Countryfile is in the east Midlands to find out about the region's rural past and the revival of the River Trent. Matt Baker takes to the Trent in a kayak and meets Alan Henshaw from the environment agency who tells him about the effort to clean up the river. Matt sees for himself the improvements in water quality and habitat, before taking a trip to Calverton Fish Farm in Nottinghamshire.

Alan puts its prize-winning taste down to the rare breed red poll cattle, a once common breed in the region.
