A study of plankton bloom in a phytoplankton-zooplankton model with viral infection.

The present paper explores a four-dimensional mathematical model with viral infection of plankton bloom in a phytoplankton-zooplankton, Mathematical modeling on plankton dynamics is a great interest in researchers. Here we discuss the mass action law for nutrient. We also discuss the existence and local stability of equilibrium points. To investigate the biological implication of threshold parameters and community structure. We analysis the local stability of interior equilibrium point and hopfrbifurcation. Also discuss the Permanence of the system for future time. In this paper we observed that stable distribution, periodic oscillation and periodic solution. [ABSTRACT FROM AUTHOR]
