Over 21,000 salmon have escaped from a fish farm in Loch Snizort.
Grieg Seafoods, operators of the fishfarm, said damage to one of the pens was discovered by a diver during a routine check.
Grant Cumming, managing director of Grieg Seafood Shetland Ltd., said: “Our priority is to prevent escape and a temporary mend to secure net was immediately applied.
“Marine Scotland were informed of the incident and the net was repaired the same day. Since then we have counted the fish in the net and regrettably estimate that we have lost 21,700 fish. The fish were in good health and had not received any medicines lately.
“We are conducting an in-depth investigation to discover the root cause of the breach in the net to ensure it does not reoccur.”
