A lake fish population follows the logistic growth model \(\frac{dN}{dt}=rN\left(1-\frac{N}{K}\right)\) with intrinsic growth rate \(r=0.4\) per year and carrying capacity \(K=8000\) fish. A constant annual harvest of \(H\) fish is imposed. Determine the maximum constant harvest \(H_{max}\) (in fish per year) that can be sustained without driving the population to extinction, and state the equilibrium population size at this harvest.

Answer Options

A. Maximum sustainable harvest: 400 fish per year; equilibrium population: 6000 fish
Correct Answer B. Maximum sustainable harvest: 800 fish per year; equilibrium population: 4000 fish
C. Maximum sustainable harvest: 1600 fish per year; equilibrium population: 2000 fish
D. Maximum sustainable harvest: 800 fish per year; equilibrium population: 2000 fish
Correct Answer
B
Correct Option:
Maximum sustainable harvest: 800 fish per year; equilibrium population: 4000 fish
