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.
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.
The consolidation of Mediterranean aquaculture is standardizing production practices in the region and leading to better biosecurity management, but growing out fish in the unforgiving environment at sea poses the sort of challenge that demands realistic, practical solutions.
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.
Cases of mycobacteriosis, a serious disease affecting Atlantic salmon predominantly related to Mycobacterium salmoniphilum infections, appear to be on the increase in Norway.
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.
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.
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.
