Abstract
Effectiveness of fasting against red sea bream iridoviral disease (RSIVD) in juvenile red sea breamPagrus majorwere evaluated. In an infection experiment, groups which were fasted for 10 or 20 days after challenge showed significantly lower mortalities than a feeding group. In a field trial test, in which a naturally RSIVD-prevailing batch of red sea bream was divided into 2 groups, a fasting group showed significantly lower mortality than a feeding group. These results indicate the effectiveness of fasting after virus infection against RSIVD.
