Salmon freeze to death on fish farm
Thousands of salmon have frozen to death on a fish farm on the North Antrim coast.
Staff at a Government fish research centre at Bushmills are battling to save stocks in the sub-zero temperatures - but many have died in water which iced over.
They fear angling in the area could also be hit.
Manager Martin McAleese said: "Every morning we are smashing ice and unless you keep the water running in the tanks overnight, they'll run out of oxygen. The fish suffocate."
He told BBC Radio Ulster: "These fish are vital, not only for angling, but for the research which has been going on for almost 40 years. If they don't survive, then that's a big gap in the research."
