碩士 / 國立海洋大學 / 水產養殖學系 / 87 / Fishes appear to utilize dietary carbohydrate poorly. It has been shown that carbohydrate is generally the major dietary source of energy in most domestic animals, however, it is considered to be of limited value in the nutrition of fish. Differences in carbohydrate digestion、utilization、absorption and metabolism between fish and mammals the major reasons. Causing dietary differences between these two animal groups. The objective of this experiment was to observe the variation of the blood glucose and glycosuria concentration within 24 hours after each injection of a certain glucose concentration in order to determine the glucose threshold for tilapia.The experiment 1, four levels of glucose concentrations 0, 0.75, 1.05, 1.35 g/dl had been injected, according to the body weight of tested fish. Experiment was designed be find threshold value of blood glucose for tilapia. The experiment 2, four levels of glucose concentrations 15, 22.5, 30, 45 g/dl had been injected. The second experimented was to understand the glucose of blood glucose and glycosuria after high concentration glucose injection.The result of experiment 1 indicates that the threshold of glucose in tilapia urine is at 87.25 mg/dl. The maximum glucose emission at the second hour after the injection of 15, 22.5, 30 g/dl glucose levels in second experiment. However, 45 g/dl level, the maximum glucose emission is at the first hour. The results of second experiment also indicate that the percentage of emission/injection decreased with the increasing of the injection concentration. Furthermore, the experiment 2 also show that 95% glucose inject to fish were not excreted to urine or keep in fish body.
