Feed utilisation in Atlantic salmon kept at fluctuating oxygen saturation. A CREATE project
Atlantic salmon (initial weight 383 g) was kept at either stable oxygen saturation (>80%, control) or exposed to four daily drops in oxygen saturation to 70, 60 or 50% in a 68-days experiment. The fish was fed twice daily during normoxic (>80% oxygen saturation) periods. At termination of the...
