In October 2007, Nissui acquired 59% of the issued shares of Cité Marine, a French producer of processed seafood from the founding family and the firm thereby became a member of the Nissui Group. In order for Nissui, which has developed a distribution network for marine products in Europe, to further expand its business, it was a prerequisite to obtain a producer that can "create greater customer-oriented value from marine resources."
Cité Marine was founded in 1990 with its head office based in Kervignac in the Bretagne region in the northwest part of France. Its main plant is on the premises of its head office and it also has another plant, the Malabry plant, in Prenessaye, which is located 80 km to the east. The main plant mostly produces fried and ready meal products (frozen and chilled foods) through six production lines, while the Malabry plant produces natural and frozen fried skewered products in four production lines.
