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.
A complex genetic picture is posing problems for Norwegian salmon farmers managing stocks affected by winter ulcer.
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.
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.
Currently, almost all Atlantic salmon producers affected by caligidosis have incorporated Alpha Flux as a useful and effective tool in their parasite-control strategy.
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.
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.
New research shows that thermal and mechanical delousing techniques used in Atlantic salmon aquaculture can cause damage to gill tissue, though the health impacts of this on farmed fish remain unknown.
