Japan JSPS Program: Influence of Thyroid Hormones on the Behavior of Larval Flounder

日本JSPS计划：甲状腺激素对幼体比目鱼行为的影响该奖项将提供补充支持，使国家海洋渔业服务局博弗特实验室，国家海洋和大气管理局，美国商务部，与日本京都大学的田中正治博士进行为期12个月的合作研究。利用伯克博士对美洲比目鱼的知识，研究小组将研究甲状腺激素对比目鱼幼虫从海洋迁移到沿海苗圃的影响。比目鱼和大多数海鱼一样，在海里产卵，它们的幼鱼被潮汐流带到沿海的苗圃。在迁徙过程中，比目鱼幼虫经历了由甲状腺激素控制的蜕变。Burke之前的研究表明，甲状腺激素可以诱导比目鱼的眼球迁移和肌肉发育。Burke和Tanaka将一起调查甲状腺激素是否真的引发了比目鱼的近岸迁徙，并预测破坏这种甲状腺活动的水毒物的影响。田中博士全年生产比目鱼幼虫的技术和他在比目鱼早期生活方面的专业知识将补充伯克博士在研究甲状腺激素对美国比目鱼的影响方面的经验，并将促进在美国和日本控制比目鱼的招募。

Japan JSPS Program: Influence of Thyroid Hormones on the Behavior of Larval Flounder This award will provide supplementary support to enable Dr. John Burke of the National Marine Fisheries Service Beaufort Laboratory, National Oceanic and Atmospheric Administration, U.S. Department of Commerce, to conduct collaborative research with Dr. Masaru Tanaka for 12 months at Kyoto University in Japan. Utilizing Dr. Burke's knowledge of American flounder, the team will study the effect thyroid hormones have on larval flounder immigrating from the sea to coastal nursery gounds. Flounder, like most marine fish, spawn at sea and their larvae are carried by tidal streams to coastal nursery grounds. During this migration, flounder larvae undergo a metamorphosis which is controlled by thyroid hormones. Burke's previous research has indicated that thyroid hormones induce eye migration as well as muscle development in flounder. Together, Burke and Tanaka will investigate whether the thyroid hormones actually initiate the flounders' inshore migration and will predict the impact of water toxicants which disrupt such thyroid activity. Dr. Tanaka's technique for producing flounder larvae year round and his expertise in the early life of flounder will complement Dr. Burke's experience with studying the effects of thyroid hormones on the American flounder and will facilitate the controlled recruitment of flounders in the United States and Japan.
