The Impact of Price on the Profits of Fishermen Exploiting Tritrophic Prey-Predator Fish Populations
Publikováno v:
International Journal of Differential Equations, Vol 2018 (2018)
We define and study a tritrophic bioeconomic model of Lotka-Volterra with a prey, middle predator, and top predator populations. These fish populations are exploited by two fishermen. We study the existence and the stability of the equilibrium points

Bioeconomic modeling of the exploitation of biological resources such as fisheries has gained importance in recent years. In this work we propose to define and study a bioeconomic equilibrium model for two fishermen who catch three species taking int

The presence of populations potentially harmful dinoflagellate phytoplankton like Oxyrrhis marina requires vigilance and control, because these species, in high density or under certain conditions, can have serious economic consequences and a negativ

In this paper, a mathematical model consisting of three populations with discrete time delays is considered. By analyzing the corresponding characteristic equations, the local stability of each of the feasible equilibria of the system is addressed an

In this study, a predator-prey interaction model with Holling type II functional response is studied. As the continuous threshold prey harvesting is introduced, the proposed model displays a dynami...

In this paper, a mathematical model consisting of Sardina pilchardus, Xiphias gladius and Bluefin tuna is considered. The differential system is based on the Lotka-Volterra scheme, considering a logistic growth for each population. Biological and bio
