Stolt Sea Farm's premium trademarked sole line 'King Sole' is being launched at Auchan supermarkets in France.

The retailer has sold Stolt Sea Farm’s turbot range since 2017.

The fish weighing 500g and above will initially be available in selected Auchan stores from the end of this month with the supermarket chain hoping to expand the supply nationally in the coming months.

"Auchan has been an important customer of ours for some years now and this partnership has been fundamental in supporting our growth in the French market, where our sales have doubled over the past two years," said Stolt Sea Farm President Jordi Trias.
