A team of scientists investigating the potential of a pioneering vaccination against sea lice has secured funding to take its research to the next stage, helping to address one of the aquaculture sector’s ongoing challenges. The global cost of protecting, managing and treating salmon affected by sea lice is estimated at up to $1 billion per year.

“Around the world, different groups including both academics and pharmaceutical companies are now looking at the potential for sea lice vaccines with results beginning to emerge,” said Dr. Sean Monaghan, lead researcher and lecturer at the University of Stirling’s Institute of Aquaculture. “Sea lice vaccination is just one option, but it has the potential to transform the way the sector deals with one of its biggest ecological concerns.”

The Sustainable Aquaculture Innovation Centre (SAIC) has awarded almost £50,000 (U.S. $63,135) to partners from the University of Stirling’s Institute of Aquaculture, AQUATRECK Animal Health SL and Moredun Scientific after a successful initial proof-of-concept phase last year.

“After a highly promising first stage, it is great to see this research progressing because of a successful collaboration between sector experts and researchers,” said Heather Jones, CEO of SAIC. “An alternative treatment for sea lice would have significant, positive outcomes for fish health and welfare, which is a priority area for SAIC. Projects like this, which demonstrate innovation in finfish health, are crucial to creating a more environmentally friendly and economically impactful future for the sector.”

Scientists are developing a new ‘groundbreaking’ oral vaccine for sea lice in farmed Atlantic salmon

In the next part of the study, the team will assess how well the novel vaccine technology works against adult sea lice. It builds on earlier research that looked at the larval stages and discovered a gut protein that helps protect against sea lice. The team is using advanced recombinant expression technology for injection vaccination, which could eventually be produced in large quantities and added to salmon food as an oral vaccine.

The formula has been specially developed to trigger an immune response and create elevated antibody levels in the bloodstream of fish, helping to impair sea lice development and reproductive capacity following sea lice feeding on the fish. By targeting mature lice, the vaccine could also reduce the number of parasite offspring.

Scaling up the technology involved in vaccine development is costly and complex, often acting as a bottleneck for commercialization in any sector. However, during the first phase, the researchers successfully identified a promising route to market by using yeast expression technology to create the recombinant proteins needed for the vaccine at scale.

“Finding a vaccine-based solution for treating sea lice would be a huge development for the aquaculture sector globally, with widespread impact for fish, farmers, the supply chain and consumers,” said Monaghan. “We are hoping that this second stage of the project will demonstrate the efficacy of the vaccine for protecting Atlantic salmon against adult lice and help to build the scientific evidence base.”
