碩士 === 國立臺灣大學 === 漁業科學研究所 === 104 === This study was conducted to evaluate the effects of diet with Ganoderma lucidum medium and 80 % ethanol extract of Ganoderma lucidum medium on growth, non-specific immune parameters and blood parameters in black carp (Mylopharyngodon piceus). In this experiment, the Ganoderma lucidum medium was supplemented at 0%, 0.75 %, 1.25 %, 2.5 %,5.0% to the basal diets, while the 80 % ethanol extract of Ganoderma lucidum medium was supplemented at 0%, 0.75 %, 1.25%,5.0 % to the basal diets. Each diet was fed to all groups of black carp (initial body weight: 13.03±1.81 g) for 6 weeks. Each group of the fish were weighed and measured non-specific immune parameters and blood parameters (including macrophages superoxide anion activity, phagocytic activity, lysozyme activity, alkaline phosphatase, triglycerol and total cholesterol)ware measured every two weeks. In this growth performances, the result showed no significant difference on the feed efficiency and weight gain percentage of black carp fed the Ganoderma lucidum medium containing diets supplemented. The experimental groups showed enhanced lysozyme activity, phagocytic activity, superoxide anion activity from the fourth week. We didn’t observed that ALP had shown much difference during the experimental period. However, it seems that the TG and T-Cho of experimental groups were similar or higher than the controlled groups at the end. These results can be concluded conducted that farmed fish fed with dietary 1.25 % Ganoderma lucidum medium supplementation and 2.5 % Ganoderma lucidum medium extract supplementation can enhance in growth, non-specific immunity and disease resistance.
