Seafood Scotland wrote to the chief executives of major UK supermarket chains ASDA, Sainsbury’s and Tesco on Wednesday, urging them to reopen their fresh fish counters.

With international markets closed off, and the UK restaurant and catering sector largely shut down, “the entire sector is relying on retail for survival," yet most of the fresh fish counters in major multiple retailers have been closed for weeks, said the group.

Only Morrisons has reopened its fresh counters in recent days, in a move to support the meat and fish sectors.
