Progress of theory and application of bio-economic model in fishery resources

Abstract:

The bio-economic model is the important study contents in economics of fishery resources, and it plays an important role in resource optimum allocation for fisheries. In this paper, the theory and development of bio-economic model for fisheries resources were reviewed and its developing tendency was discussed based on the collected references, in order to provide reference for the sustainable exploitation of fishery resources and scientific management, development strategy evaluation etc. The result shows that the bio-economic model of fisheries resources has been developed from the simple biology model to the sophisticated dynamic model including biological factors, ecological factors, economic factors, social factors, environmental factors, climate change and others at present. But the current research in China falls behind the overseas obviously, and it is still in the theory exploratory stage, only few applications in fisheries resources. With the development of mathematical modeling and computer simulation technology, scientists could simulate different fisheries management strategies and the changes in controllable factors, and impact optimization allocation of fishery resources by using bio-economic models. This could provide a scientific basis to make a decision for fisheries management, which will be one of the hot topics for bio-economics of fisheries resources in the future. However, it is necessary for the above studies to establish monitoring and assessment system of fishery resources, as well as the data collecting system in biological, economic, social and other aspects.
