INFLUENCE OF TEMPERATURE AND SALINITY ON THE IMMUNE SYSTEM OF THE ARGENTINE SHRIMP, Artemesia longinaris BATE UNDER CULTURE CONDITIONS Jorge L. Fenucci*,Vanesa Arakaki and Nora S. Haran Departamento de Ciencias Marinas, Facultad de Ciencias Exactas y Naturales, Universidad Nacional de Mar del Plata/CONICET Funes 3350.B7602AYL, Mar del Plata. Argentina. jfenucci@mdp.edu.ar The shrimp Artemesia longinaris is 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 culturing. The response of innate immune system on the shrimp under culture condition stress was studied. Groups of 9 juvenile individuals fed with a complete diet were acclimated for 35 days at optimal(control) environmental conditions (35 ups, 19°C), high salinity (41 ups, 19°C), low salinity (27 ups, 19°C) and high temperature (35 ups, 25°C). Immunological parameters, such as total haemocyte amount, protein concentration and peroxidase and phenoloxidase activity in the plasma were determined for wild and individuals under culture conditions. Results of variables were link with the histology study of the hepatopancreas. According to the data analysis (ANOVA) significant differences (p
