| Outline of Final Research Achievements |
This study tried to develop a method to detect feeding events of yellow phase Japanese eels using bio-logging, and investigated activities, behaviors and food habits of yellow eels in the brackish-water lake (Lake Jinzai) using biotelemetry and stomach content analysis. Results showed that feeding events of eels could not be detected by increase in body temperature in the peritoneal cavity after feeding. Moreover, activities of yellow eels closely associated with the light density. The core areas of the tagged eels were restricted to the proximity of the shore areas, probably because their principal prey organisms mainly inhabited there.
