Neco 2017 Agricultural Science Question 42
Practice objective / multiple choice question 42 from the 2017 Neco Agricultural Science examination.
An isolated lake has a carrying capacity of \(K = 150{,}000\) fish. The current population is \(N_0 = 70{,}000\) and the intrinsic growth rate is \(r = 0.5\) per year. A fisheries manager can stock \(S = 4{,}000\) fish each year and wishes to allow a constant annual harvest \(H\) (fish per year). The population follows the discrete logistic model \(N_{t+1}= N_t + r N_t\!\left(1-\frac{N_t}{K}\right) + S - H\). Find the greatest integer value of \(H\) that guarantees the population after three years (\(N_3\)) is at least \(90{,}000\) fish.
