Optimal harvesting of prey-predator system with interval biological parameters: A bioeconomic model

► We study the prey-predator model under imprecise biological parameters. ► We consider impreciseness as a form of an interval in nature. ► We introduce parametric functional of an interval to study the model. ► We identify the equilibrium points of the model and discuss their stabilities. ► We discuss the bionomic equilibrium and optimal harvesting policy of the model.
