Land-based salmon producer Pure Salmon is relocating its planned French production site away from the northern port city of Boulogne-Sur-Mer to a new site in southwestern France.

The company made the surprise move because it is unable to gain access to salt water used in the plant's operation.

Landacres Pure Salmon's original choice for the farm, is less than a 20 minute drive from Boulogne-sur-Mer, while the new site in Gironde, France, is around eight hours away.

Last year, Pure Salmon acquired the recirculating aquaculture division (RAS) of Kruger Kaldnes, now known as Pure Salmon Kaldnes under a plan to use brackish and salt water in the production process.
