This study aimed to investigate the influence of increasing salinity concentrations on some indicators of energy consumption such as dissolved oxygen consumption, the consumed energy, as well as the levels of blood glucose in Carassius auratus (Goldfish), because of their direct relation with the metabolism rates when fish are exposed to exertion. Fish with an average weight of 37.5+2.5 g were exposed to four salinity concentrations 0.1, 3, 6, and 9 grams per 1 liter; concentration represented four treatments, and the first one is control. Results showed that there was increase in the rate of oxygen consumption to 92.34, 126.24, and 158.86 mg O2/kg/hour in the salinity concentration levels 3, 6, and 9 respectively, compared to the control (88.16 mg O2/kg/hour). This increase in oxygen consumption affected the consumption rate of energy, which achieved 0.311, 0.425, and 0.535 kilo calories in the salinity concentrations of 3, 6, and 9 gram/L liter, respectively, compared to the control (0.297 kilo calories/kg/hour). Concerning blood glucose levels rose in the salinity concentrations of 3, 6, and 9 gram/L liter to 68.33, 87.88, and 108.69 mg/100mL, respectively, compared to the control (66.33 mg/100 mL).
