How to reduce antibiotic use in Chile, the Americas’ salmon-production giant
Cutting antibiotic use is one of the major sustainability priorities in global food production, and while aquaculture has taken steps along this road, there’s still a long way to go.
Read MoreSome functional feeds may have trade-offs for salmon health — new study
There is a complex balance between the benefits and drawbacks of functional feeds for Atlantic salmon when fish are facing concurrent health threats, a Canadian study suggests.
Read MoreResearch highlights risks of thermal delousing treatments for unhealthy salmon
Thermal sea lice treatments do not appear to cause increases in pathogens which threaten farmed salmon, but the risk of stress-related mortalities means that fish already suffering from disease should not undergo thermal sea lice treatments, according to Institute of Aquaculture researchers.

The Norwegian Veterinary Institute’s latest Fish Health Report1 has highlighted record numbers of sea lice treatments and bacterial diseases causing complications for fish producers in Norway — but in order for its authors to keep up with changes in the industry, new, more specific data needs to be collected and made available in coming years.
Read MoreCage modifications can help manage sea lice problems — but care needed
Sea lice are one of the primary problems affecting Atlantic salmon farming, with severe infestations impacting fish health and performance, and the stress of treatments being linked with the development of other diseases. Changes to the sea cages that salmon are often farmed in offers one solution, according to an expert.

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.
