PLAID Cymru Ynys Môn candidate John Rowlands launched the party’s agricultural manifesto in Llangefni earlier this week.
Welsh Government Shadow Minister for Sustainable Communities, Energy and Food, Anglesey AM Rhun ap Iorwerth, Arfon MP Hywel Williams and a number of Plaid councillors joined Mr Rowlands for the event at The Bull Hotel, Llangefni on Tuesday.
Mr Rowlands said: “The family farm is the cornerstone of Welsh agriculture. Here on Anglesey and throughout Wales, the industry represents generations of hard work and makes a vital contribution to our communities and local economies.
"Common Agricultural Policy reform and volatile markets are making business conditions difficult.
“The latest proposals for subsidy payments in Wales will bring considerable challenges to many parts of the industry.
“Plaid Cymru will work to make sure CAP works for Welsh farmers and that all farmers receive their Basic Payments as early as possible within the payment window from 1st December 2015.
"We want to see more public bodies procuring food and drink sourcing more of their products locally in order to support Welsh farmers and local jobs."
Party leader Leanne Wood was also in Bangor to lend her backing to Arfon election candidate Hywel Williams.
A group of the party’s councillors joined Mr Williams and Ms Wood to canvas shoppers on the high street, before taking to the streets to speak to the city’s residents.
