Résumé
The relationship between body mass and metabolic rate was investigated through the assessment of active and standard metabolic rate at different life stages in zebrafish Danio rerio (5 day-old larvae, 2 month-old juveniles and 6 month-old adults). Scaling exponents and constants were assessed for standard (RS=0.273M0.965 in mgO2.g-1.h-1) and active metabolic rate (RA=0.799M0.926 in mgO2.g-1.h-1). These data provide the basis for further experiments regarding the effects of environmental factors on aerobic metabolism throughout the life cycle of this species.
