Numbers
When sizing an aquaponics system, there are several key factors to consider in order to plan an efficient and sustainable system. Here are some important keywords and costs that describe technical aspects of sizing an aquaponic system:
System size and capacity
- Total area of the facility
- Number of fish tanks and plant population
- Total water and air volume
The capacity determines the amortization, or more precisely the break-even point - i.e. when and how much profit can be expected. Available capital, market needs, competition and, last but not least, legal requirements are crucial here. To give you an idea, here are a few numbers:
To produce around 2,700 kg (all year round) of tilapia with a yield of around 180 kg/every 4 weeks, you need a system that costs around €100,000 . The current (2024-05) price of tilapia per kilogram may vary depending on source and availability. According to the search results, you can see that the price for tilapia fillet without skin and bag 800g, piece 140-200g, individually removable, is between €15.99 and €29.99 per kilogram.
At €15 per kilo, that would be around €2,700 per month in income . A general answer to personnel and operating costs becomes much more difficult. Here you will not be able to get realistic figures without advice, for example from us. The question here is complex.
Below are some keywords to show the extent of the complexity
Water quality and management
- pH value of the water
- Ammonia, nitrite and nitrate concentrations
- Temperature control and management
- Oxygen content in the water
- Filtration systems (mechanical and biological)
Fish stock and species
- Selection of fish species based on environmental factors and market demand
- Density and size of fish per container
- Feeding regime and feed quality
Plant selection and cultivation:
- Selection of plant species based on growing conditions and market demand
- Root space and planting density in the beds
- Lighting and shading for plant growth
Hydroponic components:
- Type of hydroponics (e.g., NFT, ebb-flow, drip irrigation)
- Substrate choice and availability
- Nutrient solution composition and management
Energy and resource efficiency:
- Use of renewable energies (e.g., solar energy, wind power)
- Water recovery and recycling
- Efficient use of space, light and heat
Regulation and monitoring:
- Automation of watering, feeding and ventilation
- Monitoring systems for water parameters and environmental conditions
- Alarms and emergency measures in case of deviations
Economic aspects:
- Cost-benefit analysis for the construction and operation of the plant
- Profitability and financial forecasts
- Market analysis and sales opportunities for fish and vegetables
Regulatory requirements:
- Compliance with environmental regulations and laws
- Permits and licenses for operating an aquaponics system
- Safety and hygiene regulations for food production
Sizing an aquaponics system requires careful planning and consideration of all of the above factors to ensure a successful and sustainable system. We offer professional advice with experts in the fields of aquaculture, hydroponics, engineering and agricultural sciences . Contact us.
