Abstract

In this paper, the theory of Multi-Objective Optimal Sustainable Yield is developed based on the theory of optimal sustainable yield, which makes multiple objectives about biology, environment. economy and society optimization. The Strategy of Satisfied Sustainable Yield is an approach to determine a satisfied yield close to optimum yield, resulted from the principle of Multiobjective optimal sustainable yield, and a managing strategy to aid satisfied yield. The approach provides bases for the management of biological resource. The Strategy of Satisfied Sustainable Yield for Waterhyacinth. as a case study, is discussed.
