The future of sea louse control on salmon farms: do genetic technologies hold the key?
Genetic technologies could give salmon farmers the crucial tools they need to prevent sea louse infestations, according to researchers.
Read MoreResearch highlights ways to improve the lives of cleaner-fish species
The welfare of lumpfish used in biological control of sea lice significantly worsens after they are moved to cages at sea, while for wrasse, challenges in nurseries are causing problems before sea transfer.
Read MoreRevealing shared welfare challenges and solutions in the Scottish salmon industry
Sea lice, gill health and environmental challenges are the major considerations for Scottish salmon producers looking to improve the welfare of their fish, according to an Institute of Aquaculture survey.
Read MoreDistinct 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.
Read MoreNovel 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.
Read MoreHow 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.
Read MoreTracking 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.
Read MoreUser-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.
Read MoreNew 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.
