Allometric relationship between body mass and aerobic metabolism in zebrafish Danio rerio

The relationship between body mass (M) and metabolic rate was investigated through the assessment of active (R-A) and standard (R-S) 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 (R-S = 0 center dot 273M(0 center dot 965) in mgO(2) g(-1) h(-1)) and active metabolic rate (R-A = 0 center dot 799M(0 center dot 926) in mgO(2) 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.
