摘要

Aquatic animals harbor a great number of microorganisms with interesting biological and biochemical diversity. Besides serving as the natural defense system of the host, the utilization potential of this microbial association has been identified particularly as reservoirs of candidate probiotics. Host-derived probiotics have gained popularity in recent years as they offer an alternative source of beneficial microbes to the industry that is customarily dependent on the use of terrestrial microorganisms. At present, there is an overwhelming number of candidate probiotics in aquaculture but their large-scale application is restricted by bio-technological concerns and fragmentary documented probiotic actions. This paper presents the current understanding on the use of probiotics as a sustainable alternative that promotes health and welfare in fish and penaeids. In particular, this paper discusses the relevance of host microbiota and its potential as a source of candidate probiotics. It also revisits the interaction between probiotics and host immunity to provide the foundation of the immunomodulatory functions of host-derived probiotics. Several studies demonstrating the immunomodulatory capabilities of host-derived candidate probiotics are given to establish the current knowledge and provide avenues for future research and development in this thematic area of probiotics research in aquaculture.
