The Sustainable Food Trust publishes a report today exploring regenerative farming and what impact this might have on self-sufficient food production in the UK. This year was one of the worst avian flu outbreaks for poultry and the disease is also hitting sea birds. Hundreds of bird carcasses have been found across Scotland, with more being discovered in North East England, which the RSPB believes could be linked. And all this week on Farming Today, we're looking at the salmon industry - from wild populations to salmon farming - and today we hear about the dangers faced by migrating wild salmon which travel from river to sea and back again. Presented by Anna Hill and produced for BBC Audio by Caitlin Hobbs
