Cage 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.


Warming climate could mean more-virulent fish viruses, study suggests

Rising temperatures may increase the risk that viral pathogens pose to farmed seafood species, according to French research.
