Learning Machinations: Sustainable Systems V2
About this model
Fisheries: https://youtu.be/HMmChiLZZHg?t=1427
This diagram models a simplified fishery management system that illustrates the dynamics between fish population growth, fishing fleets, and economic calculations of yield, gross profit, expenses, and net profit. It is grounded on concepts such as carrying capacity, maximum sustainable yield, and the intrinsic growth rate of the fish population. The system begins with an initial fish population and employs various rates and formulas to simulate how the fish stock changes over time, influenced by fishing activities represented by the boat fleet. It calculates yield based on the fish stock and the efficiency of the boat fleet, which also experiences decay over time, representing the wear and tear of fishing vessels.
The economic facet is detailed through the calculation of gross profit from fish sales, with taxes and expenses deducted to arrive at the net profit. Registers are used to dynamically adjust factors such as the intrinsic growth rate of the fish population, carrying capacity, and a performance factor that might represent advancements in fishing technology or methods. The system also incorporates the concept of fishing quotas, allowing for a comparison of scenarios with and without regulatory measures in place. This diagram serves as a tool for understanding the balance between ecological sustainability and economic viability in fishery management.
