Here are a few key terms to better understand the process along with why we've found Aquaponics to be so beneficial.
Fish: Once fish are fed, they produce ammonia rich waste. Bacteria turns the ammonia into nitrates which is absorbed into the plants. When fish grow to market size, they can be sold, and replaced with new fish reared from eggs.
Water: Water pumped through the grow bed is filtered by the plants, and then returned to the fish tank ammonia free.
Plants: Typically suspended on floating raft platforms or planted into rock, plants absorb the nitrates as nutrients. They grow quickly in the nutrient rich water and can be eaten or sold in the marketplace.
Oxygen: Fish breathe in oxygen and breathe out carbon dioxide. Plants absorb the carbon, leaving oxygen rich water to return to the plants.
Bacteria: Naturally occurring bacteria converts the ammonia into nitrites and then into nitrates with new fish reared from eggs.
Why Aquaponics? In developing (or struggling) nations, momentarily supplying needs is a great thing, but there must be a point where they're working with a self sustaining system of food production that allows them a more consistent and constant channel of provision.
Hydroponics can often meet that need.
We’re finding this to be true and are inviting you to join us as we work towards global justice by giving entire villages access to tools they otherwise would have no way of gaining.
