Fishing is one of the most popular outdoor pursuits in the UK, with three million anglers casting their lines each year. The UK’s coastlines and rivers offer incredible fishing opportunities, from bass swimming in our seas to trout meandering through our rivers. Some fish, however, are trickier to catch than others.

Joe Crowley visits the Dorset coast to team up with a local fly fisherman as he takes on one of the UK’s most difficult fish to catch – the mullet. Joe learns about a very specific method, using unique flies created to hopefully entice one in. Along the way, we trawl the Countryfile archives in search of stories about our relationship with the fish that call our rivers and seas home.
