Borgmann Aquaponik und Hydroponi offers advice, technology, technical knowledge and the conceptual design of the entire plant from a single source. This is a unique selling point of the company.

The change from traditional agriculture to aquaponics or hydroponics is a big step for the entrepreneur. It requires a rethink in many aspects and, not least, large investments. However, the costs for the conversion hardly exceed the price of a modern agricultural machine, and the system does not need any oil or have to be inspected by the DOT (Department Of Traffic).

Here, the company Borgmann Aquaponik Hydroponik offers a new possibility to transform the agricultural business into the twenty-first century. The EU already offers subsidies for this new technology, which makes conversion even more attractive for many interested parties.

The offer includes feasibility studies, advice on the technical implementation, the installation of the systems as well as training in their handling and operation.

Furthermore, we offer calculation of the operating costs, quantification of the risks as well as an amortisation planning for the evaluation of the economic viability on the basis of the investment volume in relation to the selected foodstuffs and the expected operating costs. We also provide services for the partial optimisation of existing or third-party plants.

The optimisation offer includes, among other things, the adjustment of nutrient mixtures, lighting optimisation in closed plants with consideration of the growth phase in artificial light.
Our services include the general takeover or just the technical planning of farm projects up to the construction management and commissioning of the plant. We also provide advice and support during operation.

Our special field of research is the adapted nutrient requirement depending on the growth phase of the respective plant. This requires a biochemical analysis of the nutrients consumed or required by the plant depending on its stage of development.

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.

Here is a first impression of what needs to be considered when choosing a system - this is just a simplified example to give you an idea.

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.
