In certain parts of the globe, the fish processing plant by-products are used and transformed into low-market value products such as animal feed, fishmeal, and fertilizer (Chalamaiah et al., (2012),. However, in recent years, more studies are done on transforming the by-products into more valuable products called fish protein hydrolysates. This finding has created more attention to develop this product into human health supplements because of its high protein content with good organic compound balance and bioactive peptides (Chalamaiah et al., 2012). In certain European countries such as Norway, 97% of by-products from Norwegian aquaculture are being utilized. Consisting of discarded parts (head, bones, and internal organs) that are not fit for human consumption. This by-product, rather than being wasted and dumped, will be utilized to provide fish feed and indirectly helps towards a greener environment.
