Abstract: Fish secrete different kinds of antimicrobial peptides (AMPs) which are positively charged short amino-acid-chain molecules involved in host defense mechanism. AMPs as the research hotspots in immunology are shown to have many advantages including broad-spectrum antibiotics, good thermal stability and unique antibacterial mechanism. The research progress of fish AMPs major fimctions is reviewed in this paper and its application perspective is also discussed.
