| dc.description.abstract | Insects have emerged as an alternative protein source for aquafeeds, and more recently, attention has turned into their lipidic fraction. This study evaluated the potential of black soldier fly larvae oil (BSFLO) to replace poultry oil (PO) in diets for two key Mediterranean aquaculture species: European seabass and gilthead seabream juveniles. A control diet containing 5.2% PO was formulated, along with three experimental diets in which PO was replaced by BSFLO at 33%, 66%, and 100% (1.7%, 3.4%, and 5.2% BSFLO dietary inclusion). Fish were fed to satiation for 8 weeks (gilthead seabream) and 12 weeks (European seabass) at 23.0 ± 0.7 °C and 22.8 ± 0.6 °C, respectively. All diets were well accepted by both species, with no adverse effects on feed intake. Growth performance and feed conversion ratio improved with the full replacement of PO by BSFLO, particularly in seabass. Increasing dietary levels of BSFLO led to greater lauric acid deposition in muscle, enhanced antioxidant capacity, and reduced lipid peroxidation in both species. The complete replacement of PO by BSFLO increased the muscle n-3/n-6 PUFA ratio in both seabass and seabream. Overall, BSFLO proved to be a promising lipid source in aquafeeds for seabass and seabream, with the total PO replacement by BSFLO yielding clear performance gains in seabass and contributing to a more favourable and stable muscle lipid profile (characterized by higher n-3/n-6 ratios, improved antioxidant status, and lower lipid peroxidation) which may support product quality in both species. | eng |
