The future of sea louse control on salmon farms: do genetic technologies hold the key?

Salmonids

Norway-salmonid-genome

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.

Learnings from salmon disease outbreaks among Chilean shared-water fish farms

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.

How to bring the pen to the tank

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.

Gill infections - salmon

Tracking salmon through production offers new insight into gill disease

Gills coinfected with three or more pathogens is the “norm” in Western Norway’s salmon aquaculture, new field data suggests — but Neoparamoeba perurans is that which appears to be predominantly linked with gill disease.

New system to assess gill disease could help salmon producers

Gill disease in Atlantic salmon is caused by a number of pathogens and has different clinical and pathological signs. This means that to date, there has been no standardized methodology developed for field diagnosis, despite the fact that gill health issues are a growing concern for salmon producers in all the major salmon-producing nations.
