Salmon prices are on the rise due to the slump in sterling after the Brexit vote.
Smoked salmon prices rose 24 per cent year-on-year in the 12 months ending 26 March, according to research by Kantar Worldpanel.
Prices on natural salmon in UK supermarkets have jumped 23 per cent.
Currency movements are not the only factor pushing up salmon prices; last year, there weren't enough fish in the sea, driving down yields.
Kantar Worldpanel’s Nathan Ward said: "In terms of fish overall, a lot is bought in euros so changes in the exchange rate have caused prices to rise.
“I can’t see [prices] continuing going up if it is to do with currency change and yield, but I don’t know whether the full effect of those have been passed through.”
