Research highlights risks of thermal delousing treatments for unhealthy salmon
Thermal sea lice treatments do not appear to cause increases in pathogens which threaten farmed salmon, but the risk of stress-related mortalities means that fish already suffering from disease should not undergo thermal sea lice treatments, according to Institute of Aquaculture researchers.
Read MoreNorwegian salmon industry’s annual ‘health check’ underlines areas for improvement
The Norwegian Veterinary Institute’s latest Fish Health Report1 has highlighted record numbers of sea lice treatments and bacterial diseases causing complications for fish producers in Norway — but in order for its authors to keep up with changes in the industry, new, more specific data needs to be collected and made available in coming years.
Read MoreNovel sampling reveals microbial changes during gill disease on Irish salmon farm
A non-lethal sampling method combined with cutting-edge molecular analysis has shed new light on microbial interactions in Atlantic salmon gills during a gill disease outbreak.
Read MoreExposed, offshore salmon farms may complicate fish-health challenges
Life on exposed offshore aquaculture sites may increase the susceptibility of farmed Atlantic salmon to parasites and pathogens.
Read MoreTracking salmon through production offers new insight into gill disease
Gills coinfected with three or more pathogens is the “norm” in Western Norway’s salmon aquaculture, new field data suggests — but Neoparamoeba perurans is that which appears to be predominantly linked with gill disease.
Read MoreNew system to assess gill disease could help salmon producers
Gill disease in Atlantic salmon is caused by a number of pathogens and has different clinical and pathological signs. This means that to date, there has been no standardized methodology developed for field diagnosis, despite the fact that gill health issues are a growing concern for salmon producers in all the major salmon-producing nations.
