Neco Model Questions Vol1 2020 Agricultural Science Question 44
Practice objective / multiple choice question 44 from the 2020 Neco Model Questions Vol1 Agricultural Science examination.
A fish population in a lake follows the logistic growth model \(\frac{dP}{dt}=rP\left(1-\frac{P}{K}\right)-H\), where \(P\) is the biomass (tonnes), \(r=0.4\ \text{yr}^{-1}\) is the intrinsic growth rate, \(K=5000\ \text{t}\) is the carrying capacity and \(H\) is a constant annual harvest (tonnes yr\(^{-1}\)). Determine the harvest level \(H\) that gives the maximum sustainable yield (MSY) and state the equilibrium population size at this harvest level.
