Scottish salmon farm medicine significantly impacting local marine environments as SEPA unveils firm, evidence-based proposals for a revised regulatory regime

Scottish salmon farm medicine is significantly impacting local marine environments. That is the conclusion of one of Scotland’s largest and most comprehensive marine research projects into aquaculture, undertaken by the Scottish Environment Protection Agency (SEPA).

  • Scottish salmon farm medicine significantly impacting local marine environments concludes SEPA research report, which increases the now substantial weight of scientific evidence that the existing approaches do not adequately protect marine life.
  • SEPA announces firm, evidence-based proposals for a revised regime that will strengthen the regulation of the sector.
  • New, tighter standard for the organic waste deposited by fish farms.
  • More powerful modelling using the best available science, replacing 15 year old framework.
  • Enhanced environmental monitoring and creation of new SEPA enforcement unit to ensure compliance is non-negotiable.
  • New interim approach for controlling the use of Emamectin Benzoate, pending UK Technical Group recommendations to Scottish Government.
  • New approach could allow for larger farms than traditionally approved, provided they are appropriately sited in sustainable locations.
  • Scotland-wide consultation events across November and December.

Scottish salmon farm medicine is significantly impacting local marine environments.  That is the conclusion of one of Scotland’s largest and most comprehensive marine research projects into aquaculture, undertaken by the Scottish Environment Protection Agency (SEPA).

The survey, ‘Fish Farm Survey Report – Evaluation of a New Seabed Monitoring Approach to Investigate the Impacts of Marine Cage Fish Farms’, undertaken by specialist marine scientists using research vessel the Sir John Murray, examined environmental impacts from eight Scottish fish farms.  302 chemical samples were analysed from 93 sample stations and 296 ecological samples from 142 sample stations.

Samples for chemical analysis were analysed for the sea lice medicine Emamectin Benzoate (EmBz) and Teflubenzuron (Tef), last used in 2013.  The medicines were detected in 98% and 46% of samples respectively, with residues more widely spread in the environment around fish farms than had previously been found.  Moreover, the research concluded that the impacts of individual farms may not be contained to the vicinity of individual farms.

The research survey was published today (Wednesday, 7th November) as part of proposals by SEPA, one of a number of organisations regulating finfish aquaculture*, for a revised regime that will strengthen SEPA’s regulation of the sector.  The proposals follow 16 months of work by the agency, including a 2017 consultation, and two Scottish Parliamentary committees, one of which concluded that “the status quo is not an option”, adding that the industry’s expansion goal “will be unsustainable and may cause irrecoverable damage to the environment” unless governance and practices are improved markedly.

Scotland is the largest Atlantic salmon aquaculture producer in the European Union and third in the world after Norway and Chile.  A contributing factor to this is Scotland’s reputation for a high quality environment and abundant freshwater resources.

SEPA’s draft Finfish Aquaculture Sector Plan is ambitious in its aspirations for an industry where in the future:

  • The Scottish finfish aquaculture sector recognises that protecting the environment is fundamental to its success and is foremost in all its plans and operations.
  • The sector is a world-leading innovator of ways to minimise the environmental footprint of food production and supply.
  • The sector has a strong and positive relationship with neighbouring users of the environment and the communities in which it operates.  It is valued nationally for its contribution to achieving global food security.

It is also clear that all operators in the sector will reach and maintain full compliance with Scotland’s environmental protection laws, with SEPA working to help as many operators as possible to move beyond compliance.

Whilst SEPA’s latest Compliance Assessment Scheme (CAS) data saw overall compliance levels for the sector drop during 2017 to 81.14%, against a relative peak of 85.75% in 2016, the industry is innovating through the use of ‘non medicinal farming’ using wrasse, a small fish that tackles sea lice, full or partial containment and enhanced fallowing.

