Neco Model Questions Vol1 2019 Agricultural Science Question 22
Practice objective / multiple choice question 22 from the 2019 Neco Model Questions Vol1 Agricultural Science examination.
A fish population in a lake follows the logistic growth model \(\frac{dN}{dt}=rN\left(1-\frac{N}{K}\right)\) with intrinsic growth rate \(r=0.6\) per year and carrying capacity \(K=25\,000\) tonnes. The fishery harvests a constant amount \(H\) (tonnes per year). The government wishes to increase the harvest to a new constant \(H_{2}\) but requires that the equilibrium population under the new harvest be at least \(12\,000\) tonnes. Determine the maximum allowable harvest \(H_{2}\) (in tonnes per year) that satisfies this condition, and give the corresponding equilibrium population.
