碩士 / 國立臺灣海洋大學 / 海洋生物研究所 / 103 / Environmental pollutions do impact marine organisms, such as sea turtles, and threate their survivorhsip. It has proved that high concentration of heavy metals in sea
turtles will reduce hatching success or decreased their immunity ability andaffect the health of sea turtle populations.This thesis is the first report on the heavy metal in the blood of sea turtle from bycatch, stranding alive, nesting or captive sea turtles in Taiwan. The purpose is to understand the relationship between heavy metal concentrations and the plasma biochemical of these sea turtles. Topics are divided into three parts, First part are the wild and stranded alive sea turtles, In this part, we find that the Cd、Se and Hg were higher in loggerhead turtle than green turtle(with carapace range from 70cm-90cm). In addition, hematocrit (PCV) does affect the concentration of heavy metals. In some special stranding cases : turtles swallowed tar ball or having eye infection, the blood contained high concentration of Hg、Cu and As. The second part are the nesting female.Higher concentration of Cd and Hg were found in turtles nest at Liouciou Island than Wangan and Lanyu Islands. The “Creatinine” values in plasma biochemistry were positively rrelated with Hg. The third part are the acptive and rehabilitated sea turtle, where the diet were different from the wild turtle.The As, Cu and Hg concentrations were higher than the wild turtles. The Pb concentration in the blood increased significantly with the duration of captive. The pond water in captivity; Da-Yi Temple had a higher concentration of Ni and found affected the captived sea turtles (Ni in blood concentration 3575.89µg / L ). The improper diets caused hyperphosphatemia and hypocalcemia of captive turtles have deteriorate the kidney fuction of the captive turtles. The damaged on this major metabolic organ will decrease the detoxification of sea turtles on heavy metals.. Even without direct evidence, the positive relationship between plasma biochemistry value with heavy metals suggests that the heavy metals do affect the health of sea turtles. This study emphasize the importance of pollutants control management, and can provide basline information for veterinarians and rehabilitation center to improve the captive environment and the diet of sea turtle.
