##### Sharks and Sardines with Fishing We apply the classical predator-prey model of Volterra: dxldt =ax bxy, dyldt = -cx dxy, where X denotes the population of sardines (prey) and y the population of sharks (predators): We now subtract a term from each equation that accounts for the depletion of both species due to external fishing: If we fish each species at the same rate, then the Volterra model becomes dx/dt ax bxy fx, dyfdt =-cy + dxy fy; where the constant f2 0 denotes the "fishing" ef
