Abstract: To study the effects of water temperature and intraspecies standard metabolic rate (SMR) difference on the excess oxygen consumption (EPOC) of juvenile Carassius auratus after its exhaustive exercise, this paper measured the SMR and oxygen consumption (MO₂) of juvenile C. auratus during the recovery process after exhaustive exercise at 15 and 25 ℃, and calculated the total amount of EPOC after exhaustive exercise and the maximal metabolic rate (MMR), metabolic scope, and recovery duration. The values of SMR, MMR, metabolic scope, and EPOC were significantly higher at 25 ℃ than at 15 ℃ (P<0.01), whereas the recovery duration at 15 ℃ and 25 ℃ showed no significant difference. At the two temperatures, the individuals SMR was positively correlated with MMR but negatively correlated with EPOC, and the variation of temperature had no significant effects on these relationships. The results indicated that water temperature had significant effects on the excessive oxygen consumption parameters except recovery duration after exhaustive exercise, but no significant effects on the relationships between SMR and MMR or EPOC.
