antimicrobial peptides and their importance in aquaculture

Intensive fish culture plays an essential role in fish health. the high fish density and unfavourable conditions of water quality factors are potential sources of stress in fish, which often predispose fish to diseases. infected fish are usually treated using antibiotics, which are not always effective, and the accumulation of these compounds in fish meat endangers the consumers' health. in addition, the excessive use of antibiotics has caused the emergence of antibiotic-resistant pathogens which accounts for a major financial threat to the aquaculture industry. fish antimicrobial peptides (amps) can potentially replace conventional commercial antibiotics in the aquaculture industry due to a wide range of antimicrobial activity, potential of boosting the immune system, and activity at different temperatures and salinities. therefore, introducing new antimicrobial compounds to treat fish diseases can greatly contribute to the aquaculture industry.
