Effects of Ergosan and Vibromax to Prevent Vibriosis and WSSV in Litopeaneus vannamei

摘要

During the period of culture, immunostimulants and even vaccines may provide potential methods to protect shrimps from opportunistic and pathogenic agents. This study was designed to show the effects of Ergosan and Vibromax vaccine against WSSV and Vibrio harveyii in juvenile Litopeaneus vannamei and even growth and survival rate in PL stage. Among different treatments in PL stage, Ergosan significantly enhanced the body weight while in group treated with Ergosan and Vibromax the enhancement in survival rate was observed. Survival rate was also assessed by challenging with Vibrio harveyii and WSSV in juvenile stage. All treatments with Ergosan and Vibromax vaccine showed significant enhancement in survival rate compared to the control groups. This study indicates that Ergosan and Vibromax could be used to promote the health status of shrimp during the period of culture.
