A report on Decapod Crustacean welfare in the UK seafood industry reveals that companies like Marks & Spencer, Waitrose, and Young's Seafood are leading the field, but there are disparities between companies in taking action on decapod crustacean welfare. The report is the first benchmark to assess leading seafood producers, processors, retailers, and wholesalers in the UK on their management practices and reporting of welfare standards for decapod crustaceans. Although there has been significant progress in companies publishing policies on decapod welfare areas, more than half of the companies assessed scored less than 20% and more action is needed on humane stunning and slaughter methods for decapods.
