Assessment of the Sustainable Use of Fishery Resources and an Early Warning System

Abstract

Sustainable utilization of fishery resources is the essence and core issue of sustainable development of fishery. Without sustainable utilization of fishery resources, sustainable development of fishery can not be achieved. Therefore, comprehensive evaluation of sustainable utilization of fishery resources can objectively reflect the development potential of fishery resources, and track and monitor the implementation process of sustainable utilization strategy of fishery resources in various countries. As a new management mode and method, early warning system has its unique practical value in the management of marine fishery resources, because fishery resources are more vulnerable to the interference of external natural disasters, with higher risk and greater uncertainty than other resources. Therefore, this chapter systematically introduces the basic theories and methods of the evaluation and early warning system of the sustainable utilization of fishery resources. The main contents are as follows: (1) the basic principles and methods of the sustainable utilization of fishery resources, briefly introducing the concept, connotation, influencing factors and objectives of the sustainable utilization of fishery resources; (2) the basic theories and methods of the evaluation of sustainable utilization of fishery resources, putting forward the general steps of sustainable use evaluation, quantitative methods of comprehensive index evaluation, and sustainable use evaluation based on ecological nutrition level; (3) the basic theory of early warning system for sustainable use of fishery resources; and (4) the status of sustainable use of global marine fishery resources is analyzed as an example.
