AbstractFishmeal (FM) and fish oil (FO) are the reference protein and fat sources in aquafeeds, but replacing them is industry priority due to sustainability and future availability issues. However, FM and FO are high-quality raw materials and their replacement can lead to impaired fish growth and immune status (e.g., Conceição et al. 2012). FM and FO in addition to balanced amino acid and fatty acid profiles, also bring micronutrients which are often not present in the most used alternative ingredients, e.g. from plant origin. Phaeodactilum is a microalgae rich in micronutrients and bioactive compounds such as fucoxanthin and polyunsaturated fatty acids (PUFA) particularly eicosapentaenoic acid (EPA) (Gilbert-López et al., 2014). This study intends to evaluate the effects of dietary supplementation with Phaeodactilum tricornutum incorporated in feed by two different processes, either as whole cells (integral cell wall) or broken cells (disrupted cell wall) on fish health status and performance, in a feed formulation scenario of a zero fish meal, reduced fish oil.
