Use of bacteriophage vB_Pd_PDCC‐1 as biological control agent of <i>Photobacterium damselae</i> subsp. <i>damselae</i> during hatching of longfin yellowtail ( <i>Seriola rivoliana</i> ) eggs

Abstract

The Seriola genus includes several important commercial fish species due to its rapid growth and easy adaptability to confinement conditions. However, bacterial infections (especially those caused by Vibrio and Photobacterium species) are among the main limiting factors for the intensification of marine fish aquaculture, particularly during early development stages. Therefore, the use of phages, which are natural killers of bacteria, represents a promising strategy to reduce the mortality of farmed organisms caused by pathogenic bacteria.
