• Resumen

  • [EN]: Aquaculture is one of the major consumers of fish meal and fish oil. However, the continuous expansion of aquaculture and the decreasing global availability of marine oil and fish meal force the industry to explore alternative and sustainable alimentary sources for fish feeds. To address this issue, the feasibility of combined replacement of fish meal and oil by vegetable ingredients was investigated in gilthead sea bream (Sparus aurata) and dietary effect on growth performance and tissue fatty acid profiles were examined. Four diets with a low level of fish meal inclusion were supplemented with lysine (0.55%) and contained soy lecithin (1%). Added oil was either fish oil (FO diet) or a blend of a vegetable oil mixture (17:58:25 of rapeseed:linseed:palm oils) replacing fish oil at 33, 66 and 100% (33VO, 66VO and VO diets).
