The aquaculture industry has developed significantly over recent decades and is, today, one of the fastest-growing food production sectors in the world. One of the most important problems that affect aquaculture is the appearance of infectious diseases. Among bacterial diseases affecting cultured salmonid fish, Bacterial Cold-Water Disease, caused by Flavobacterium psychrophilum, produces high mortality and morbidity and consequently, economical losses worldwide.

Attempts to control this situation through the use of antimicrobials have been limited due to the rapid appearance of antibiotic-resistant bacteria. Moreover, the determinants of antibiotic resistance that have emerged and selected in this aquatic environment have the potential of being transmitted by horizontal gene transfer to bacteria of the terrestrial environment, including human and animal pathogens.

Evidence indicating that antibiotic-resistant bacteria and antibiotic resistance determinants pass from the aquatic to the terrestrial environment has resulted in a drastic restriction of the use of antibiotics in aquaculture in many countries. For this reason, it is important to find new products with antimicrobial activity without the aforementioned undesirable effects of antibiotics.
