To obtain high efficiency from animals, it is necessary to maximize the ability to benefit from feed and to protect animal health. One of the important applications in this direction is feed additives. Feed additives are plant and animal products and microorganisms that increase fish production and welfare, improve digestion and digestive system microflora and contribute to preserving nutrients and feed. Although plant and animal tissues are used in enzyme production, the use of microorganisms is in the first place. After using of molecular genetic techniques, the genes responsible for enzyme production were cloned in microorganisms, making it possible to produce enzymes more purely and cheaply on an industrial scale. It is a good alternative to use Bacillus strains that produce these enzymes as feed additives to support the immune system, reduce mortality, increase growth performance and provide resistance against diseases in fish.In this review, lichenase and laminarinase enzymes used in fish feeds and studies with Bacillus strains producing these enzymes were examined.
