Oyster FARM (Financial And Risk Model) Calculator

Risk in oyster farming, as in all agriculture and aquaculture production, is any event that a grower cannot control but affects the grower’s operation. However, various types of risk can be forecasted based on historical events and trends. A financial tool has been developed using these findings, which allows oyster growers to generate predictive costs and revenues for their farms and investment situation. This Calculator quantifies environmental and economic risks associated with oyster culture using damage reports, grower estimates, and historical data. Developed using Microsoft Excel 2018, the Calculator is compatible with previous Excel versions. First, growers enter their individual farm information over a 5-year planning period. Then, risks based on probabilities determined for four counties (Escambia, Franklin, Levy, Wakulla) on Florida’s west coast are applied to determine potential net income values. The Calculator allows oyster growers to better understand how risk affects profitability.

The Calculator was developed by Rusty Dame, a graduate student in the University of Florida/IFAS Food and Resource Economics Department, and Leslie Sturmer with UF/IFAS Extension. Rusty’s master’s thesis sought to determine how risk affects the profitability of oyster aquaculture on the west coast of Florida. Funding for this project was obtained from NOAA National Sea Grant through the Aquaculture Extension and Technology Transfer Program.
