Small-scale fishermen believe they could face prosecution because of an App which has been launched to monitor their catches, which they say doesn’t work for them. From the end of February, English vessels of under 10m have been obliged to use the Catch App - designed by the Marine Management Organisation - to record what species and how much they catch, and where they land it. Failure to do so accurately could lead to an unlimited fine. A group of fishermen from around England - under the campaign name "Scrap the App" - have now applied for permission for a judicial review, to get the MMO to delay enforcing the new regulations. Irish farmers are being asked by their Government to plant more cereals, as part of emergency plans to offset a predicted food security crisis because of the invasion of Ukraine. Between them, Russia and Ukraine account for 30% of global wheat exports. We asked DEFRA if we could expect a similar move here - it told us it’s in regular contact with major grain traders, manufacturers and food retailers … and it doesn't expect to see any significant direct impact on UK food supply. And as part of a week long focus on the impact of the Northern Ireland Protocol on food and farming, we hear from one company that has benefited from an increase in exports to the Republic of Ireland.
