项目摘要

申請者は申請書内の研究目的・内容[3]にある，社会経済学的な視点を取り入れた海洋保護区(MPA)の効果的な導入方法を明らかにする研究をすすめてきた。この研究において，漁業資源管理をするにあたり，努力や海洋保護区配分の最小単位である管理単位スケールの選択が，経済的便益や資源量などの資源管理の帰結に重大な影響を与えることを明らかにし，資源の生物学的特性に関する情報の他に，管理者らの意思決定も管理の成否に大きく関わる可能性を示唆した。また，伝統的な資源管理モデルを空間明示的なモデルに拡張し，最も重要な漁業資源管理の指標の一つである最大持続生産量（MSY）がどのように影響を受けるかを明らかにする研究を行った。モデルを空間明示的に拡張した場合，得られるMSYの値は必ず伝統的に使われてきたMSYの値より低くなることがわかった。すなわち，現実の空間構造を無視している伝統的なモデルは，MSYを過大に見積もっている可能性があることを示唆する。さらに，申請者は空間構造・齢構造を取り込んだ資源動態モデルを発展させ，MPAの導入が漁獲量を増加させるための理論的条件を初めて導きだした。この条件は，漁獲対象種１個体当たりの再生産数が中庸な値になるとき達成され，同時に漁獲高を増加させるという観点からみると，MPAは必ずしも有効な管理手段では無い事を示唆する。以上の３研究は現在論文にまとめ，審査中である

Applicants are required to apply for the purpose of the study [3]. The key points of social science are included in the input method of the results of the Marine Protection area (MPA). In this paper, we try to select the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum allocation level of marine protection area, the minimum distribution level of marine protection area, the minimum allocation level of The meaning of the manager decides whether the management is successful or not. For example, the system's resource management system does not use the information specified in the space. The most important financial resources management system refers to the maximum holding capacity (MSY) of environmental health in one year. The impact of the system is affected by the performance of the research bank. If you want to make sure that there is an express connection in the space, you can make sure that the MSY system is required to make sure that you need to make sure that you need to make sure that you have a low level of performance. Do not send information, do not pay attention to the use of the system, the MSY is too large to monitor the possibility of instigation. The applicant is responsible for creating the data acquisition system in the space, and the MPA adds the conditions of the theory of data acquisition to the data acquisition theory. According to the conditions, one kind of vehicle is in the middle of the cycle. At the same time, it is necessary for MPA to have the management tools in place to inform you that there is no need to instigate. The above three studies are now in the literature and in the literature.
