Gce Model Questions Vol1 2020 Agricultural Science Question 16
Practice objective / multiple choice question 16 from the 2020 Gce Model Questions Vol1 Agricultural Science examination.
An inland fishery follows logistic growth with intrinsic rate (r = 0.5\ \text{yr}^{-1}\) and carrying capacity (K = 20\,000\) fish. The current constant annual harvest is (H_{0} = 2\,000\) fish. (a) Determine the equilibrium stock size \(N_{eq}\) under this harvest. (b) A management measure reduces the harvest by 20 % (so the new harvest is \(H_{1} = 0.8 H_{0}\)). Find the new equilibrium stock \(N'_{eq}\). (c) Is the new equilibrium at least 75 % of the carrying capacity? Answer "Yes" or "No".
