Positive Poisson integrators for approximating Lotka-Volterra predator-prey model will be described. They are based on the trasformation of the systems into the field of positive solutions by means of a log trasformation. Splitting and composition schemes for positive approximation of population dynamics with prey logistic growth and Holling II type functional response will be also introduced.
