Fish 'n' Chips. Where would the British seaside be without this iconic meal? Fish is one of the UK's favourite foods and the benefits of eating it regularly are widely reported. From sardines to smoked salmon to scampi, fish takes pride of place on Britain's menus and still rates as one of the UK's favourite dishes. Yet with diminishing fish stocks, there's a crisis at sea. So what's a fish lover to do?

Hugh Fearnley-Whittingstall begins an investigative culinary journey around the British Isles to tackle this in River Cottage: Gone Fishing! Hoping to discover alternative, delicious and sustainable seafood that fishmongers should be selling and we should be eating, Hugh's fish fact-finding foray begins in the Channel Islands then takes him all over the British Isles before ending up back in his beloved South West.

Armed with rod, line and an adventurous palate, and with plenty of help from local fish fanciers, Hugh discovers a vast array of underrated seafood and some great ways of making it taste fantastic.
