“…A wide variety of protein-rich by-products have been used for making fish silage (Aspevik et al, 2017;Gildberg, 2002;Martínez-Alvarez et al, 2015). However, recovered protein from by-products could be used for the development of human food products, dietary supplements and pharmaceuticals (Ambigaipalan and Shahidi 2017;Hayes et al, 2018;Karim and Bhat, 2009;Kim and Mendis, 2006;Wasswa, et al, 2007). Proteins could be recovered by different processes using mechanical separation from frames, base extraction, or hydrolysis Sila and Bougatef, 2016).…”

The world fisheries resources have exceeded 160 million tons in recent years. However, every year a considerable amount of total catch is discarded as by-catch or as processing leftovers, and that includes trimmings, fins, frames, heads, skin, viscera and among others. In addition, a large quantity of processing by-products is accumulated as shells of crustaceans and shellfish from marine bioprocessing plants. Recognition of the limited marine resources and the increasing environmental pollution has emphasized the need for better utilization of the by-products. Marine by-products contain valuable protein and lipid fractions, minerals, enzymes as well as many other components. The major fraction of by-products are used for feed production—in making fish meal/oil, but this has low profitability. However, there are many ways in which the fish and shellfish waste could be better utilized, including the production of novel food ingredients, nutraceuticals, pharmaceuticals, biomedical materials, fine chemicals, and other value-added products. In recent times, much research is conducted in order to explore the possible uses of different by-products. This contribution primarily covers the characteristics and utilization of the main ingredients such as protein, lipid, chitin and its derivatives, enzymes, carotenoids, and minerals originating from marine by-products.

“…The seafood processing industries generate large amounts of side streams that can be a raw material for the production of marine proteins (protein isolate, fishmeal, silage, and hydrolysates), oils rich in long chain n-3 polyunsaturated fatty acids (LC n-3 PUFA), and preparation of high-value compounds such as vitamins, enzymes and minerals for various nutritional, pharmaceutical, and biomedical applications (Kim, 2014). When using fish processing side streams for the development of food ingredients, they must be handled in a food-grade manner, following basic operational and environmental conditions required to produce safe foods (Hayes, 2018). Hereafter, we will use the term "by-product" to refer to food processing industry outputs used in the animal feed industry, "co-product" will be used for outputs that are food grade and can be used for human consumption; "sidestream" is the collective term for both.…”
