Gce Model Questions Vol1 2025 Agricultural Science Question 30
Practice objective / multiple choice question 30 from the 2025 Gce Model Questions Vol1 Agricultural Science examination.
A lake fish population follows the logistic growth model \(\dfrac{dP}{dt}=rP\left(1-\dfrac{P}{K}\right)\), where \(r = 0.35\) per year and the carrying capacity \(K = 8{,}000\) tonnes. The fishery wishes to maintain the population at no less than 60\% of the carrying capacity by applying a constant annual harvest \(H\). Determine the maximum constant harvest (in tonnes per year) that satisfies this requirement.
