AQUATIC SCIENCES AND ENGINEERING
Sustainable seafood products could be achieved by considering sustainability in the seafood processing industry in addition to the measures to be taken in aquaculture and catching. For achieving sustainability in the seafood processing industry, assessment of the processing waste is necessary because seafood product processing results in waste materials such as skin, bones, shell, and internal organs. Fish wastes contain proteins and essential amino acids as those in the fishes. Therefore, these waste products can be considered as a rich nutrient source in terms of the nutritional value provided by fermentation methods. Fish waste can be used as fertilizer, fish silage, and for feed production. Similarly, shrimp processing wastes can be used for the production of astaxanthin and carotenoid pigment, and bivalve processing wastes can be used in agriculture, building trade, animal feed production, and water treatment. The most important issue regarding the assessment of seafood processing waste products is biopackaging and the evolution of edible films of chitin-chitosan through the components obtained from these wastes. Dumping the seafood processing wastes into the sea has a negative effect on both human health and the environment. Hence, assessment of these wastes is important in terms of sustainability and economical value.
