Abstract:

Background: A 60-day experiment was conducted to evaluate the fucoidan effect of Cystoseira indica on the growth performance, survival, immune response and disease resistance to Vibrio parahaemolyticus in Penaeus vannamei at College of Fisheries Science, Kamdhenu University, Veraval - 362 265, Gujarat, India.

Methods: The study used three different Cystoseira indica fucoidan (CIF) extracted diets viz. T1(0.5% CIF), T2 (1% CIF) and T3 (2% CIF) along with the control treatment to the larvae of Penaeus vannamei with a stocking density 20 numbers/tank of average body weight 0.012g were stocked in 60 L capacity rectangular plastic tanks. Each treatment were kept in triplicate factor followed the completely randomized design (CRD).

Results: P. vannamei expressed a better growth performance in terms of WG, SGR, FCR, PER and immune response in terms of PO and NBT. A lower mortality was observed in T3 (2% CIF) diet. Based on the results, it can be concluded that T3 (2% CIF) diet showed the better growth, immune response and disease resistance to Vibrio parahaemolyticus suspension (1×10⁷ cfu ml⁻¹) in Penaeus vannamei.
