Management Strategy Evaluation

Regional fisheries management organizations (RFMOs) are increasingly developing and adopting a modernized system of management known as harvest strategies. This approach shifts managers’ focus from short-term quota-setting to a set of pre-agreed rules designed to achieve longer-term objectives, such as maximizing both catch and the likelihood of achieving and maintaining a healthy stock. At the heart of harvest strategies is a tool called management strategy evaluation (MSE), which scientists use to test different harvest strategies and determine which is most likely to achieve the RFMO’s objectives.

While MSE significantly improves managers’ understanding of the trade-offs of  pursuing different goals—and of the best path forward—the mathematical modeling that underpins MSE is highly complex. To help managers and other stakeholders better grasp MSE, The Ocean Foundation’s International Fisheries Conservation Project has developed a new animation that clearly describes the innerworkings of MSE and illustrates how the MSE tool is a critical component of any effective harvest strategy.

Fact Sheet

管理戦略評価(management strategy evaluation: MSE)は、科学者と管理者が漁業のシミュレーションを行い、 漁獲戦略(管理方式)候補のうちのどれが予め合意された管理目標を達成できるかを検証するために用いら れるツールである。この検証によって、最も高い成果を上げると考えられる漁獲戦略がどれかを見極めることが できる。このようにして選ばれた漁獲戦略は、不確実性の如何にかかわらず高い成果を上げることができる。 また、相対立する管理目標を比較衡量し重み付けが行われる。長期的な持続可能性、安定性、収益性を高める ため、漁獲戦略に基づく管理を行おうとする動きが世界で広まりつつある。選択された漁獲戦略が管理目標を 達成できるようにするためには、MSEが必要不可欠である。
