| Outline of Final Research Achievements |
The purpose of the present study is to obtain new knowledge through the application of fresh statistical modeling to various issues for fish population dynamics, and we conducted the following analyses:
1) Analysis of fishing efficiency for tuna species caught by purse seine fisheries in the Western Pacific Ocean based on propensity score method, 2) Catch prediction for juvenile bluefin tuna in the water close to Kagoshima based on support vector regression and generalized additive model, 3) Prediction of occurrence of red tide in the Yatsushiro sea using weather data and water survey data based on Tweedie regression analysis.
As a result, it showed the effect of catch reduction with large mesh size of the purse seine fisheries in study 1) and highly accurate predictive values were obtained in items 2) and 3).
