Aquaponic Production

This course provides sound, broad based training for commercial growers and amateur enthusiasts of this new food production system.

Aquaponics is the integration of hydroponics with aquaculture technologies and is a highly productive food system with regards to water use efficiency.

  • Hydroponics is the horticultural process of growing plants in mediums other than soil.
    Aquaculture is the culture of aquatic organisms (such as fish and crustaceans) for commercial purposes under controlled or partly controlled conditions.

Aquaponics is an intensive way of farming that can be conducted anywhere. It is a working model of sustainable food production wherein plant and animal agriculture are integrated and recycling of nutrients and water filtration are linked.

  • It can produce a great deal more food products per unit of area than more traditional forms of farming.
  • It diversifies the income for a grower, making them more resilient to fluctuations in income (eg. when vegetables are in less demand, fish might be in higher demand. If fish profits drop, vegetable profits may increase).
  • It can be viable on any scale. Small scale set ups in small home garden can provide for the needs of a single family; medium size operations on less than a quarter acre can be a viable small business, large scale operations on many acres, even hundreds of acres can also be viable
  • It can allow food to be produced closer to the end user in areas otherwise unsuited to farming (eg. in a desert, city, etc). This reduces food miles and expenditure of fuel on food transport and in turn increases freshness of food arriving at market.
  • It can be more efficient use of water where water resources are limited
  • It can be environmentally friendly, containing and reusing waste, rather than returning it to the environment, and causing pollution.

Like everything else, aquaponic production has both advantages and disadvantages. The scale of operation is not important; people practice small scale aquaponics in their home garden, while others operate large scale commercial aquaponic farms.

The course covers all aspects of the Aquaponics or "smart farming". Producers need to prepare well and become properly informed before risking the investment in money and time needed to achieve success. This course is a great starting point.
