Marks & Spencer has announced it is possible to save the threatened North Sea cod by catching only haddock, according to a report in today’s Telegraph.

The company has said it is possible to set nets at a higher level than when fishing for all bottom level fish it is possible to catch 95% haddock in the nets with only a small percentage of cod.

The trials for M&S were carried out because it has an ethical sourcing policy, whereby is cannot sell North Sea cod because scientific advice says cod levels are below the levels needed for population survival.

Haddock, in comparison, is seeing its highest levels of stock than for the last 20 years, with a population estimated at 460,000 tons.
