The purpose of this study was to determine the effect of chitosan scheduled on the non-specific immune mechanisms and disease resistance in Mugil Cephalus. Fish were fed with different doses of chitosan. The non-specific immune mechanisms were assessed in terms of growth parameter, counting of white blood cells (lymphocytes), Red blood cells (erythrocyte), Hematocrit, respiratory burst activity and cumulative survival rate. In our present study was (chitosan 2%) shows a significantly increased growth rate, WBC, RBC, Hematocrit (%), respiratory burst activity and cumulative survival rate compared with another experimental diet. Statistical analysis also proved the cumulative survival rate after 70 days of the challenge test, the experimental group showed 73% survival rate and in the control group, 100% survival was observed. This preliminary study indicates that chitosan could be used to promote the health status of fish in intensive fish aquaculture.
