Aquaponics involves the simultaneous production of plants and fish and it is increasingly being used with a self-consumption purpose. However, there are uncertainties and little information about the economic sustainability of small-scale self-managed aquaponic systems. The objective of this study was to obtain economic information about these systems, including the level of commoditization of food production as a measure of their autonomy. For this purpose, two small-scale aquaponic systems (SAS) based on FAO models were self-constructed using cheap and easy-to-obtain materials and monitored for a year. A total of 62 kg of tilapia and 352 kg of 22 different vegetables and fruits were produced, with an average net agricultural added value of 151.3 €. Results showed positive accounting profit but negative economic profit when labor costs were included. The degree of commoditization was around 44%, which allows a certain autonomy, thanks to the use of family labor force.

La Noria social innovation center has promoted the first aquaponics system in the province of Malaga, a technique that combines aquaculture and hydroponics for the production of fish and plants in the same cycle. Producers can grow different varieties of fruits and vegetables in this system, such as…

Aquaponic facilities allow the joint production of fish and plants in a reduced space. This hydroponic technique, combined with vertical farming, is not well studied. The main objective of a recent work was to compare basil production between horizontal and vertical decoupled aquaponic systems and assess…

Aquaponic facilities allow the joint production of fish and plants in a reduced space. This hydroponic technique, combined with vertical farming, is not well studied. The main objective of this work was to compare basil production between horizontal and vertical decoupled aquaponic systems and assess the utilization of supplemental lighting in a greenhouse environment. Six independent vertical racks were arranged with hydroponic trays at three heights. Three racks were affixed with LED lighting on the lowest levels and three with supplemental lighting on the intermediate level. Immediately adjacent to the vertical systems, two independent horizontal systems containing three trays were constructed to compare basil production. After 35 days of growth post transplanting, the total production per tray and weight, height, number of leaves, and nodes of 20 selected plants per tray were determined. Records of the intensity of illumination photosynthetic photon flux density (PPFD)) were recorded at dawn (8:00), noon (12:00), and dusk (18:00) at randomly predetermined positions associated with the 20 selected plants per tray. The total basil production in the experiment was 58.79 kg, with an average production per unit area of 2.43 and 0.94 kg m−2 for vertical and horizontal systems, respectively. Productivity per unit area in the vertical systems was 160% greater than in horizontal systems.

Aerobic mineralization is very similar to Aerated Compost Tea (ACT) or Actively Aerated Compost Tea (AACT) and is one of the easiest ways to grow more plants using less fish in aquaponic or aquaculture systems.  You may already have heard of ACT or ACCT being used in the soil systems thanks to the hard work…

Multivac identifies controlled environment ag as key market

Controlled-environment produce packaging has become a new market focus for Multivac Inc., a German equipment manufacturer with U.S. headquarters in Kansas City, MO.

Multivac sells packaging equipment and materials to create the ideal produce packages. It specializes in food packaging and in recent years, Cem Yildirim, national sales manager for produce, has aggressively built a presence in the fruit and vegetable market segment.

The firm’s German-engineered technology applies a variety of options in forming and sealing equipment to create highly advanced modified atmosphere consumer packages.

Yildirim cites many advantages for controlled environment agriculture — "CEA" — to use Multivac technology. These operations produce and sell product 12 months a year through hot houses, hydroponics, and aquaponics.

Yildirim notes that even in the idyllic environment of some California growing areas, it is generally rare for a farm to produce and pack every day of the year. “When you’re harvesting and packing every day, it’s more like a dairy operation. The product just keeps coming and your packaging operation must be able to keep up. Every day there is more to harvest.”

Thus, it becomes highly cost-effective to invest in top-level, efficient packaging technology.
