| Summary: | 碩士 === 國立臺灣海洋大學 === 食品科學系 === 98 === In order to know the zinc concentration in the hematopoietic tissues (head kidney, kidney and spleen) of the common carp, we respectively analyze the common carp from fish market (stressed fish) and from the laboratory (rested fish). The zinc concentration in the blood, head kidney, kidney and spleen of grass carp, silver carp and tilapia were also studied for a comparison. Zinc concentration in the blood of the common carp from fish market is 18.1±16.9 μg/ml whole blood, with a great individual difference. The zinc concentration in the head kidney, kidney and spleen of the common carp from fish market are 665±547,268±227 and 204±260 μg/g fresh tissue, respectively. The head kidney, kidney and spleen of the grass carp, silver carp and tilapia are between 10-20 μg/g fresh tissue with little individual difference among different species and different tissues. However, the zinc concentration in the blood, head kidney, kidney and spleen of common carp (stressed fish) are significantly higher than that of the laboratory (rested fish), and the main differences between the two groups are the zinc in the cells. The experiment also indicates that when the common carp were fed high zinc diet, the zinc will accumulate in the hematopoietic tissue (head kidney, kidney and spleen).
