Dr. D. Radhika* and A. Mohaideen

ABSTRACT

Three type of seaweed was chosen for the study namely Gracilaria corticata, Ulva lactuca and Stocheospermum marginatum. The fish feed was formulated using 35% of seaweed. The fishes [Common carp (Cyprinus carpio) (weight 10±5g)] were divided into five groups four group were infected with A. hydrophila (1.6 × 104 CFU/fish) and one groups remained uninfected and this group along with negative control group was fed with control feed only and the infected groups were fed with seaweed mixed experimental diet. The experiment was carried out for 28 day. Every 7th day the blood parameters RBC, WBC were recorded the blood parameters have increased from first day to last day. From this study we can understand that the fish fed with seaweed incorporated died had good Immuno stimulants properties.
