Abstract: A 45-days trial was performed to assess the effect of fermented sunflower oil cake (FSFC) on digestive enzymes activity and immune responses in Penaeus vannamei. Five iso-nitrogenous diets were formulated with FSFC (0, 25, 50, 75 and 100 g/kg) by substituting fishmeal (w/w). A total of 300 juveniles (3.08±0.07 g) were randomly distributed to the experimental tanks (twenty shrimp per tank) with three replications for each treatment. Results revealed that protease activity was decreased (P<0.05) with increasing the inclusion level of FSFC. Shrimp fed with FSFC 75 diets had a higher (P<0.05) amylase activity (0.816 U/mg of protein) than others. Lipase activity did not vary significantly among the treatments. Total haemocyte count was 11.24-18.06x106 cells/ml. Control group has shown the highest activity of phenoloxidase (2.85 dopachrome/ml). Results concluded that fishmeal could be partially substituted with FSFC without having any negative impact on health status of P. vannamei.
