dc.descriptionThe immune modulatory activity of diet long chain polyunsaturated fatty acids in fish has been previously demonstrated, although results for freshwater species are cont roversial. This study evaluates the effect of different dietar y lipids on freshwater catfish jundiá, Rhamdia quelen , survival and its non-specific response (phagocytosis) afte r being inoculated with the pathogen Aeromonas hydrophila . Five diets were offered to jundiá fingerlings during 150 days prior to challenge: cod liver oil (FO), sunflower oil (SO), linseed oil (LO), canola oil (CO) and coconut oil (CNO). Accumulated mortality was significantly lower in fish fed FO and CNO diets and higher in fish fed LO. In spite of the highest values observed for phagocytotic activity in CNO-fed fi sh (50.0 + 12.7%) and in FO-fed fish (45.0 + 10.5%) when compared to those fed other diets, no significant differences in phagocytosis were repo rted. Results show the relevance of a balanced dietary lipid source with adequa te concentrations of n-3 and n-6 series of fatty acids to prevent mortality after pathogen challenge.
