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

Abstract

The relationship between body mass (M) and metabolic rate was investigated through the assessment of active (RA) and standard (RS) metabolic rate at different life stages in zebrafish Danio rerio (5day-old larvae, 2month-old juveniles and 6month-old adults). Scaling exponents and constants were assessed for standard (RS=0·273M0·965 in mgO2g-1h-1) and active metabolic rate (RA=0·799M0·926 in mgO2g-1h-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. © 2014 The Fisheries Society of the British Isles.
