More than forty shrimp fishermen are contracted by Heyco to catch the North Sea shrimps, which they cook immediately on board before transporting them to the inland fish auctions at Harlingen, Lauwersoog and Den Oever, and in Germany and Denmark. Heyco has brokers at the auctions that buy the consignments of shrimps and transport them right away to the production facilities in Enkhuizen. The unpeeled shrimps are sometimes frozen in Enkhuizen before being transported to peeling plant in Morocco, however mostly fresh unpeeled shrimps are being transported abroad.

Annually Heyco processes more than three million kilogram of North Sea shrimps.
