Practice objective / multiple choice question 3 from the 2025 Gce Model Questions Vol1 Agricultural Science examination.
A fish pond is initially stocked with 10 000 fish. The population follows logistic growth with intrinsic rate r = 0.4\,yr^{-1} and carrying capacity K = 50\,000 fish. Each year, 5 % of the fish die from disease, and a constant number H of fish are harvested. The manager requires that the population never falls below 8 000 fish.
