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.
Managing 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.

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.
Tackling jellyfish blooms affecting farmed fish in the British Isles
Tiny jellyfish have contributed to cases of gill disease in farmed Atlantic salmon in Scotland and Ireland in the past year, but early recognition and maintaining good general gill health are key to reducing the threat.
Race 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.
The 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.
