Study Notes
Biological Growth Function for Fish Stock
- Generally modeled using the logistic growth curve, which accounts for environmental limits.
- Growth is represented mathematically, showing how fish population changes over time based on factors like reproduction and resource availability.
Capture Fishery
- Refers to the sector of fishing that involves capturing wild fish from natural water bodies.
- Unlike aquaculture, which involves raising fish in controlled environments, capture fisheries depend on the health of wild fish populations and ecosystems.
Logistic Function Parameter 'r'
- Represents the intrinsic growth rate of the fish population.
- Indicates how fast the population can grow when resources are abundant and environmental conditions are favorable.
Logistic Function Parameter 'k'
- Denotes the carrying capacity of the environment.
- This is the maximum population size that the environment can sustain, taking into account limited resources such as food and habitat.
Context of X = k in Fishery Biology
- Indicates a state where the fish population has reached its maximum sustainable level.
- At this point, the growth rate slows down, and the population stabilizes, reflecting ecological balance.
