For a fish population modeled by a depensation growth model, we have, when there is harvesting, dt where and H(N)-qEN a. Find (and plot, freehand) the sustained yield H(N;) as a function of effort E, and the unsustainable yield H(N2), also as a function of E (and plot on the same figure). Here Ni is the nontrivial stable equilibrium of N and N2 is the unstable equilibrium b. Find the E (F Emax), where the two curves in (a) merge (this happens when Ni- N;). What happens to the fishery and the fish population when E Emax c. Suppose harvesting is done at effort level E-Em for a while so that max the fish population is below what was thought of as the "sustainable" N
