The Center for Tropical and Subtropical Aquaculture (CTSA) funded a project of “Economic Analyses of Aquaponics Systems in Hawaii and Guam” and is pleased to release Aquaponics Decision Software, a commercial aquaponics spreadsheet modeling system. The purpose of this generalized spreadsheet modeling system is to provide a user-friendly tool that can be used by existing and potential aquaponics producers as an on-farm decision aid, and by extension and research personnel to identify key areas where operations can be improved in order to sustain the profitability of aquaponics production.
While backyard aquaponics has become more common in recent years as a way to supply fish and vegetables for household consumption, several commercial-scale aquaponics farms have started operations in Hawaii. The economics of these operations have been unclear to this point, thus the primary purpose of the nearly-completed CTSA project is to determine the economic feasibility ofcommercial aquaponics farming in Hawaii and Guam.
Led by project P.I. Dr. PingSun Leung, researchers first conducted comprehensive economic analysis of existing commercial farms in Hawaii and Guam. Based on that data, they calculated investment and operational cost and created a model case to investigate economic feasibility of the system. They then constructed a prototype generalized spreadsheet modeling system based off the simple spreadsheet used to conduct the primary analyses of aquaponics farms. Stakeholder input was obtained and utilized to refine the software, which is available for free download on the CTSA website (click here). Note: you must enable macros in order to use the spreadsheet
Results from the careful analyses of existing aquaponics farms in Hawaii conducted during the first part of this project indicate that commercial scale aquaponics can be economically feasible. Going forward, the spreadsheet can serve as a useful tool for farmers, extension and research personnel to maximize the productivity of aquaponics in the Pacific region.
