QUESTION 3 The biological relationship between the growth for the fish population and the size of the fish population is g = 15S(1 - S/5) where g is the growth of the fish population and S is the size of the population. The size of the harvest is a function of the amount of human effort expended b = 3ES where E is the level of effort. Market price of fish per unit is $100 and a constant marginal cost of effort is $50 If we rewrite the sustainable harvest/catch level equation in terms of effort level, E, then we have by = E- E
