The firm will pay an additional £45 - £1 for each specimen charge
A Cornish fishing firm has been ordered to pay an additional nominal fine of £45 for cheating on fishing quotas.
W Stevenson and Sons received a confiscation order last month for £710,220, but the firm was also given a conditional discharge.
Judge Philip Wassall said the order and discharge could not go together and he was correcting a legal mistake.
The Newlyn fish auctioneers will now pay £45 - £1 for each specimen charge - on top of the £710,220.
The firm was convicted in 2007 of eight charges relating to the illegal landing and sale of quota fish at Newlyn. It pleaded guilty to another 37 charges.
An earlier confiscation hearing heard the firm benefited by more than £4m.
But in making the payment order, a judge at Exeter Crown Court took into account the possible effect a larger amount could have on the local economy.
The firm was also ordered to pay £66,000 costs.
At the trial in 2007, Exeter Crown Court was told that during six months in 2002 almost a quarter of fish landed by a sample of 20 Stevenson vessels was illegal.
Cod, hake and anglerfish were falsely described as non-quota, lower-value species such as ling, turbot and bass.
The Stevenson firm, which runs auctions where the fish are sold, also falsified the auction records to make sure they matched the figures provided by the skippers.
This enabled them to break the European rules designed to save dwindling fish stocks.
The firm is run by Elizabeth Stevenson, former president of the National Federation of Fisheries Organisations.
She said after the case: "We are grateful that the judge recognised our contribution to the local and national fishing industry and the local economy.
"It's not going to be easy to find this sum of money. It's huge, but the case has ended well."
She added: "We haven't got away with it. It's absolute hell to take part in a case like this."
Earlier this year, the owners and skippers of six Newlyn fishing boats were fined for their part in the scam.
