Dietary Wheat Gluten Alters the Gut Microbiome and Plasma Taurine Levels in European Sea Bass (Dicentrarchus labrax)

Incorporating environmentally sustainable plant-based protein sources into aquafeeds is a priority for the aquaculture industry. Wheat gluten as plant source has been successfully integrated feeds several fish species. However, unique nutritional requirements and potential intolerances necessitate evaluation of diets by Previous work our laboratory indicated that wheat at less than 4% inclusion in compound feed had negative impact on growth survival rate juvenile cobia (Rachycentron canadum). In current study, we evaluated effects diet European sea bass (Dicentrarchus labrax). No major differences were observed terms rate, plasma biochemical parameters, detectable induction IgM, IgT, or factors capable binding gliadin response to dietary gluten. levels taurine doubled fed gluten, there considerable changes intestinal microbiome. Despite these measurable changes, data suggest well tolerated formulation.
