Neco Model Questions Vol1 2020 Agricultural Science Question 35
Practice objective / multiple choice question 35 from the 2020 Neco Model Questions Vol1 Agricultural Science examination.
A lake's fish population follows logistic growth \( \frac{dN}{dt}= rN\left(1-\frac{N}{K}\right) \) with intrinsic growth rate \(r=0.4\) year⁻¹ and carrying capacity \(K=80\,000\) fish. The fishery manager wants to set a constant annual harvest \(H\) (fish year⁻¹) that gives the maximum sustainable yield while ensuring the population never falls below 20 000 fish. Determine the greatest constant harvest \(H\) (fish per year) that satisfies the constraint.
