02 · The concept

Fish, bacteria, plants —
unbeatable together

Aquaponics is not just a new marketing term for hydroponics. It is a biological system that turns your fish’s waste into fertiliser for your vegetables — fully automatically, with no artificial fertiliser and no wastewater.

01

Fish produce ammonia

Fish excrete ammonia through their gills and urine — the natural fuel of the system. Species-appropriate husbandry, with no need for antibiotics.

02

Bacteria convert it

Nitrosomonas bacteria oxidise ammonia into nitrite, and Nitrobacter converts it further into nitrate that plants can absorb — around the clock, without any effort on your part.

03

Plants take up nutrients

Vegetables and herbs grow up to 50 % faster in the nutrient-rich water than in soil – and filter your fish’s water as they do.

04

Water flows back

Clean, oxygen-rich water returns to the fish — 95 % recycled, with no chemicals, no wastewater and no ongoing water costs.

03 · Your options

More culinary possibilities
for your restaurant

With PROAquaponik, you add products to your restaurant that can be produced right where you are: fish, herbs and vegetables from one shared cycle. In aquaponics, fish and plants use the same water: the plants absorb the nutrients from the fish farming, and the cleaned water flows back to the fish.

Fish for your kitchen

Fresh fish from your own system can become part of your menu, your specials and your own culinary line.

Herbs & vegetables

Herbs, salad greens and vegetables grow where they will later be used – with short distances and traceable origin.

New dishes & specials

Your own production creates room for seasonal menus, special fish dishes, tastings and changing offers.

A story for your guests

Your guests don’t just enjoy the product on the plate – they can see for themselves how fish and plants are connected in one cycle.

Your own specialities

Develop products and dishes that suit your kitchen and give your restaurant its own culinary signature.

Production you can experience

A production system becomes part of your dining experience – visible, easy to understand and directly connected to your kitchen.

04 · Shop to Shop

Your products can
reach other kitchens, too.

PROAquaponik doesn’t just open up new possibilities for your own kitchen. You can also share, exchange or pass on selected products to other hospitality businesses – Shop to Shop.

03 · The build process

How your system takes shape — step by step

On average, it takes 12 to 16 weeks from the first site visit to the first harvest. At every stage you know what happens next, who is responsible and what is needed from you.

Week1–2
1

Site analysis

We visit your farm and assess the available space, power supply and frost exposure. This gives a realistic picture: what is possible on your land, and at what scale is it worth getting started?

On site · approx. 1 day
Week3–4
2

Individual system planning / design

Together we decide on the fish species, crops, tank size and budget. You receive a detailed construction plan including a parts list — the basis for your permit.

Planned together with you
Week4–8
3

Preliminary meeting with sales and authorities

We agree the design with you and the responsible authority before moving on to detailed planning — so there are no surprises later in the approval process.

Meeting on site or online
Week8–10
4

Adjusting the plans to official requirements

We incorporate any conditions or feedback from the authority directly into the plans, so that nothing stands in the way of a smooth approval.

Revised by our planning team
Week10–14
5

Construction phase

Tanks, technology and grow beds are built on your farm — depending on the model you choose, either by yourself using our construction manual or with support from our partner team.

Self-build or assisted construction
Week14–16
6

Training and instruction before launch

Hands-on training for you and your team: feeding, water values, maintenance, harvesting. You take over the system with confidence, not with open questions.

1–2 training days on the farm
7

Launch

Initial fish stocking, first planting — your system goes into operation.

The big moment
8

Start-up phase, ongoing operation and support

Over 4 to 6 weeks the system builds up its bacterial culture — we support you closely, remotely as well. After that, the system is in your hands: you take care of maintenance yourself, and if you have questions you can reach our team by phone.

Support as needed, no tie-in contract
04 · Benefits

What aquaponics changes for your farm

Measurable benefits that directly affect costs, yield and market position — not in a glossy brochure, but in your farm accounts.

Low investment costs

Cost-optimised plans and self-build know-how let you get started with far less capital than a conventional new build.

Low operating costs

The system is biologically self-regulating. No fertiliser, no pesticides, hardly any water costs — running expenses fall for good.

Double yield, same space

Fish and vegetables from one system at the same time. Two sources of income — without buying more land or duplicating infrastructure.

Able to deliver 365 days a year

No seasonal gaps, no weather risk. Year-round availability — independent of imports and price fluctuations.

95 % less water use

The closed loop recycles almost all of the water. A clear cost advantage in dry regions or where water prices are high.

Everything from one source

From the first idea to the ongoing harvest: advice, planning, financing, construction and training — all from a single source.

Maintenance in your own hands

If you understand the system, you don’t need an expensive maintenance contract. Running it yourself reduces your dependence for good.

Start small, scale big

From entry-level system to commercial plant — any size is possible, step by step, without investing everything up front.

Premium positioning

Regional production and complete traceability: aquaponic products command premium prices because origin matters.

80 % less CO₂

No wastewater, no surplus, short transport routes. A strong argument for funding bodies, retailers and consumers.

Knowledge instead of dependence

Courses and support give you the skills you need. Independent in the long term — without relying on permanent outside help.

Make your own fish products

Your catfish becomes refined products such as ham or burger patties — extra value created right on your farm instead of selling raw product at market prices.

05 · For the technically minded

What really happens in the system

No business takes on a system it doesn’t understand. That’s why we explain the biology and technology openly — concisely, and without needing a chemistry degree.

Microbiology

Nitrification: the silent force

Nitrosomonas bacteria oxidise ammonia (NH₃) into nitrite (NO₂⁻). Nitrobacter converts this further into nitrate (NO₃⁻) — the primary plant nutrient. Both processes run fully automatically, around the clock.

Water chemistry

pH 6.8–7.2: the compromise

Fish prefer a slightly higher pH, plants a slightly lower one. The shared optimum of 6.8–7.2 keeps all three system partners healthy at the same time — a stable range that is easy to control.

Plant growth

Roots directly in nutrient water

With the NFT or DWC method, the roots hang directly in the nutrient solution. With no soil resistance and nutrients immediately available, plants grow up to 50 % faster than in open fields.

Oxygen supply — what matters
Fish and bacteria compete for oxygen. Aeration that keeps dissolved oxygen above 6 mg/L keeps both system partners healthy and productive in the long term.
Temperature — the choice of fish defines the system
Trout thrive at 14–18 °C, tilapia at 22–28 °C. Water temperature affects growth, bacterial activity and energy demand alike — we choose the fish species to suit your location and energy concept.
Start-up phase — 4 to 6 weeks to stability
New systems need time to build up stable bacterial colonies. Managing this phase properly is crucial for long-term success — and this is exactly where we support you most closely (see build process, step 8).
07 · Aquaponics simply explained

A cycle that connects
fish and plants.

You don’t need to be a technical expert to understand the principle: fish and plants share the same water. The fish provide nutrients, and the plants absorb them and help to clean the water again.

01

Fish produce nutrients

Keeping fish creates natural nutrients in the water.

02

Plants absorb them

Herbs, salad greens and vegetables use these nutrients to grow.

03

The water is cleaned

The plants take nutrients out of the water and so help to keep the cycle clean.

04

The water flows back

The cleaned water returns to the fish – and the cycle starts all over again.

What matters for you as a restaurateur:

One cycle creates several culinary possibilities – fish, herbs and vegetables can go straight into your kitchen, into new products, into partnerships or into special guest experiences.
