The bacterium Moritella viscosa is considered an important causative factor for the disease winter wounds and a common denominator for outbreaks is exposure to low sea temperatures and / or infection in wounds after mechanically inflicted injuries.
Winter sores are most common in the winter months when there are low water temperatures, and cause both mortality and downgrading at slaughter. The disease is therefore both a welfare problem and an economic problem.
In addition to representing a challenge at sea, winter sores have caused problems in land-based production of salmon hatcheries using seawater. In hatcheries with seawater intake, winter sores are often associated with the intake of seawater from slightly deeper and colder water layers.
Extended smolt phase (postsmolt) in land-based or semi-closed fish farms in the sea is considered as an alternative to reduce the time in open nets. However, this places great demands on the intake water to avoid ingestion of disease-causing organisms (pathogens). Experience from hatcheries shows that disinfection with UV does not act as a sufficient barrier for ingestion of the bacterium Moritella viscosa.
Goal to test a hypothesis that membrane filtration of cold seawater infected with Moritella viscosa will retain M. viscosa and that the filtrate will be 100% free of this bacterium.
