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 MoreUnderstanding 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.
Read MoreManaging health risks in Mediterranean aquaculture’s least-controllable environment
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.
Read MoreSimulation 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.
Read MoreVaccine 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.

Read MoreRace to control bacterial disease which threatens Irish salmon production
The bacterium Piscirickettsia salmonis, which causes the disease salmonid rickettsial septicemia (SRS) in Atlantic salmon, is becoming an increasing concern on fish farms in Ireland.
Read MoreThe future of sea louse control on salmon farms: do genetic technologies hold the key?
Genetic technologies could give salmon farmers the crucial tools they need to prevent sea louse infestations, according to researchers.
Read MoreResearch highlights ways to improve the lives of cleaner-fish species
The welfare of lumpfish used in biological control of sea lice significantly worsens after they are moved to cages at sea, while for wrasse, challenges in nurseries are causing problems before sea transfer.