Specifically, SEPA’s firm, evidence based proposals for a revised regime that will strengthen the regulation of the sector include:

  • A NEW TIGHTER STANDARD FOR THE ORGANIC WASTE DEPOSITED BY FISH FARMS

Marine cage fish farming across Scotland operates using open-net cages.  Fish faeces; any uneaten food; used fish medicines and other chemical treatments escape from these cages into the marine environment.  The heavier, organic particles (the fish faeces and uneaten food) together with any medicines sticking to them are deposited on the sea floor.  Natural biological process then break down and assimilate the material over time.

The tighter standard limits the spatial extent of the mixing zone around farms.   The controls we will apply to these mixing zones will bring them into equivalence with modern practice on mixing zones for other waste effluent discharges into the sea, including those from urban waste water.

  • MORE POWERFUL MODELLING USING THE BEST AVAILABLE SCIENCE

The new regulatory framework will use new, more accurate computer modelling approaches that will improve our understanding of the risk to the local environment and allow assessment of the larger-scale impacts including interactions with other farms.

The science about fish farming is very complex and these new approaches will bring the aquaculture sector up to date with the modelling practices which are being used for other industrial sectors where there is a longer history of operation and analysis.

  • ENHANCED ENVIRONMENTAL MONITORING & NEW ENFORCEMENT UNIT

Operators will be required to invest in more accurate monitoring, including of waste coming from fish farms.  The creation of a new enforcement unit will strengthen the checking and verifying of monitoring that fish farm operators are required to undertake.  SEPA will also increase and strengthen monitoring of the impact of fish farms in surrounding areas.

  • NEW INTERIM APPROACH FOR CONTROLLING THE USE OF EMAMECTIN BENZOATE

SEPA has asked the UK Technical Advisory Group (UK TAG), a partnership of the UK environment and conservation agencies, to make recommendations on new environmental standards for Emamectin Benzoate to the Scottish Government.  UK TAG was established by the governments of the different parts of the UK to oversee the scientific process of developing the environmental standards used across the UK for protecting the water environment.

UK TAG is in the process of developing its recommendations.  This includes obtaining and considering independent scientific peer reviews of the evidence.  After UK TAG makes its recommendations to the Scottish Government, Scottish Government will consult on draft directions on the establishment of new environmental standards.

While this UK TAG work continues, SEPA will adopt a precautionary principle position which imposes a much tighter interim standard for the use of Emamectin Benzoate at any new site.  This is based on the now substantial weight of scientific evidence that the existing standards do not adequately protect marine life.  This interim standard will set a limit so low that it will, effectively, mean Emamectin Benzoate can only be discharged in very limited quantities at any new site.

  • NEW APPROACH TO SUSTAINABLE SITING OF FARMS

The combination of the new standard, the more accurate model and enhanced monitoring will allow the siting of farms in the most appropriate areas where the environment can assimilate wastes.  It will also allow SEPA to better match biomass to the capacity available in the environment and continue to assess that through the operation of the site. This may allow for the approval of larger farms than would have been traditionally approved previously, provided they are appropriately sited in sustainable locations.

Overall, the proposals will combine to encourage operators to site and operate their fish farms in environmentally less sensitive waters and use improved practices and technologies to reduce environmental impact.

In practice, we anticipate this will lead to fewer fish farms in shallower, slow-flowing waters and more fish farms in deeper and faster-flowing waters.  We also anticipate it will encourage the adoption of new technologies such as partial and full containment to capture organic waste and any remaining medical residues. SEPA has seen some industry operators successfully developing new approaches such as non-chemical ways of managing fish health. Our new regime will support these encouraging developments.

As one of a number of organisations regulating finfish aquaculture, SEPA believes its proposals have the potential to significantly improve in the environmental performance of the industry.

Recognising the diverse range of views of finfish aquaculture, SEPA is keen to hear directly from individuals, interest groups, NGOs, communities, companies and others with a view on the regulatory proposals.

As part of a seven-week public consultation, SEPA will embark on one of its most significant public engagement programmes to date.  SEPA will host a series of nine events across Scotland during November and December where people can find out more, talk directly with specialist teams and provide direct feedback as we strengthen our regulatory approach.

