The pioneering project is in response to the lessening productivity of natural waters and the growing con- sumer demand for healthy and sustain able fish products. “ Year-round and sustainably produced fish from the region is our goal.” Rüdiger Buddruss, company director of KM Seafood It is precisely in the seafood sector where the seasonal availability and the asso- ciated fluctuations in price and quality often provide a nuisance to consumers and for the institutions involved in sales and marketing.
