Inadequate utilization of available food resources constitutes a major problem regarding the growing population, the increased demand for food and the current need to reduce the global footprint exerted on the planet. Understanding value chains, identifying pressure points and room for improvement using new technological solutions, are important steps to enhance raw material utilization for the individual industries. Marine resources generated from the fish industry is an important part of the Norwegian food production and contributes about 4% to mainland gross domestic product. The most important industries are Atlantic salmon (Salmo salar) aquaculture, and wild capture of pelagic fish, cod (Gadus morhua) and saithe (Pollachius virens). Processing to saleable products, mainly fillets, generates large amounts of marine rest raw material. Logistics of aquaculture production and processing allow for close to 100% utilization, while only 44% of the white fish rest raw material is being utilized. Farming of fish close to shore enable processing of rest raw material immediately after slaughter, which is paramount to avoid deterioration. Cod and Saithe are mainly caught at sea by sea trawlers and the coastal fleet, with on-board handling and transportation to shore being hurdles to overcome for processing of rest raw material to high quality products for human consumption and animal feed. This review will focus on the value chain of the white fish industry in Norway, its history, current status and possibilities of improvement to better utilize rest raw material.

有关可用粮食资源的利用不足构成了一个主要问题，涉及人口增长，对粮食的需求增加以及当前减少对地球施加的全球足迹的需求。了解价值链，使用新技术解决方案确定压力点和改进空间，是提高各个行业原材料利用率的重要步骤。鱼类产业产生的海洋资源是挪威粮食生产的重要组成部分，约占大陆国内生产总值的4％。最重要的行业是大西洋鲑鱼（Salmo salar）的水产养殖，以及野生捕捞远洋鱼类，鳕鱼（Gadus morhua）和赛特（Pollachius virens）。加工成主要为鱼片的可销售产品会产生大量的海洋废弃物原料。水产养殖生产和加工的物流允许接近100％的利用率，而仅利用44％的白色鱼类剩余原料。在岸边养鱼可以在屠宰后立即加工剩余原料，这对于避免变质至关重要。鳕鱼和赛义德主要在海上被拖网渔船和沿海船队捕捞，克服了船上装卸和向岸运输的障碍，将剩余的原料加工成人类消费和动物饲料的高质量产品。这次审查的重点是挪威白鱼产业的价值链，其历史，现状和改进可能性，以更好地利用其余原材料。
