There is a tremendous need to develop feed additives for culture of shrimp with the objectives to enhance production in short culture periods by facilitating faster weight gain, increase higher survival rate and improvement of overall health status, especially in high stocking densities. This study has investigated the effects of short usage of three immunostimulants on the growth of Penaeus monodon juvenile. The three modulators were vitamin-C, levamisole and chitin administered at different intervals (6 d, 10 d and 15 d). In general, the experimental animals fed on additive diets showed a weight gain. Among the three immunostimulants, the growth rate was high among animals fed with chitin. However, the cost effectiveness of these immunostimulants in the incorporation of shrimp feed and their mode of action as growth promoters remain to be explored
