Large-scale study focuses on fish health and welfare
Mowi is to partner with the Roslin Institute in an £8.5m large-scale study to improve the welfare and productivity of farm-raised salmon in Scotland. In the five-year partnership, together we will seek to understand how to limit the impact of chronic complex diseases, enabling better health and welfare. The project will use a range of
Highlights from Mowi freshwater in 2024
2024 was the biggest year of freshwater production for Mowi Scotland ever. A total of 22.5 million smolts were put to sea at Mowi farms, Wester Ross and some third-party farms. This is a huge logistical challenge with 38 million fish transported by road and 11 million fish delivered to sea from the end of
Significant drop in salmon mortality recorded at Mowi Scotland
Mowi Scotland recorded a significant drop in salmon mortality during August. Mortality was around one third of that recorded in recent years when El Niño conditions caused a marine heat wave in the North Atlantic. El Niño is part of the natural climate phenomenon called the El Niño Southern Oscillation (ENSO) and leads to warmer
Mowi Scotland pioneers new sea lice modelling
Mowi Scotland has pioneered new sea lice modelling as part of its application to grow post smolt salmon at its farm in Loch Etive, which has now been approved. The model will offer the most effective control of sea lice and was developed by Dr Philip Gillibrand, Mowi’s Head of Oceanography and Environmental Monitoring. Dr
Fish farmers prepare for warm summer weather
Just as holidaymakers are packing for a summer outing to Scotland’s warming waters and beautiful sunny beaches, the country’s salmon farmers are preparing their fish farms for the challenges that summer conditions bring. Despite sea temperatures in the UK rising more than a degree over the past decade, Scottish waters still remain optimal for salmon
New fish vaccines developed at Mowi
Building on the success of previous collaborations between Ridgeway Biologicals Ltd and Mowi Scotland that have delivered effective vaccinations to protect fish health, the partnership has now developed a new vaccine strategy to safeguard salmon against the bacteria Yersinia ruckeri. Bacterial infection by the pathogen can lead to a disease known as enteric red mouth
Wellboat review
Since Ocean Matters was founded in 2015, lumpfish have been transported by lorry to salmon sites in Scotland, Ireland and even to the Faroe Islands. The typical load per trip usually allows for between three or four pens to be stocked. By contrast, all Mowi sites in Norway are stocked with cleanerfish via wellboat. The
Gathering for fish health
Fish Health Observer training at Mowi’s land-based recirculating aquaculture system Mowi’s fish health team has recently been bolstered by the recruitment of fish health observers (FHO) throughout all farming locations that oversee fish health and welfare; that includes cleaner fish deployment, welfare monitoring, biosecurity, vaccine auditing and many other important activities along the production cycle.
