The amount of live feed and the type of live feed will affect larvae growth performance, survival rate and deformity. The partial substitution of live food has proven to be successful. The formulated microdiets supply with the live food to enable early weaning, for instance, certain substitutuion of rotifers with artificial diets has been achieved for Gilthead seabream larvae. Although weaning the larvae from Artemia onto a microdiet can be achieved at metamorphosis in many species, the early introduction of formulated diets for completely replacement of live food remains to be difficult. If a microdiet is well balanced, it is possible to reduce the live feed consumption without compromise the larval performance and survival, and it is the ultimate goal for the development of microdiets, and lots of efforts have been made by industry and academia during the last few decades. However, to our knowledge, studies on the effect of live feed reduction on the growth performance, survival and deformity rate of seabream larvae have never been published. It is therefore important to document the effect of live feed reduction on larvae performance.
