New 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.
New 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.
How accessible genome sequencing supports sustainable aquaculture
New, affordable technologies are changing the speed and cost at which full-genome sequences can be produced for diverse applications.
Study 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.
Distinct bacterial variants make winter ulcer diagnostics ever-more important
A complex genetic picture is posing problems for Norwegian salmon farmers managing stocks affected by winter ulcer.
Vaccines and smart sea lice control helping Chilean salmon giant improve sustainability
Salmon rickettsial septicemia and Caligus sea lice are two of the major concerns affecting salmon production in Chile. Thanks to new approaches in fish-health management, Blumar Seafoods is successfully limiting their impact.
Measurement and environment are key to fish welfare
In the last decade, fish welfare has become a prominent driver of aquaculture operations. Angela Ashby, head of clinical services at PHARMAQ Analytiq, believes that the engagement of production staff in this area remains underappreciated.
Disease outbreaks in open aquaculture systems highlight benefits of collaboration
Disease is a shared problem for those farming fish in the open sea, say industry experts — and the results of better collaboration are plain to see.
How 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.
User-friendly tools put cleaner fish welfare in the spotlight
A package of tools designed by scientists at Swansea University has been made available to help producers monitor the welfare of lumpfish, commonly used as biological control for sea lice on salmon farms.
