Analysis of effects of fishery stock enhancement based on system dynamics model

From the perspective of system dynamics, considering aspects of fishery, ecology and society, we construct a simulative model of fishery enhancement and release of Penaeus chinensis in Shandong, and analyze the decision variables such as rational releasing number and fishing effort, so as to provide useful advices for further policy-making in programs of marine fishery stock enhancement. The method we introduce can also evaluate and forecast fishery abundance, yield, social benefits and ecological effects.
