In total, 268 publicly supported projects worth more than £183m have been delivered since 2018 by salmon producers, supply chain businesses, universities, and public funders working in partnership.

The figure excludes projects funded entirely by companies, meaning overall spending on new technology is likely to be significantly higher.

The review, conducted by research consultancy Frontline and commissioned by the Sustainable Aquaculture Innovation Centre (SAIC) and trade body Salmon Scotland, concludes that innovation has broadened across every major area of salmon farming.

More than £83m has gone into fish health and welfare alone, supporting work on vaccines, diagnostics, welfare tools, and disease prevention.

Significant backing has also been directed towards sea lice management, including biological controls, new treatment technologies, and AI-enabled detection systems.

The findings have been welcomed by the Scottish Government.

Cabinet Secretary for Rural Affairs Mairi Gougeon said: “I welcome this report’s endorsement of the positive impact of long running public investment in aquaculture innovation.

“Scottish salmon aquaculture is a highly agile sector, constantly adapting to the complex marine environment – and it is able to do that because of the focus collectively put on generating world class aquaculture science.

“The changing marine environment continues to present challenges, and Scotland’s track record of innovation indicates the sector will rise to those challenges to ensure the sustainable development of aquaculture into the future.”

Dr Suzanne Hamilton, Frontline director, added: “This study shows how much aquaculture innovation activity has taken place in Scotland since 2018.

“Funding has supported real progress in fish health and welfare, environmental sustainability, and productivity, with research increasingly translating into practical outcomes.

“However, innovation is not instant. The impacts of research and development are often realised over several years as new approaches are tested and adopted.

“While support in recent years has been substantial, the future landscape is less certain, with fewer aquaculture-specific funding calls ahead.

“Continued, targeted investment will be important to maximise the benefits of what has already been achieved.”

Genetics and breeding programmes have advanced in parallel. One of the largest initiatives is the £8.5m Biotechnology and Biological Sciences Research Council (BBSRC) Business and Academia Partnership Prosperity Programme project, Drivers of Salmon Robustness.

Delivered with Mowi Scotland and the University of Edinburgh’s Roslin Institute, the programme aims to breed salmon that are more resilient to farming challenges.

Those involved say the work is already delivering practical results, from new tools to identify high-performing fish to technologies that enhance fish health and welfare, alongside education programmes in regional schools.

Across all the companies interviewed for the review, almost nine in 10 (88%) said employment would have been lower without innovation activity, while three quarters (76%) reported turnover would also have been reduced.

Much of the work has been carried out jointly by salmon producers and Scotland’s universities, spanning faster disease detection, improved breeding strategies, and enhanced environmental monitoring.

The review warns that innovation can still be slowed by short-term funding and lengthy regulatory processes, making it harder to test and adopt new ideas quickly.

It calls for longer-term support and faster routes to trials if momentum is to continue.

Projects highlighted range from real-time alerts for harmful algal blooms to advances in fish health.

Among them is WellFish Tech, a University of the West of Scotland spin-out that provides rapid, AI-driven blood diagnostics, with results returned within 24 hours to help farmers monitor salmon health and welfare.

Faster results mean farmers can respond sooner if there are signs of stress or disease.

The innovation push is set to continue, with a £17m national aquaculture technology hub due to open at the University of Stirling this year.

Dr Iain Berrill, head of technical at Salmon Scotland, said: “This review shows the scale of innovation now under way in salmon farming in Scotland.

“Almost £200m worth of publicly supported projects have been delivered over the past eight years, helping raise standards and strengthen performance across the sector.

“Salmon farmers in Scotland already operate to some of the highest standards in the world, but like any form of food production, we must invest in the latest research and innovation.

“Much of this investment has gone into fish health and welfare, from vaccines and diagnostics to technology that helps detect issues sooner and improve outcomes.

“There has also been significant progress in breeding, environmental monitoring, and tackling sea lice.

“Continuing to innovate will be essential to maintaining standards and building resilience for the future.”

Sarah Riddle, head of research and innovation at SAIC, said: “This report demonstrates the strength and maturity of Scotland’s aquaculture innovation system.

“The volume of activity and the speed at which new ideas are being developed show exceptional collaboration across industry and academia.

“The scale and breadth of activity highlight Scotland’s position as a global leader in aquaculture.

“Crucially, they show that these projects are delivering real‑world impact: better fish health, improved productivity, new technologies, enhanced environmental performance and climate readiness.

“Continued, strategic support for collaboration and innovation is essential to maintain this momentum.

“With the right long‑term investment, infrastructure and regulatory alignment, Scotland is well placed to build on its achievements and enhance the sector’s resilience, competitiveness and sustainability.”
