In this paper. we develop and study a mathematical model for the dynamics of Scomber colias and Thunnus thynnus prey-predator with parasitic helminths. We search to analyze a bioeconomic model in which both susceptible and infected prey populations Scomber colias are exposed to the predator Thunnus thynnus. with varying degrees of exposure. https://halohealthcarers.shop/product-category/reusable-masks/
