Outline of Final Research Achievements

To investigate the stock structure of Pacific bluefin tuna in the Pacific Ocean, analysis of archival tag data was conducted. Analyses of chemical components of fish tissues such as otoliths and muscles as proxies of the environments they experience and mathematical modeling were also conducted. Archival tags have revealed the timing of trans-Pacific migrations from the transition region to the Eastern Pacific that appear to depend on their specific wintering areas in the Western Pacific. Our results also demonstrate that otolith oxygen stable isotope values and muscle nitrogen and carbon stable isotope values can provide precise and accurate estimates of their environments. The mathematical model (extended kinesis model) indicates that fish searching behavior for seeking favorable environments was an important parameter to construct the model.
