Dose-dependent benefits of dietary yeast cell wall supplementation on the growth performance and stress resilience of the European seabass (Dicentrarchus labrax).

ABSTRACT: Preventive health management is central to modern aquaculture practices, within which functional feed additives are a key tool to optimising fish robustness and disease resilience. Despite being well documented, only few studies have assessed the dose-effect of graded levels of S. cerevisiae yeast cell wall (YCW) on fish performance and mucosal barrier immunity. A 9-week trial was conducted to assess the impact of graded levels of YCW on the performance and mucosal barriers of the European seabass under period: (1) non-challenge (43 days) then (2) with an applied husbandry stressors (20 days) in the form of high stocking density, low water oxygen level, and repetitive handling. The four experimental diets were produced by incorporating graded levels of YCW (0.0, control; 1.5; 3.0 or 4.5 kg
