this context, the current increase in interest in alternative applications
for fish byproducts is crucial to both economic growth and sustainable
development. They constitute a rich source of chemicals with added
value, such as enzymes, bioactive peptides, and biopolymers, and
numerous research has been conducted to examine their potential
uses [8]. A metabolic process called fermentation involves drawing
energy from organic components without the aid of an outside
oxidizer. For this, lactic acid bacteria are used, a kind of solely
fermentative, organotrophic bacteria or cocci that are aero-tolerant
and generate lactic acid as the main result of fermentation. Since
ancient times, fermentation has been employed as a preserving
technique for all types of foods, including aquaculture feeds and
livestock feeds. However, since the fermentation of fish waste
increases the amounts of beneficial chemicals and also encourages a
drop in anti-nutrients through hydrolysis, it is now more important for
nutrition and health. Regarding hydrolysis aided by pH variations,
fermentation can offer a variety of advantages.
It should be highlighted that using fermentation has several key
advantages, including an increase in the efficiency of antioxidant
peptides that work in tandem with glutathione (GSH) to defend against
oxidative stress- related damage. Additionally, since proteins are
broken down into shorter peptides and amino acids during hydrolysis
throughout fermentation results in more digestible proteins, it can be
a very effective method for enhancing the fishmeal's nutritional
content, which is used as a source of protein in feed [24]. Assumi et
al., [4] used paddy straws to smash pineapple waste (peels, crown,
and pomace) at a moisture percentage of 8.7% to make an animal
feed block with molasses as a binding agent (wet basis). The study
also discovered that the block of animal feed made from waste
pineapple was reasonably stable in storage. As a result, using
pineapple waste instead of the usual green folder for animals is a
desirable alternative. According to a study by Mbuza et al., [25], most
farmers raise animals, including poultry. Poultries are more effective
than other livestock companies at turning feed into eggs and meats.
