What is Aquaponics?

An integration of two systems:Hydroponics and Aquaculture

The process of growing food in an inert medium by controlling and adding nutrients but without soil

The cultivation of aquatic animals or plants for food.

History

The development of modern aquaponics:

In a modern context, Aquaponics emerged from the aquaculture industry as fish farmers were exploring methods of raising fish while trying to decrease their dependence on the land, water and other resources.


History

The term aquaponics is often attributed to the various works of the New Alchemy Institute and the works of Dr. Mark McMurtry at the North Carolina State University.

In 1969, John and Nancy Todd and William McLarney founded the New Alchemy Institute. The culmination of their efforts was the construction of a prototype Bioshelter, the “Ark”.

Why Aquaponics ?

(source: Pattillo and James, 2014 )

Advantages

• Reduced labour

• Nutrient management/effluent mitigation

• Plan grow 2x as fast

• Year round production possible

• 75% smaller footprint: Less space required per plant

• Prolonger individual plant life

• 90% Lees water consumption

• Soil pathogens eliminated

• Plants can be grown at desired height

• No weeding

Souces: Aquaponics – Advantages & Disadvantages. Online: http://wallyfarm.com/?page_id=521Sultana, R (2012) Aquaponics

Disadvantages

• Higher Initital Cost over Raised Beds and Hydroponics

• To fill up water tanks

• To build the system (Greenhouse, pumps etc.)

• Climate control & Lighting

• Government regulation of “fish raising”

• Competitive market prices

Why Vertical Aquaponics ?

Better use of space

Greater design possibilities

OUR OBJECTIVES

GENERAL :• Assesment of a vertical aquaponics system for

ornamental purposes

SPECIFICS:• Evaluate water quality and the development of fish

population in an aquarium using a Living wall as filter system, comparing it with an aquarium with a commercial filter system

• Growth and ornamental value assessment in an aquaponic living wall system.

CONCLUSIONS

1. Vegetation had good development in all cases

2. The main parameters of water quality, with the exception of pH, were maintained within acceptable ranges in both systems

3. The evolution of the fish population was slightly better in the aquarium control. different species were dominant in each of the systems.

4. In the aquarium with living wall only one specie (Xiphophorushelleri) presented an effective reproduction, while in the aquarium control there was more diversity in reproduction (3 species)

Our Future research…

Bigger LWs

More complex designs (integration with ponds)

Combining with edible fishes and horticultural

plants production
