.
Short term actions (one to two years)
- Utilise additional and new data streams, including the use of biological data from the self-sampling scheme of the SPISDCP and scientific data derived from new technology such as REM.
Relevant Fisheries Act objectives
The relevant Fisheries Act objectives are the:
- sustainability objective
- scientific evidence objective
- precautionary objective
Policy 3: Monitor catches of ASH and ensure that where possible all catches are counted against quotas
Rationale
This policy is in accordance with section 4.2.8 (‘Reducing Bycatch and Minimising Catches of Sensitive Species’) of the JFS.
Pelagic fisheries are, in the main, classed as a relatively clean fishery, meaning that issues with discarding and bycatch are deemed to be minimal. Given the capability of pelagic trawl vessels to take large tonnage hauls, the impact of any discarding/slipping, should it take place, would be considered high.
There is a legislative requirement under the landing obligation to land all species of fish subject to quota regulations, and for fishers to ensure that all catches are counted and recorded. From 7 March 2026, all pelagic fishing vessels fishing in Scottish waters and all Scottish pelagic vessels wherever they fish, must have REM on board. REM is an effective way of ensuring that fishing vessels comply with relevant fisheries legislation.
REM also supports fisheries managers to understand levels of fish bycatch within pelagic fisheries, and take appropriate action if needed. This is consistent with the action suggested within the pelagic conservation advice.
Actions
Ongoing actions
- Continue to monitor pelagic fishing activity using REM (where available) and other tools and take appropriate action to tackle non-compliance as needed.
- Continue to monitor levels of fish bycatch within pelagic fisheries and take appropriate management action if required.
Relevant Fisheries Act objectives
The relevant Fisheries Act objectives are the:
- bycatch objective
- scientific evidence objective
- sustainability objective
Policy 4: Identify and support implementation of ecosystem-based fisheries management approaches appropriate for the ASH fisheries
Rationale
This policy is in accordance with section 4 (‘Delivering Sustainable Management of Fisheries’) of the JFS.
A thriving fishing industry is underpinned by healthy and productive seas. As set out in the JFS and the Act, the UK and Scottish Governments are committed to an ecosystem-based approach to fisheries management that will account for, and seek to minimise, impacts on non-commercial species and the marine environment. This also links to existing initiatives such as the Bycatch Mitigation Initiative and Clean Catch UK.
Understanding and minimising these impacts is an important part of delivering an ecosystem-based approach. The fishing industry has taken a number of steps over previous years to try and mitigate against this, for example by using more selective fishing gears, or trialling new tools to reduce bycatch of non-fish species and seabirds. The conservation advice that supports this FMP has identified some impacts and evidence gaps that need to be addressed in order to ensure that the risk posed by pelagic fishing to the wider marine ecosystem is minimised. In particular, conservation advice has flagged the need for an improved evidence base around bycatch levels and a recognition of the need for greater understanding and identification of potential actions in relation to predator/prey interactions, given the importance of pelagic species in the marine food chain. In some cases, action is already being taken on this and there are a range of policies and initiatives already in place or in development across the UK which contribute to this.
Actions
Ongoing actions
- Continue to monitor levels of bycatch in pelagic trawl fisheries through REM, to improve understanding of risk and to support appropriate management if required.
- Continue to promote existing good practice within the fishing industry in relation to handling of sensitive marine species and returning them to the sea unharmed, where practical to do so.
Short-term actions (one to two years)
- Work with UK experts to consider the ecological role of pelagic species in the North Sea and West of Scotland, and how an ecosystem-based approach could be integrated into fisheries management.
Medium to long term actions (three to five years)
- Work with ICES to consider further developing ecosystem-informed assessments and ecosystem modelling approaches in the future
- Encourage and support initiatives to promote the consumption and value of ASH
Relevant Fisheries Act objectives
The relevant Fisheries Act objectives are the:
- sustainability objective
- ecosystem objective
- bycatch objective
Policy 5: Support fishing businesses to deliver socio-economic and cultural benefits for communities
Rationale
The UK Government holds an ambition to enable fisheries to continue to deliver social and economic benefit to coastal communities to benefit present and future generations. As already set out in this FMP, although ASH is not the main target fishery for pelagic fishing vessels in the UK, it does form a part of the business model for fishing businesses. In turn, these businesses collectively support jobs and underpin local communities, providing a source of economic input and output and underpinning the rich cultural heritage of the UK at both a local and national level. Fish is also a rich source of protein and forms an important component of food production within the UK.
There is an ongoing role for governments to help create the right conditions for businesses to operate sustainably and with certainty about the future.
Actions
Ongoing and short-term actions (one to two years)
- Continue to take account of socio-economic considerations as part of international negotiations and as part of the process to determine fishing opportunities.
- Continue to gather and use evidence on economic aspects of the fishery to ensure management decisions are informed by the best available evidence.
Relevant Fisheries Act objectives
The relevant Fisheries Act objectives are the:
- equal access objective
- national benefit objective
- sustainability objective
Policy 6: Reduce the impact of fishing on climate change and support the fishing industry to adapt to the impacts of climate change
Rationale
This policy is in accordance with section 4.1 (‘Delivering Sustainable Management of Fisheries - Our approach to Fisheries Management’) of the JFS.
The evidence base underpinning climate change and fisheries is developing, and more work is needed to fully understand a) how carbon emissions can be reduced in a sustainable way, and b) the likely impacts of climate change on fish stocks and fishing communities and the scale / nature of change required to adapt.
We know that there will be changes to the distribution and size composition of the ASH stock as a result of climate change, but the overall impacts are not yet fully understood. The actions below consider how we can build and use an improved evidence base in order to make informed decisions on management action for the future.
In comparison to other forms of food production, fishing can provide a high-protein and low carbon method of production and offers opportunities to provide food security particularly as we move towards net zero. However, we also know that fishing vessels need to reduce fuel emissions in the future although there are no ready solutions in place for fishing vessels to currently utilise.
The actions set out below will also apply to other stocks in the fishery. However, as our evidence base grows, we will understand better the specific impacts of climate change on ASH, and the scale of change required to support vessels fishing for ASH to reduce their emissions and also adapt to changes in the ASH stock and general fishing conditions. These actions are likely to adjust over time and will become more refined.
Possible measures which could support this are already in development and / or being delivered. The FMP will support these measures, although it is not directly introducing or delivering them.
Actions
Medium to long term actions (three to five years)
- Collaborate with partners across government, industry, and academic sectors on initiatives to reduce environmental impacts of the ASH fishery (including CO2 emissions) ) through projects such as the Horizon Europe project “Measures for Climate Change Adaptation and Mitigation in European Fisheries (MeCCAM)[42].
- Collaborate across the UK and internationally on further evidence and analysis to understand the impact of climate change on ASH and develop options for how the ASH fishery may adapt to climate change impacts in the future.
- As additional information becomes available in relation to climate change, explore the implications for this.
