Differential Reshaping of Skin and Intestinal Microbiota by Stocking Density and Oxygen Availability in Farmed Gilthead Sea Bream (Sparus aurata): A Behavioral and Network-Based Integrative Approach.

ABSTRACT: Fish were kept for six weeks at three different initial stocking densities and water O₂ concentrations (low-LD, 8.5 kg/m³ and 95-70% O₂ saturation; medium-MD, 17 kg/m³ and 55-75% O₂ saturation; high-HD, 25 kg/m³ and 60-45% O₂ saturation), with water temperature increasing from 19 °C to 26-27 °C. The improvement in growth performance with the decrease in stocking density was related to changes in skin and intestinal mucosal microbiomes. Changes in microbiome composition were higher in skin, with an increased abundance of Alteromonas and Massilia in HD fish. However, these bacteria genera were mutually exclusive, and Alteromonas abundance was related to a reactive behavior and systemic growth re
