AB The search of bioactive compounds obtained from natural sources with beneficial effects in growth and health isan increasing trend in aquaculture. Wine by-products are an excellent source of such compounds, mostly phenolics, with demonstrated antioxidant and immunostimulant activities in vertebrates. The present study evaluated the effects of dietary inclusion (100 g/kg) of two wine by-products (grape pomace and lees) on growth,immune status and metabolism of juvenile golden gray mullet (Liza aurata), as well as the potential protectiveeffect of compounds present in the two by products against induced stress produced by moderate hypoxia. Results evidenced a significant positive effect of grape pomace on feed efficiency, as well as in different indicators ofmetabolic and immunological status of the fish. Also, a significant negative effect of wine lees on the functionaldiversity of intestinal microbiota was evidenced. Fish fed on diets containing any of the two by-products evidenced significantly lower levels of cortisol when challenged by hypoxia, this pointing to a protective effectmediated by their contents in phenolic compounds and suggesting an interesting and practical application forthese agricultural by-products.
