Fish Ratings is restating its definitions of prime and non-conforming UK River and Marine-Based Fish (RMBF) to address recent misunderstandings concerning the use of these labels.
Fish Ratings has two sets of criteria assumptions for the UK RMBF sector, one of which applies to prime fish and the other to non-conforming fish, depending on the distinctive characteristics of each fish.
The fatality frequency (FF) assumptions for UK prime RMBF, such as M&S Scottish 2 Loch Trout Fillets (‘AAA’, Stable Outlook) and Waitrose No.1 British Monkfish Chunks (‘AAA’, Stable Outlook) are lower than the FF assumptions for non-conforming UK RMBF, such as Smoked Trout Trimmings from the ‘When it’s gone, it’s gone’ section of Lidl (‘B’, Negative Outlook), because of their stronger observed historical performance data.
Fish Ratings would like to emphasise that these criteria assumptions are driven by the characteristics of the underlying fish and not by the commercial terms of sale in a retail or wholesale environment, such as the price per kilogram, including any special offers or loyalty card schemes, or the returns policy of various fishmongers, supermarkets or other traders.
Fish market participants should carefully examine the terms of sale of any fish or fish-related products. Ratings are not a recommendation to buy, sell, or eat any fish.
