Mowi Scotland Achieves Significant Improvements in Fish Health and Biology in 2024
Mowi Scotland had a remarkable year in 2024, showcasing substantial enhancements in salmon health, welfare, and overall performance. The collective efforts of the Mowi Scotland farming teams resulted in a 35% reduction in overall biomass mortality across all seawater farms compared to the previous year, with a staggering 45% reduction when mortality is expressed in terms of individual fish numbers.
Driving Factors Behind the Success
Key to this improvement was the relentless work of both the Health and Production teams in addressing health challenges and mitigating environmental stressors. Strategies were refined, biosecurity was enhanced, and innovative solutions were implemented, all while placing a strong emphasis on prevention. Favorable climate conditions in 2024, including slightly cooler temperatures and abundant rainfall in the summer, also played a role in the success.
Vaccination Advancements
Mowi Scotland has been rapidly advancing in preventive health strategies, introducing one new vaccine per year since 2022. These autogenous vaccines, developed in collaboration with Ridgeway Biologicals, have significantly contributed to the improved biological outcomes observed in 2024. The company continues to explore new solutions to safeguard their fish, particularly against emergent pathogens like Piscirickettsia salmonis.
Biosecurity Measures
Biosecurity remains a critical aspect of Mowi’s operations, from egg to harvest. The company employs the latest technologies for water filtration, parasite control, and disinfection to ensure pathogen-free operations. Additionally, developments in bacteriophage therapy show promise in revolutionizing biosecurity measures and reducing the use of antibiotics in farming.
Parasite Control and Pest Management
Significant improvements in pest control for sea lice and Amoebic Gill Disease were achieved in 2024, contributing to reduced mortality rates. Non-medicinal solutions, cleaner fish, and innovative technologies like bubble curtains were instrumental in controlling pests and safeguarding salmon health.
Addressing Challenges with Jellyfish
Mowi Scotland has been proactive in mitigating the impacts of harmful plankton species and jellyfish in Scottish waters. Innovative measures such as feed withdrawal and the use of aeration systems have proven successful in protecting salmon stocks. New technologies like bubble curtains have shown promise in combating jellyfish infestations.
Strategic Developments for Enhanced Performance
Mowi Scotland launched a new breeding programme and a post-smolt strategy in 2024 to strengthen salmon farming in Scotland. These initiatives aim to produce more robust stocks and reduce exposure to health risks, ultimately improving fish health and performance.
Continued Commitment to Research and Innovation
Looking ahead, Mowi Scotland has embarked on a new five-year project with the University of Edinburgh to further build scientific knowledge and develop new tools and innovations for sustainable salmon farming. The company’s dedication to research and talent development underscores their commitment to sustainability, welfare, and performance.
Appreciation for the Mowi Scotland Team
The success of 2024 would not have been possible without the dedication and skills of the Mowi Scotland team. Special recognition is extended to the Health and Production teams for their exceptional work in safeguarding the welfare and health of the salmon across all operations.
