Neeltje Jans Mosselen

What Neeltje Jans Mosselen does

Neeltje Jans Mosselen is a family-owned shellfish farming, processing, and supply company headquartered in Vrouwenpolder, Zeeland, Netherlands, on the former Neeltje Jans work island adjacent to the Oosterschelde storm surge barrier. Founded in 1912 by the Schot family, the company cultivates Zeeland mussels using two methods: hangcultuur (rope-grown mussels in former Delta Works construction docks, protected from heavy waves but with excellent water circulation, available May through December) and bodemcultuur (bottom-grown mussels with 110+ years of expertise, available July through February). The product portfolio has been expanded to include cultivated oysters (launched in 2019 on tables in the Schelphoek area of the northern Oosterschelde), Oosterschelde lobster (fished since 1919, with a significant market share acquired through Sam Uyl's license in 2019), and an extensive assortment of other shellfish, as well as imported French oysters from Normandy and European/Canadian lobster for year-round supply.

The company operates a vertically integrated model: harvesting is conducted with three owned vessels (ZZ4, ZZ9, ZZ18), processing happens at an on-site facility with an advanced packaging line handling formats from 1 kg vacuum packs to 15 kg jute bags, and distribution is executed through multiple channels. These include two retail storefronts (Proef Zeeland in Vrouwenpolder and 't Mosselpakhuys in Zierikzee) operating under the Proef Zeeland partnership, wholesale supply to restaurants, fishmongers, and supermarkets, and an owned delivery fleet serving customers across the Netherlands, Belgium, and occasionally France. Customer segments span individual consumers, the hospitality sector, and supermarket/fish specialist retail.

Revenue is generated through one-time transactional sales of fresh and processed shellfish, with no subscription or recurring pricing model. Pricing is not publicly disclosed; customers are directed to contact the sales team for quotes. The company holds four notable certifications: MSC (Marine Stewardship Council) for sustainable fisheries, Zeker Zeeuws for guaranteed Oosterschelde and/or Waddenzee origin, IFS Food (valid 2026-2027) for food safety, and NL-BIO-01 organic certification (2025).
