The modern building, which opened for business in June, is a key part of the £5 1million redevelopment of the historic fishing town’s harbour by the Peterhead Port Authority.
Mr Stevenson attended the opening on Saturday alongside the Duke of Rothesay and the local community.
More than 500 guests from all across the North-East were invited to the market to celebrate its official opening.
The new building is able to hold 10,000 boxes of fish at a time and boast the latest in refrigeration technology which, when combined with better access for boats from the quayside and lorries from the shoreside, allows Peterhead-landed seafood to reach plates fresher than ever.
Commenting, Stewart Stevenson MSP said:
“I was delighted to be present for the official opening and I would like the congratulate Peterhead Port Authority.
“This is a fantastic new facility which has been supported by £5million of funding from the Scottish Government and the European and Maritime Fisheries Fund.
“I would like to thank retiring Chief Executive John Wallace and welcome the new Chief Executive Simon Brebner in his new role.
“This is an important moment in the development of Peterhead Port Authority and I wish them every success going forward.”
