Where can money be invested today that will give the investor a reasonable rate of return and more importantly assure a safe investment that will be long lasting and be selling product into a growing and insatiable market? Go through the list of all of the possibilities you can think of, and then, add in these additional benefits to the equation:



  • Produces food on a year round basis
  • Can be solar powered
  • Can use recycled water
  • Employs local semi-skilled labor (women, men, young and old)
  • Enhances the value of the property and surrounding property
  • Is non-polluting
  • Produces organic food and requires 90% to 95% less water than in-ground growing
  • Can be installed nearly anywhere in the world
  • Produces an organic fertilizer that can be used on any crop or plants 

How are we doing? Interested enough yet to ask, “What’s the catch?” or do you need more benefits?

Let’s add in: 

  • Unlimited expansion in a designated territory
  • Small annual renewal fee
  • Constant updates to the technology
  • Engineers available to be on site to help with the initial installation
  • Consulting help at a very reasonable rate 

If you are NOT interest yet, stop reading. This opportunity is for first adaptors who are sophisticated investors and willing to help the industry expand into new territories. 

CCRES AQUAPONICS (large aquaponics systems combining aquaculture – the culture of fish, with hydroponics – using only water and water based nutrients to raise plants) is over 4,700 years old and is not new technology. What CCRES AQUAPONICS has done is to bring the technology into the 21st Century through the use of simple modern equipment and careful design. The commercially designed CCRES AQUAPONICS are modular, simply constructed from locally obtained materials, easy to operate and very nearly failure proof. The systems can lose power for over twelve hours and have NO adverse effects on the plants or fish.  

CCRES AQUAPONICS Greenhouse was constructed in the summer of 2011.

Intensive aquaculture production was integrated with intensive greenhouse hydroponic vegetable production.

 Environmental monitoring and control systems allow the grower to optimize the environmental parameters for maximizing crop yields. Water chemistry is maintained and nutrients are supplemented to meet the target crops nutritional demands. Organic plant cultivars are grown using biologically processed fish effluents and  CCRES AQUAPONICS listed organic nutrient supplements. Fish are grown and harvested on a monthly basis. Romaine and butter head lettuce, red and green oak leaf lettuce, microgreens, basil, peppers and cucumbers are also grown in the system. The produce and fish have been marketed to high end restaurants and farmers markets.

Fish are reared from egg to a harvest size . Production is staggered for continuous harvest on a monthly basis.

The filtration system removes large particulate waste and biologically processes the dissolved nutrients to a non-toxic form for the fish, and into a more readily available form for the plants to assimilate. The water chemistry is maintained for optimal growth of the fish. After the water passes through the filtration system it then flows to the respective plant greenhouse bay where the water chemistry is tailored to meet the target crops nutritional requirements.

There are two plant production bays with individual environmental controls. The environmental parameters for each bay are set to meet the plants optimal conditions for growth. Nutrient supplements are injected into the water prior to entering the hydroponic plant bays. The plants assimilate the nutrients in the system and the water is returned to the fish.

This system uses 1-3% of the system water volume per week (depending on season). The excreted nutrients from the fish are used as a natural fertilizer for the hydroponic plants. Research studies have shown that growth and quality of the plants in the aquaponics system is equal to that in hydroponic systems when the proper filtration processes and nutrient supplements are applied. CCRES AQUAPONICS market studies have determined that the produce can be marketed to high end restaurants, farmer’s markets and grocery stores.


 If you have read this far the next question is: How much is required to be an investor for commercial aquaponics systems?
