Fish oil substitution by soybean oil in Diplodus puntazzo: Performance fatty acid profile and liver histology

[EN] The present study was performed to determine the effect of soybean oil on the performance and liver histology in sharpsnout sea bream. Four experimental diets were formulated containing 0%, 25%, 50% and 75% of soybean oil substituting of fish oil. Fish weighing 35 g were fed for 84 days. Increasing the level of soybean oil had no significant effects on growth and feed efficiency parameters. Biometrics, body composition, protein- and energy- efficiency were not affected by the fish oil replacement. Muscle and liver fatty acids reflected fish oil substitution. Moreover, histology did not show statistical differences among treatments.This research was supported by grants from the Planes Nacionales de Acuicultura (JACUMAR) in Spain.Nogales Mérida, S.; Martínez-Llorens, S.; Moñino López, AV.; Jover Cerda, M.; Tomas-Vidal, A.
