Change in stock size 31 4. Explain what the y axis represents. From the diagram identify the stock size/s y2 is associated with. Explain why the respective equilibria you have identified are stable or unstable. Transform this model into one with economic content and identify the efficient level of effort (E*), the maximum sustained yield (Em) and the level of effort you would expect if the fishery were an open access fishery (Eo). 32 S D S S Stock size (biomass) Growth function Biological equilibrium w/out fishing i. Define and identify the Maximum Sustained Yeild (MSY) ii. If this MSY is not consistent with efficiency, identify the efficiency point iii. In both total and marginal terms explain why this is efficient.
