Some salmon producers may keep their cages fully submerged to keep sea lice at bay, but results from a recent trial suggest that while this reduces lice infestations, it is detrimental to salmon welfare and production go…

A Scottish startup has received £125,000 from the Seafood Innovation Fund (SIF) to explore the benefits of using natural kelp structures as hides for cleaner fish on salmon farms.

Emerging research shows that keeping rainbow trout under constant light disrupts their body clocks and could leave them more susceptible to parasites.

Field trials with Mowi Chile demonstrate that lice skirts made with Garware fibres can successfully contain infestations of Caligus larvae while allowing water to flow and maintain dissolved oxygen levels during…
