简要讨论了可以充分处理生态系统相关目标的问题。
Ecosystem objectives in fisheries management usually flow from high-level national
policies or strategies and international agreements. Consequently they are often
broadly stated and hence are difficult to incorporate directly in management plans.
Predicting the results of any management action is very uncertain because the
dynamics of ecosystems are complex and poorly understood. Methods to design and
evaluate operational management strategies have advanced considerably in the past
decade. These management-strategy-evaluation (MSE) methods rely on simulation
testing of the whole management process using performance measures derived from
operational objectives. The MSE approach involves selecting (operational) management
objectives, specifying performance measures, specifying alternative management
strategies, and evaluating these using simulation. The MSE framework emphasizes the
identification and modelling of uncertainties, and propagates these through to their
effects on the performance measures. The framework is outlined and illustrated by
three ecosystem-related applications: management of benthic habitats and broad fish
community composition; by-catch of species of high conservation value; and foodchain
interactions and dependencies. Challenges to be overcome before broader
ecosystem-related objectives can be fully handled are discussed briefly.
