Byproduct utilization: Available and innovative technologies

One kilogram of byproducts not used commercial is one kilogram of mistakes. Many processors only focus on their main product and forget to take care of the byproducts in a correct manner. This influences the overall processing cost and operations in a negative way. It is desirable to process all byproducts into valuable products, first for human foods, second for pet food, and third as animal feed, pharmaceuticals, or fertilizer. Around the world a lot of scientist have developed new technologies and uses for fish byproducts but not too much has changed. The reason is simply that no one has successfully combined the use of innovative technology, processing method, and marketing of the product. During the last ten years a lot of new possibilities for processing fish and crustacean byproducts have been developed. These include not only mechanical tools but also new tools like enzymes. The combination of available fish byproducts, available technologies, and available markets is addressed.
