Metabolic rates scale isometrically in larval fishes

چکیده
We estimated the rate of oxygen consumption of larval Atlantic mackerel Scomber scombrus at 3 temperatures (13, 16, 19 "C) while controlling rigorously for methodological biases. Routine metabolic rates (p1 O2 h-' ind.-l) increase with body weight (W, in mg) and temperature (T, in "C) as: RMR = 2.168 -W1 OoO e0.058 (rZ = 0.96). Thus metabolic rates scale isometrically with respect to body weight in larval Atlantic mackerel. This finding is at variance with results obtained for juvenile and adult fishes whlch follow an allometric relationship (WO ').

Coulometric measurement of oxygen consumption during development of marine invertebrate embryos and larvae
Determining the metabolic rate of larval invertebrates from aquatic habitats is complicated by the problems of small size and the scarcity of suitable measurement techniques. In this study, coulometric respirometry (a new technique for the study of marine embryos and larvae) was used to explore several issues associated with the rate of energy use during embryonic and larval development of mari...

Egg production of cultivated broodstocks of orange-spotted grouper, Epinephelus coioides and larvae rearing were surveyed in Iran from 2008 to 2012. . Broodstocks were obtained by rearing of 7 wild juveniles (587.57 ± 132.63 g body weight) which were caught from the north of Persian Gulf in October 2008 and reared to December 2012.. Captured juvenile fishes were fed using defrosted trash fish a...
متن کاملOntogenetic phase shifts in metabolism in a flounder Paralichthys olivaceus
Size-scaling metabolism is widely considered to be of significant importance in biology and ecology. Thus, allometric relationships between metabolic rate (VO2) and body mass (M), VO2 = a(i)Mb, have long been a topic of interest and speculation. It has been proposed that intraspecifically metabolic rate scales isometrically or near isometrically with body mass during the early life history in f...