Terry A’Hearn, Chief Executive of the Scottish Environment Protection Agency, said:

 

Whilst a high quality environment and abundant freshwater resources are vital to Scotland’s aquaculture sector, it’s an industry that attracts polarised positions, from those who cite its economic contribution to those who stridently oppose its existence.

“As one of a number of organisations regulating finfish aquaculture, SEPA is clear that our job is to make sure environmental standards protect the marine environment for the people of Scotland and we make sure the industry meets those.  That’s unequivocally our focus.

“Consequently across the last sixteen months we’ve done more science, more analysis and more listening than ever before.   Whilst we’re seeing innovation in the sector, we’ve concluded that Scottish salmon farm medicine is significantly impacting local marine environments which increases the now substantial weight of scientific evidence that the existing approaches do not adequately protect marine life.

“We agree that ‘the status quo is not an option’ which is why we’re announcing firm, evidence based proposals for a revised regime that will strengthen the regulation of the sector.  As part of a Scotland-wide consultation, we’re now keen to hear directly from individuals, interest groups, NGOs, communities, companies and others on their views on the proposals as we move to strengthen our regulatory approach.”

Sector Plans

SEPA is changing today, creating a world-class environment protection agency fit for the challenges of tomorrow. By moving away from the traditional site by site regulation to grounding our regulation and activities across whole sectors, we will shape our interactions with every sector and the businesses in them.

Sector plans will be at the heart of everything we do and will help regulated businesses operate successfully within the means of one planet. In every sector we regulate, we will have two simple aims.

We will ensure that:

  • every regulated business fully meets their compliance obligations
  • as many regulated businesses as possible will go beyond the compliance standards.

SEPA has launched a new, dedicated space on its website for sector plans https://sectors.sepa.org.uk


Consultation Events

Further information on SEPA’s Finfish Aquaculture Sector Plan, including community consultation events, is available at https://sectors.sepa.org.uk.

* ‘Finfish’ are fish with fins as opposed to shellfish. Salmon, rainbow trout and brown trout are the main species farmed in Scotland.  ‘Aquaculture’ is the cultivation of freshwater or seawater organisms, including finfish or shellfish.

Watchdog calls for tougher controls on salmon farming

Polly Bartlett 7 November 2018

Current salmon farming practice is ‘significantly impacting marine life’ new study finds.

Salmon farms in Scotland could face tighter regulations.

The environmental watchdog Sepa found that the existing approach to salmon farming does not do enough to protect marine life, raising particular concerns about the chemical treatments for parasitic sea lice.

The tiny lice attach themselves to salmon and feed on them, killing or rendering them inedible.

Sepa tested waters for specific chemicals that were used to treat the sea lice until 2013, and found them to have a greater and longer-lasting impact on the environment than previously thought.

The proposed new restrictions will limit the future use of the chemicals and could mean some farms will have to relocate to deeper waters with stronger tides.

Terry A’Hearn, chief executive of Sepa, said: “Our job is to make sure environmental standards protect the marine environment for the people of Scotland and we make sure the industry meets those.

“That’s unequivocally our focus.

“Across the last 16 months we’ve done more science, more analysis and more listening than ever before.

“Whilst we’re seeing innovation in the sector, we’ve concluded that Scottish salmon farm medicine is significantly impacting local marine environments which increases the weight of scientific evidence that the existing approaches do not adequately protect marine life.

“This is why we’re announcing firm, evidence-based proposals for a revised regime that will strengthen the regulation of the sector.”

Sepa is launching a seven-week consultation on the proposals and will host a series of nine events across Scotland during November and December.

Julie Hesketh-Laird, chief executive of the Scottish Salmon Producers Organisation, said: “This is a rigorous report setting out the modern regulation the industry needs enabling it to grow sustainably over the long term.

“It is the culmination of years of collaborative work between the Scottish salmon farmers and Sepa to develop a new framework for the gradual and careful expansion of the Scottish salmon sector.

“We share Sepa’s vision of an innovative, sustainable salmon industry underpinned by clear and accurate regulation.

