meal, this approach is more cost-effective, eco-friendly, and safe.
During the early phase of the present work, the biochemical and
microbiological features of fish waste were analysed (Table. 1). The
fish waste utilized for this project had a tolerable amount of fishy odor
and its form.

2.2 Derived products that are turned into fishmeal and fish oil
Since the aquaculture sector, which is developing quickly, is by far the
biggest consumer of these goods, using by products by making
fishmeal, fish protein hydrolysates, and fish oil is a side way of making
healthy food available [10]. Fishmeal and fish oil prices have risen in
recent years, suggesting that consumers may no longer view these
items as low-quality [28]. By-products were the source of the available
fishmeal in 2007, but according to previous estimates, in 2010, this
percentage grew to 36% [10]. The heated raw materials are initially
