I need help with this questions, it is all one big question!

1. Suppose that growth rate ofthe Atka mackerel (Pleurogrammus monopterygius) stock in the Western Aleutian Islands fits a logistic function, with parameter values listed in Table 1 below. a. What is the stock level that corresponds to maximum sustainable yield (MSY)? Depict your solution on a graph with growth on the vertical axis and the stock level on the horizontal axis. Table 1. Parameter values Parameter a K q p W Value .8 3,000 0.025 100 400 Units 1/year tons 1/trip S/ton S/trip 2. Now assume that there is a single decision maker (a hypothetical "sole owner\3. Consider a scenario where the Western Aleutian Island Atka mackerel fishery is open access, with all current and potential participants facing the same landing price and sharing vessel 1's cost structure. a. What level of effort will be active in this fishery in equilibrium under open access? Explain your reasoning. b. On a new graph with dollars on the vertical axis and effort on the horizontal axis, depict your solution to problem #3.a. c. Taking your graph from problem #3.b, add the solutions to problems #1.a. and #2.a (making adjustments as necessary so all solutions are in the same units). If the three solutions you draw differ, explain how and why. 20f2
