10. For a fish population modeled by a depensation growth model, we have, when there is harvesting, where d dt N= F(N) H(N), and H(N) = qEN. F(N) N (N/N - 1)(1-N/K) a. Find (and plot, freehand) the sustained yield H(3) 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 №3 is the nontrivial stable equilibrium of N and N is the unstable equilibrium. b. Find the E (= Emax), where the two curves in (a) merge (this happens when NN3). What happens to the fishery and the fish population when E = Emax? = c. Suppose harvesting is done at effort level E = Emax for a while so that the fish population is below what was thought of as the “sustainable” N (which is equal to №2, so actually it is not really sustainable). Realizing that there is a problem, the government puts in a fishing limit that reduces the effort E to slightly below Emax. Can the fishery recover?
