Gce Model Questions Vol1 2019 Agricultural Science Question 30
Practice objective / multiple choice question 30 from the 2019 Gce Model Questions Vol1 Agricultural Science examination.
A fishery manages a stock that follows the logistic growth model \(\frac{dB}{dt}=rB\left(1-\frac{B}{K}\right)-H\), where \(B\) is biomass (tonnes), \(r=0.4\) yr⁻¹, and carrying capacity \(K=5000\) t. The current biomass is \(B_{0}=2000\) t.\n(a) Calculate the maximum sustainable yield (MSY).\n(b) Determine the constant annual harvest \(H\) (in tonnes) that will result in a biomass of \(2300\) t after one year, and state whether this harvest is above, below, or equal to the MSY.
