A lake can support a maximum fish population (carrying capacity) of 200,000 fish. The intrinsic growth rate of the fish population is 0.4 per year. If a constant number of fish H is harvested each year, determine the largest value of H (in fish per year) that can be harvested sustainably (i.e., without causing the population to decline) and state the equilibrium fish population that will result under this harvest level.

Answer Options

A. Maximum sustainable harvest = 15,000 fish per year; equilibrium population = 125,000 fish
B. Maximum sustainable harvest = 20,000 fish per year; equilibrium population = 80,000 fish
C. Maximum sustainable harvest = 25,000 fish per year; equilibrium population = 75,000 fish
Correct Answer D. Maximum sustainable harvest = 20,000 fish per year; equilibrium population = 100,000 fish
Correct Answer
D
Correct Option:
Maximum sustainable harvest = 20,000 fish per year; equilibrium population = 100,000 fish
