Research Abstract

In order to elucidate the mechanisms of lamprey maturation, both molecular genetical and ecological studies has been conducted. The different gene expression were detected according to the metamorphosis and maturation stages between life histories. Ecological studies indicated the importance of both food resource and water temperature for determination of lamprey maturation.
