We found the opposite situation in Baltimore, Maryland where fish sales prices were lower than input costs due to higher winter energy costs. Approaches to minimizing heating for fish would be raising species that can survive at lower water temperatures and require less heating, implementing renewable sources of energy such as photovoltaic (although there are higher start-up costs), raising higher value species to enhance the market price, or move location to sites with warmer winters or a better insulated space. Many factors such as markets, production scale, and start-up and recurring input costs need to be carefully considered when planning aquaponics businesses to avoid pitfalls.
