IGA Systems Methodology

Why Consider IGA?

IGA facilitates clients by enabling them to grow nutritious, safe, locally grown, beyond organic food that can feed a family and/or community in half the time as current commercial agriculture.

  • Most plants grown aquaponically grow twice as fast; lettuce takes 29+ days to mature, instead of 60+ days in traditional farming.

  • IGA can design specialized systems to meet the customers’ desired spatial and productivity needs. IGA’s systems vary in size from small personal units to large commercial systems.


IGA’s System Advantage

A few details from one of our designs for commercial or community aquaponics systems is as follows.

Using a modular approach, we can provide the same highly refined technology for both small and large systems without having to go back to the drawing board, starting from scratch every time a client comes to us with a request for a system design. Our 5 tank module can be installed as a single unit producing 25,000 pounds of fish per year. By adding additional units in tandem, our modular system is capable of producing millions of pounds annually.


Our systems also use the most advanced bio-filtration, “bio contactor” technology in the industry. This new device is both energy efficient and features a unique design rotation and tank configuration.

A gravity flow from the tanks moves through the drum filter and then through the bio-filter. Not one pump is used, which reduces energy requirements and wear on the system.

To demonstrate the scalability and production capacity of a mid-sized community or business aquaponics system, IGA presents the following eight year expansion plan. This facility project example is designed to be 4 times larger in year 8 than year 1:

  • 625 sq. ft. of raft grow space increasing to 2500 sq. ft.
  • 272 sq. ft. of media bed space increasing to 1088 sq. ft.
  • 6 stock tanks increasing to 24 with a fish harvest every 4 weeks.
  • 2880 sq. ft. of initial green house space increasing to 11,520 sq. ft.
  • 625 heads of lettuce a week increasing to a yield of 2,500 heads per week
  • 46,000 lbs. of tomatoes, cucumbers and bell peppers annually, increasing to a yield of 260,755 lbs. per year.
  • 2,749 lbs. of Golden Tilapia annually increasing to a yield of 10,998 lbs. per year
