Abstract

and zooplankton interacting species to observe the impact of environmental toxin (Te)
and rate of toxin librated by phytoplankton () on the survival of plankton species and
termination of planktonic blooms. The growth of phytoplankton is affected by environmental
toxins released by industries and by natural resources. The growth of zooplankton
depends upon the growth of phytoplankton by Holling type-II functional response. It is
determined that the given model system is bounded and positive under certain conditions.
The conditional local stability of different equilibrium points is obtained. The study of
different parameters has been carried out to discuss the occurrence and non-occurrence
of planktonic blooms. The Hopf-bifurcation analysis has been studied by taking Te and
() as bifurcation parameters which lead to unstable the plankton system through the
existence of periodic oscillations with the occurrence of planktonic blooms.
Key Words: Plankton, Environmental toxin, Hopf-bifurcation, Toxin librated by phytoplankton
