Much thought has been given to global food security, water and nutrient expenditure. Hydroponics is a technique that has been around for some time and is relatively well accepted in both developed and undeveloped countries in general. Aquaponics, being a variant of hydroponics, in which the nutrients needed for cultivation come from the fish breeding tank, which excrete ammonia directly into the water. The present work has as its main proposal to present an alternative to traditional aquaponics, so that, instead of using fish as a breeding and source of nutrients, use the aquatic fern: Azolla caroliniana, due to its characteristic of assimilation of atmospheric nitrogen in the water , ease of propagation and maintenance. In addition, the vegetable has nutritional properties for both animal and human consumption, and can be used both environmentally and economically.
