Neco 2023 Agricultural Science Question 45
Practice objective / multiple choice question 45 from the 2023 Neco Agricultural Science examination.
A fish population in a lake follows the logistic growth model \( \frac{dN}{dt}=rN\left(1-\frac{N}{K}\right) \) where the intrinsic rate of increase \(r = 0.4\) year\(^{-1}\) and the carrying capacity \(K = 200{,}000\) fish. The fishery harvests a constant number \(H\) of fish each year.\n\n(a) Determine the maximum constant harvest \(H_{\max}\) that can be sustained indefinitely without driving the population to extinction.\n(b) Under this maximum sustainable harvest, what is the equilibrium population size?
