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. The equation representing a sustainable harvest/catch level, b s, in S is b s = S(1 - S/ ).

Question
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.
The equation representing a sustainable harvest/catch level, b s, in S is b s =
S(1 - S/
).
