Neco Model Questions Vol1 2023 Agricultural Science Question 30
Practice objective / multiple choice question 30 from the 2023 Neco Model Questions Vol1 Agricultural Science examination.
A lake fish population follows the logistic growth model \(\frac{dN}{dt}= rN\left(1-\frac{N}{K}\right)\) with intrinsic growth rate \(r = 0.4\) yr⁻¹ and carrying capacity \(K = 80,000\) fish. The fishery harvests a constant number \(H\) fish each year. To ensure the population never falls below 20,000 fish, determine the maximum constant annual harvest \(H_{\text{max}}\) that can be sustained indefinitely. Give your answer as a whole number of fish.
