Optimal control problem of a discrete spatiotemporal prey–predator three-species fishery model

In this work, we discuss a spatiotemporal discrete prey–predator model.  It consists of three compartments: prey, predator, and super-predator.  The proposed model describes the interaction between prey, predator, and super-predator in a region with a discrete displacement.  We also provide research on appropriate regional control strategies.  The controls are applied to the predator and the super-predator, respectively; they represent catching these in measured quantities in a space and a time chosen.  The aim is to increase the number of prey and reduce the number of

Dynamics of an ecological prey–predator model based on the generalized Hattaf fractional derivative

In this paper, we propose and analyze a fractional prey–predator  model with generalized Hattaf fractional (GHF) derivative.  We prove that our proposed model is ecologically and mathematically well-posed.  Furthermore, we show that our model has three equilibrium points.  Finally, we establish the stability of these equilibria.
