Outline of Final Research Achievements

To explain the risk of genetic disturbance by disorder transplantation, the spawning experiments and river investigations was conducted to reveal the difference of the spawning season among populations in the Japanese fluvial sculpin.
Populations of different environments start spawning at different times, even at the same temperature. It was considered began to spawn is irrelevant as the timing of temperature change, such as minimum temperature or increased to a specific water temperature. Therefore it was thought that the start spawning of the Japanese fluvial sculpin was determined not by the water temperature at that time but by other factors such as the light cycle.
