RESPONSE OF THE ARGENTINE PRAWN Artemesia longinaris BATE (DECAPODA, PENAEIDAE) TO DIETS SUPLEMENTED WITH IMMUNOSTIMULANTS Jorge L. Fenucci*, Victoria Bouchet and, Nora S. Haran Departamento de Ciencias Marinas, Facultad de Ciencias Exactas y Naturales, Universidad Nacional de Mar del Plata / CONICET Funes 3350. 7600 Mar del Plata, Argentina jfenucci@mdp.edu.ar The prawn Artemesia longinaris is an abundant penaeid species in the Argentine coastal waters. As the availability of this species undergoes yearly fluctuations, it is important to establish the feasibility of its culture. A 50 days trial was conducted to study the effect of different immunostimulants on growth and immune response on Artemesia longinaris. Individuals fed a complete feed, four semipurified diets containing probiotic (Saccharomyces boulardii), prebiotic (fructooligosaccharide, short chains), nutraceutic (Allium sativum, Drosera, Belladona and Pyrogenium) and a control diet were tested by triplicate in100laquaria at a density of 25 individuals/m2 .Immunological parameters, such as total haemocyte amount, protein concentration, and peroxidase and phenoloxidase activity in the plasma were determined for wild shrimp and individuals under culture conditions. Results of variables were linked with histological studies of the midgut gland. According to the data analysis (ANOVA) results indicated that percentage in weight gain of shrimp fed the diet containing probiotic are lower than those fed the control or complete diets(p
