Temperature and timing key to effective vaccination using ALPHA JECT LiVac® SRS
Temperature in the first days after vaccination is critical in ensuring that a live attenuated vaccine is effective against salmonid rickettsial septicemia (SRS), one of the main disease challenges in Chilean salmon aquaculture.

Norwegian 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.
Understanding plankton threats to salmon requires a mix of old and new technologies
Using both “traditional” microscopy and environmental DNA (eDNA) analysis can help paint a complete picture of plankton threats to salmon aquaculture, according to University of Glasgow research.
Simulation offers insight into emerging-disease spread on salmonid farms
A new computer simulation approach may help better understand how emerging diseases could spread across salmonid farms in England and Wales and the best measures to limit their impact.
Scientists delve into rising incidence of mycobacteriosis on Norwegian salmon farms
Cases of mycobacteriosis, a serious disease affecting Atlantic salmon predominantly related to Mycobacterium salmoniphilum infections, appear to be on the increase in Norway.
Cage modifications can help manage sea lice problems — but care needed
Sea lice are one of the primary problems affecting Atlantic salmon farming, with severe infestations impacting fish health and performance, and the stress of treatments being linked with the development of other diseases. Changes to the sea cages that salmon are often farmed in offers one solution, according to an expert.
Novel 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.
Vaccine study offers new insight on Norway’s winter ulcer problem
In recent years, the Norwegian aquaculture industry has struggled against the rise of “variant” forms of Moritella viscosa, a bacterium which causes the disease winter ulcer in Atlantic salmon. This has led to concerns about the efficacy of existing vaccines against the pathogen.
