The cost of seafood is set to rise after British fishermen warned that soaring fuel prices could force them to tie up their trawlers.
The Telegraph says the Ukraine war sent the cost of the "red" diesel they use up from about 74p a litre at the start of February to as much as 151p, before dipping to just under 100p this month.
The jump has left fishermen struggling to cover their costs, with some resorting to leaving their vessels in port or sending them for maintenance early in the hope that the crisis will soon pass, according to the Scottish Fishermen's Association.
Elspeth Macdonald, the association's chief executive, said prawn, scallop and white fish vessels appeared to be the worst hit and that she had heard "anecdotally" that some were choosing not to go out because of concerns about profitability.
Andrew Selley, chief executive of food wholesaler Bidcorp UK, said the Ukraine war had also caused shortages of fish.
"Russia's the major provider of white fish globally so that's why I think it's been mooted about the increases in staples like fish and chips, because we are seeing big increases - chips as well - in energy and shipping costs," he told BBC Radio 4's Today programme.
It comes as food industry executives warned that surging costs will inevitably be passed on to consumers after official figures revealed that food prices are rising at the fastest pace in more than a decade.
One Kent fisherman became so frustrated with the rising cost of red diesel last month that he hauled his boat ashore and transported it to a petrol station on the back of a lorry, so he could fill up with "white" diesel.
Chris Attenborough claimed he was able to make savings of up to 70p a litre by doing so, once he reclaims road duty and VAT, instead of waiting for deliveries of red diesel to Whitstable harbour.
