Waec Model Questions Vol1 2024 Agricultural Science Question 2
Practice objective / multiple choice question 2 from the 2024 Waec Model Questions Vol1 Agricultural Science examination.
In a fish pond, the catfish population N (in number of fish) follows the logistic growth equation dN/dt = r N (1 - N/K) with intrinsic growth rate r = 0.3 month⁻¹ and carrying capacity K = 2000 fish. Each month, after the natural growth, a fixed proportion h of the population is harvested. Determine the harvesting proportion h (as a percentage) that maximises the sustainable monthly yield, and compute that maximum yield (number of fish harvested per month).
