The resting metabolic rate (RMR) of juvenile European sea bass Dicentrarchus labrax L. (47·5±1·5 g, 15–18 cm) was 126·2±2·5 mgO 2 kg −1 h −1 , and temporal patterns of oxygen consumption were not affcted by visual contact or social interaction with conspecifics. The results suggest that a group effect is not present in juvenile D. labrax , thus no selective advantage of shoaling is gained through lowered metabolism in this facultative schooling species.
