With a dramatically increasing world population and a world catch of fish of more than 140 million tons per year, there is obviously an increased need to utilize our marine sources with more intelligence and foresight. Large amounts of protein-rich by-products from the seafood industry along with under-utilized fish are discarded or processed into fish meal and fertilizer. Novel processing methods are needed to convert seafood by-products into more profitable and marketable products. Proteins from fish processing by-products can be modified to improve their quality, functional characteristics and nutritional value by enzymatic and chemical hydrolysis. Protein from fish by-products and under-utilized species, are rich in amino acids and could be used as fertilizer.