“This report will remove many of the barriers preventing the development of more modern facilities further from the shore and we look forward to Sepa’s support as the industry makes this change. ”

SSPO comments on the launch of SEPA’s Finfish Aquaculture Sector Plan and revised regulatory regime

Published on 7th November 2018

The Scottish Salmon Producers’ Organisation (SSPO) has welcomed the launch of SEPA’s Finfish Aquaculture Sector Plan and revised regulatory regime, describing it as “rigorous” but “enabling”.

Julie Hesketh-Laird, SSPO chief executive, said:

“This is a rigorous report setting out modern regulation and enabling the industry to grow sustainably over the long term. It is the culmination of years of collaborative work between the Scottish salmon farmers and SEPA to develop a new framework for the gradual and careful expansion of the Scottish salmon sector.

“We share SEPA’s vision of an innovative, sustainable salmon industry underpinned by clear and accurate regulation. This report will remove many of the barriers preventing the development of more modern facilities further from the shore and we look forward to SEPA’s support as the industry makes this change.

“The various recommendations in the SEPA plan indicate how important up-to-date science is for both the development of salmon farming and its monitoring and regulation. New technology, better science and modelling and a dedicated resource to work with salmon farmers will help to ensure a robust and well-regulated industry with a strong environmental performance record and recognised provenance.

“We welcome the launch of the new model which will be used to understand the potential environmental footprint of our farms. The model will move away from current limitations and help regulate farm activity in a more modern and accurate way. The new regulatory framework supports the development of larger farms and may mean that some farms are best moved to more appropriate locations.

“SSPO has been helping to lead the research work to develop and support the new model and we have embarked on the next phase of the model’s development (project called EXPAND). Ensuring that models are maintained and developed continuously is vital for long-term benefit and, as is the case in other sectors, the industry will undertake the financing of that work.

“The research into the impacts of marine cage farming is an important study and we welcome SEPA’s decision to refer their findings to the UK Technical Advisory Group to make recommendations on new environmental standards for one of the medicines used in salmon farming (emamectin benzoate).

“The discovery of residues is important information but it should be remembered that salmon farmers were operating to SEPA guidelines throughout the past five years.

“The management of sea lice on farms has moved on considerably from reliance on veterinary medicines. The use of cleanerfish – like wrasse and lumpfish – which swim with the salmon to keep them clear of lice is highly effective. Other techniques using warm or fresh water are also working well. In fact, the levels of sea lice on farms is as low now as it has been for the past five years.

“However, salmon farmers need the reassurance that veterinary medicines are available should the need arise and we will be keen to study the recommendations from the UK Technical Advisory Group.

“The industry shares SEPA’s ambition to make Scottish salmon farming a world-leader in innovation and environmental protection. With the new, more accurate and responsive modelling the industry’s compliance rates will improve.”

“We look forward to contributing the consultation.”

SEPA CEO, Terry A’Hearn, introduces proposals for a revised regulatory regime.

The draft plan outlines enhanced standards for organic waste and a strengthened approach for licensing medicines. The plan also details strengthened monitoring and assessment processes and a more comprehensive approach to ensuring fish farm operators comply with all these requirements.

 Finfish Aquaculture Sector Plan

We have also published the following documents which provide additional context to support our regulation of the Finfish Aquaculture sector:

Our press release explains more about the proposals for a revised regulatory regime.

Why We Are Consulting

In preparing this draft sector plan, we have undertaken more scientific analysis, done more thorough thinking and held more discussions with stakeholders than ever before. We are determined to set the best and most up-to-date framework for regulating this sector.

Recognising the diverse range of views on finfish aquaculture, we are keen to hear directly from individuals, interest groups, NGOs, communities, companies and others with a view on the regulatory proposals.

Across November and December we will gather feedback to shape the future of how we regulate the finfish aquaculture sector. We want our communities to inform and enrich the decisions we take every day to protect and enhance Scotland’s environment.

Community drop in events will give you the chance to speak with a range of SEPA staff, find out more about the proposals and answer your questions. No booking required.
