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.
Read MoreNew tools can transform understanding of aquaculture’s microbiology
The microbiome of aquaculture systems has long been known to have a significant role in fish health and welfare issues, yet a full understanding of these interactions has often eluded experts.

Fish farmers’ efforts to protect the environment often come at a cost to fish welfare, say scientists at the University of Melbourne, in a new opinion paper.
Read MoreNew knowledge could aid diagnosis of salmon farms’ troublesome cardiac disease
Screening plasma and kidney samples could prove a useful method to provide early diagnosis of cardiomyopathy syndrome (CMS), a common viral disease which causes mortality and welfare issues in Atlantic salmon farming.

New, affordable technologies are changing the speed and cost at which full-genome sequences can be produced for diverse applications.
Read MoreColumnaris disease affects Nile tilapia eggs and larvae, study suggests
Columnaris disease, a potentially devastating condition affecting freshwater finfish, has been found infecting Nile tilapia eggs and larvae for the first time.
Read MoreUnderstanding, but not application, of sustainable health measures in Vietnam’s pangasius industry
Pangasius farmers in Vietnam generally view vaccination in a positive light and are concerned about antibiotic use, although further work is required to ensure sustainable practices are widely implemented, new research led by University of Stirling suggests.
Read MoreStudy tracks salmonid alphavirus transmission in Norwegian aquaculture
New genomic analysis of salmonid alphavirus subtype 2 (SAV2) samples from Norway has shed new light on how the pathogen has spread through the country since its introduction in 2010.
Read MoreHow to bring the pen to the tank — without compromising fish disease-research strength
In-tank studies remain the bedrock of research into aquaculture disease, but their design is changing to meet demands to replicate scenarios closer to field conditions, according to Mark Braceland, PhD, director of fish health at the Center for Aquaculture Technologies.
Read MoreTilapia strain resistant to damaging virus could help reduce losses
The discovery of a strain of Nile tilapia resistant to tilapia lake virus (TiLV) may prove useful in the fight to reduce the impact of the pathogen, which has emerged in the last decade and can cause extremely high mortalities among farmed fish.
