Neco Model Questions Vol1 2018 Biology Question 19
Practice objective / multiple choice question 19 from the 2018 Neco Model Questions Vol1 Biology 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 \(r = 0.8\ \text{yr}^{-1}\) and the carrying capacity \(K = 500{,}000\) fish. The fishery removes fish at a constant rate \(H\) (fish per year). Determine the maximum constant harvest \(H_{\text{max}}\) that allows the population to persist (i.e., a non‑zero equilibrium). Give \(H_{\text{max}}\) rounded to the nearest whole number (fish per year).
