Maison Morisseau

What Maison Morisseau does

Maison Morisseau is a privately held, family-owned French mussel farming and distribution company headquartered in Le Vivier-sur-Mer, with operations in La Plaine-sur-Mer (Jade Coast) and a retail/showroom presence in Dinard through its L'Atelier Morisseau® subsidiary. The company cultivates bouchot mussels using wooden stakes driven into the sea floor and natural coconut fiber ropes for spat collection, with on-land seawater basins used for purification before sorting and packaging. It operates six distinct product lines (La Morisseau®, La Bouchot de l'Équipage®, La Bouchot Sélection, AOP Mont-Saint-Michel Bay, L'Entre 2 Saisons) collectively spanning May–February availability, including a PDO-certified line governed by a structural charter that has fixed the number of bouchot stakes for over 40 years.

The company sells primarily through B2B channels — direct to fishmongers, wholesalers, restaurateurs, GMS (mass retail), and collective catering — supplemented by seasonal direct-to-consumer retail counters (Le Comptoir de l'Équipage, L'Épicerie De La Mer) and a tasting room at L'Atelier Morisseau in Dinard. Pricing is not publicly disclosed and is conducted on a per-order quote basis across B2B, with one-time purchases at the D2C counters. The business has invested in producer partnerships (e.g., Famille Dupuy) to extend seasonal supply, and has received multi-year EU and regional grants (FEAMPA, Région Bretagne, Région Pays de la Loire) for production facility construction (2023), automated grading equipment (2024), and washing/packaging modernization (2025).

The company is led by a small team (approximately 15 employees) anchored by a three-generation heritage of mussel cultivation, with Stéphane Vignau in commercial leadership, Steve Biheuc as Director of Production at La Plaine-sur-Mer, and Olivier Daniel serving as data controller. Maison Morisseau holds the Positive Company® 2-star RSE label (2024) and operates a content-marketing presence across LinkedIn, Instagram, and Facebook under multiple brand handles. No public financial data is disclosed; revenue is private, and the legal entity is registered in France.
