Probiotics and Immunostimulants in Aquaculture

Abstract

Probiotics are organisms or substances that improve the balance of the host animal’s gut microbes and immunostimulants, also known as immunomodulators, adjuvants, or biological response modifiers, can stimulate the immune system. They can be given in the form of drugs or nutrients. They are considered natural and functional food ingredients and an alternative feeding strategy for immune regulation and antibiotic eradication. As dietary supplements in feed, immunostimulants and probiotics can generally improve the immunity, feed efficiency and growth performance of crustaceans and fish, even in small amounts.
