STUDY ON IMMUNOSTIMULATORY PROPERTY OF FEW SEAWEEDS INJECTED INTRAPERITONEALLY
Objective: Three type of seaweed was chosen for the study namely Gracilaria corticata, Ulva lactuca and Stocheospermum marginatum and was extracted with ethanol.
Methods: The fishes [Common carp (Cyprinus carpio) (weight 10Â±5g)] were divided into five groups. They were infected with A. hydrophila (1.6 Ã— 104 CFU/fish). The infected three groups were injected with seaweed extract (0.20 mg) suspended in saline solution. One group was injected only saline control the other one group was injected with ciprofloxacin (0.20 mg) (standard) suspended in saline. The experiment was carried out for 28 d. Every seven days interval the fishes were injected with seaweed extract and blood parameters of RBC, WBC, HB, Ht, MCV, MCH, and MCHC were recorded.
Results: The MCHC value of Gracilaria corticata was recorded in 28th day (29.28Â±1.15) g/l. In Stocheospermum marginatum, the MCHC value was found in (27.19Â±1.62) g/l on 28th day. The Ulva lactuca had a MCHC value of (26.80Â±2) g/l on 28th day.Conclusion: From this study, we can understand that the fish injected with seaweed extracts as good Immunostimulants properties.Â
