Effect of Oregano Essential Oil on Growth and Composition of Gut Prokaryote Microbiota on Striped Bass (Morone saxatilis).

ABSTRACT: Sustainable strategies, such as oregano essential oil (OEO), are being assessed to improve farmed fish's health and performance. Several studies in freshwater species describe the beneficial effects of OEO as a dietary supplement. Nonetheless, information about its use in marine fish is scarce. Hereby, this study consisted of four experimental groups: a control and three levels of OEO dietary inclusion (OEO75 (0.75 mL/kg), OEO100 (1.0 mL/kg), and OEO125 (1.25 mL/kg)) with 23 fish of 110 ± 1.2 g per tank (n = 276) in a seawater flow-through system. After 70 days, data for growth parameters and samples for gut microbiota were taken. The final weight of OEO75 was higher (242.3 ± 24.2 g), and its feed conversion rate (0.91 ± 0.0) was reduced. However, these differences could be related
