One pathogen strain seems the main culprit in damaging salmonid disease
A distinct strain of the main fungus-like pathogen which causes saprolegniosis — thought to be responsible for around 10% of economic losses in the salmonid industry — looks likely to be responsible for the majority of outbreaks of the disease on Atlantic salmon fish farms.

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.
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.
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.
Taking farmed fish welfare beyond the ‘five freedoms’
Over the last decade, a considerable body of research has demonstrated the capacity of fish to suffer – yet there remain unknowns around what causes the most serious negative impacts on their quality of life.
Tilapia 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.
Biosecurity’s crucial role in ensuring sustainable future for global aquaculture
An interview with Vera Agostini, deputy director, Fisheries and Aquaculture Division, the Food and Agriculture Organization (FAO) of the United Nations.
Levels of antimicrobial resistance in Asian aquaculture ‘concerning,’ say scientists
Twenty years’ worth of data “raise urgent concerns” about antimicrobial resistance in Asian aquaculture, say the authors of a new review.
Prioritizing biosecurity can help tame tilapia lake virus
Tilapia lake virus (TiLV) is an emerging threat to tilapia aquaculture, with mortalities in some cases up to 90%. But with a focus on biosecurity, the impact can be considerably lessened.
