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.
Environmental DNA testing could provide early warning of barramundi disease
Sampling DNA from the aquaculture environment could aid early diagnosis of scale drop disease, an emerging and potentially severe viral condition affecting farmed barramundi in Asia.
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.

Stomach-resistant oral vaccines could offer fish farmers easier vaccine administration
Oral vaccines hold a great deal of promise for fish farmers. Easier and quicker to administer than injected vaccines, they are also potentially suitable for fish that are too small for injection vaccination, including larval stages.

Combining technology and knowledge to improve aquaculture in Southeast Asia
Southeast Asia is one of the world’s fastest-growing regions for aquaculture, but production efficiency, environmental impact and disease remain bottlenecks for sustainable production.
Molecular testing sheds new light on troublesome microorganism which threatens fish
A new molecular approach has revealed the ubiquitous and opportunistic nature of Saprolegnia parasitica, a fungal-like microorganism that can cause significant disease and economic loss.
