So, let’s talk about how green aquaponics is. Aquaponics energy usage is from 70% to 92% less than a conventional or organic farm which use fuel and/or petrochemical-intensive fertilizers. All energy used is electrical, so alternate energy systems such as solar, wind, and hydroelectric can be used to power an aquaponic farm 100%. This alternate energy can be produced locally instead of being shipped in from oil-refining countries, which may be great distances away from the end-user.
Freshwater fish are the most common aquatic animal raised using aquaponics, although freshwater crayfish and prawns are also sometimes used. In practice, tilapia are the most popular fish for home and commercial projects that are intended to raise edible fish, although barramundi, silver perch, eel-tailed catfish or tandanus catfish, jade perch and Murray cod are also used. For temperate climates when there isn’t ability or desire to maintain water temperature, bluegill and catfish are suitable fish species for home systems. Koi and goldfish may also be used, if the fish in the system need not be edible.

As in all aquaculture based systems, stock feed usually consists of fish meal derived from lower-value species. Ongoing depletion of wild fish stocks makes this practice unsustainable. Organic fish feeds may prove to be a viable alternative that relieves this concern. Other alternatives include growing duckweed with an aquaponics system that feeds the same fish grown on the system, excess worms grown from vermiculture composting, using prepared kitchen scraps, as well as growing black soldier fly larvae to feed to the fish using composting grub growers.
The Garden Pool was a large run-down pool that is now a backyard closed-loop food production system using aquaponics and is powered by solar energy. The GP was designed to feed a family of four with organic eggs, milk, fruit, veggies, herbs, and fish 365 days a year while using 90% less water than conventional farming methods. We are a non-profit organization to innovate, teach, and help others use more sustainable ways to grow food.
Another huge benefit of aquaponic growing is that it grows 100% chemical free, all natural produce. If any chemical or synthetic pesticides, herbicides, or fertilizers are used, the fish could die, effectively killing your system generator! There is no question that aquaponically grown food is chem free as it cannot be cheated. Even most approved organic pesticides could kill the fish.
Hopefully this helps provide some info to build your own system, and to feed your own family good food pesticide free.
