Gce Model Questions Vol1 2025 Agricultural Science Question 22
Practice objective / multiple choice question 22 from the 2025 Gce Model Questions Vol1 Agricultural Science examination.
A fish population follows logistic growth \(\frac{dN}{dt}= rN\left(1-\frac{N}{K}\right)\) with intrinsic rate \(r = 0.5\) yr⁻¹ and carrying capacity \(K = 200{,}000\) tonnes. Harvest follows \(H = cEN\) where catchability \(c = 0.0001\) tonne per boat‑day and effort \(E\) is measured in boat‑days per year. Determine the effort that gives the maximum sustainable yield (MSY) and compute that yield.
