Under the assumption of rational people and limited common pool resources, individuals will extract as many common pool resources as possible in order to maximize their interests. Marine resources are typical common pool resources. As the number of marine catches increases year by year, the marine environment has been severely damaged. In order to protect marine biological resources and reduce the occurrence of excessive extraction, this paper employs the method of experimental economics to study the individual's extraction behavior of common pool resources by setting up a two-stage experiment in the selection of resources entering the common pool and the number of resources extracted. We also introduce two important factors, information and risk, in the experiment, and study the individual's common pool resource extraction behavior in the face of various risk changes. The experimental results show that the process of information disclosure and risk changes will affect the selection of individual resources and the number of resources extracted to a certain extent. The conclusion can provide policy enlightenment for public governance. For example, disclosing the information on the number of resource extractions can help individuals adjust the number of resource extractions, and formulating corresponding resource management policies according to weather changes can prevent individuals from misjudging risks and leading to irrational extraction behaviors.
