Study Notes
Bio-Economic Model of Fishery
- The function F(X) represents the growth rate of the fish population within the bio-economic model.
- It quantifies how fish populations change over time based on various factors including reproduction and fishery practices.
Capture Fishery
- 'Capture fishery' refers to the practice of harvesting wild fish from their natural habitats.
- This contrasts with aquaculture, where fish are cultivated in controlled environments.
Parameter 'r' in the Logistic Function
- The parameter 'r' indicates the intrinsic growth rate of the fish population.
- A higher 'r' suggests a faster growth rate under ideal environmental conditions.
Parameter 'k' in the Logistic Function
- The parameter 'k' represents the carrying capacity of the fish population, which is the maximum population size that the environment can sustain.
- It accounts for limitations such as food availability and habitat space.
Maximum Sustainable Yield (MSY)
- The flow of harvestable fish reaches the maximum sustainable yield (MSY) at the point where the growth of the fish population equals the rate of harvesting.
- This optimizes fish yields while ensuring long-term sustainability of the fish stock, as shown in Figure 13a.
