Daily oxygen consumption rhythms of Senegalese sole solea senegalensis (Kaup, 1...
Castanheira, F.; Martins, C. I. M.; Engrola, S.; Conceição, L. E. C.Senegalese sole is known to be a species with pronounced nocturnal feeding behaviour. However, as for most fish species, there is a lack of knowledge concerning the influence of such biological rhythmon metabolic rate. The aim of this study was to determine whether individual variation in routine and fed metabolic rate was affected by daily light–dark rhythms in juveniles of Senegalese sole. The individual oxyg...
Individual differences in metabolism predict coping styles in fish
Martins, C. I. M.; Castanheira, F.; Engrola, S.; Costas, B.; Conceição, L. E. C.Studies on metabolism usually rely on measurements of oxygen consumption obtained in respirometry chambers. Despite rigorous standardization there is still considerable interindividual variation in metabolic rates which is often ignored. Furthermore, housing in respirometry chambers implies handling and exposure to a new environment, conditions known to be a source of stress in animals. The extent of stress res...
