RSPCA Assured, the nonprofit arm of animal welfare body RSPCA, has temporarily suspended its certification of a farm belonging to Scottish Sea Farms amid an investigation into fish welfare at the site.

Last week, activist group Scottish Salmon Watch published covertly filmed video and images that appear to show fin damage and other wounds on live fish at the Scottish Sea Farms site at Loch Spelve, near Dalnaha on the coast of Mull.

The campaigners say they filmed on the evening of May 7 at two cages.
