The National Federation of Fish Friers has warned that cod supplies have increased in price by 75% since October.
Meanwhile fish and chip shops have also seen an 81% increase in the cost of haddock in the last year, a 120% rise in the cost of mushy peas and a 40% surge in the cost of batter.
The NFFF is also urging the UK Government to reconsider its plan to increase VAT on food and soft drinks back from 12.5% to 20% in April which it said is an added concern for the industry.
However, while prices continue to rise in Wigan there are plenty of chippies where you can enjoy a chippy tea for well under £10.
These are 7 of the best chippies in Wigan - according to Google reviews - with fish and chips for under £7.
All of these chippies have a rating of 4.5 or higher out of 5.
