How to balance fish welfare and environmental protection in aquaculture
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.
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.
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.
Novel parasiticide part of quest for long-lasting sea lice control in Chile
Currently, almost all Atlantic salmon producers affected by caligidosis have incorporated Alpha Flux as a useful and effective tool in their parasite-control strategy.
