Caz Graham hears five of the eight species of tuna could be at risk from extinction. The International Union for Conservation of Nature is calling for urgent action to prevent over fishing. Although Bluefin tuna - the species most at risk - are rarely eaten in the UK, Albecore and Yellowfin tuna are eaten both tinned and fresh. Farming Today hears the numbers of both have decreased dramatically.

New government statistics show the average cost of feeding cattle, pigs and poultry outstripped inflation in the first quarter of this year, and some pig farmers have seen feed prices double in the last 12 months. A visit to a prize-winning pig breeder shows the challenges faced in balancing the books.

And Caz Graham visits one of a dwindling number of vegetable growers in Cumbria. Production in the county dropped by 22 percent between 2009 and 2010 and the small-scale producer is becoming something of a rare breed. James Walton in Dalston is one of the survivors.
