Dynamics Analysis of Fishery Economic Models with Variable Price
In recent years,with the improvement of fishery productivity and the growing de-mand for food from a constantly expanding population,human exploitation of fishery resources has been intensifying,leading to widespread instances of overfishing.Given the severe chal-lenges faced by fishery resources,it is necessary to manage the development of these resources in a more scientifically and effectively manner in order to address the increasingly urgent eco-logical environment and the declining and deteriorating fishery resources.This study considers the impact of market price fluctuations on the development of fishery resources and establishes a model for fishery resource development with price fluctuations.Firstly,the existence of equi-librium points is discussed.Then,the stability of the equilibrium points is investigated by analyzing the roots of the characteristic equation.Finally,the correctness of the theoretical analysis is verified through numerical simulations.The resultsof the study indicate that price fluctuations have a significant impact on the dynamics of the model,and changes in price and fishing costs can affect whether or not fishing activities take place.
