That cos' is the aquaponics?

The aquaponics is a combination of recirculation aquaculture and hydroponics. In aquaponica grow with the plants and fish in an integrated system. The waste of the fish provide a food source for plants that grow offend a natural filter for the water in which the fish live. This creates a sustainable ecosystem where both plants and fish can thrive. L 'aquaponics is the ideal answer to the problem of the fish farmers to have nutrient-rich waters and the needs of hydroponic farmers to have nutrient-rich water. Given the nature of aquaculture and hydroponics recycling (the two technologies are combined nell'acquaponica) find 2 main elements in all systems acquaponici:

    • The fish are bred in tanks
    • It is a system of cultivation without soil

The aquaponics is organic?

L 'aquaponics is a completely natural process that renders the operation of all the lakes, ponds, rivers and streams on earth. The only additional element in a acquaponico system is the fish food. The fish eat the food and excrete waste, which is converted (by beneficial bacteria) in a form that plants can use. In consuming these nutrients, plants help to purify water. You can not use herbicides, pesticides or other harsh chemicals in a acquaponico system, this will make the fish and plants healthy and safe to eat.

What are the benefits of cultivating with aquaponics?

The combination of aquaculture and hydroponics is quite new and the potential of 'dell'acquaponica use to cultivate high-quality food in the world is enormous. Here are some of the many benefits of food production aquaponics:

    • the aquaponics uses water rich in nutrients from aquaculture that would otherwise be a waste product, or would need to be filtered in a costly way
    • the aquaponics eliminates the cost and time required for mixing traditional hydroponic nutrients
    • the aquaponics provides a truly organic natural form of nutrients for plants
    • removing the soil in plant production, They erase all the diseases that arise from the ground
    • the aquaponics uses only a portion of the water that the traditional cultivation uses because the water is not wasted or consumed by weeds
    • nell'acquaponica, the plant spacing can be very intensive, allowing to grow more plants in a given space
    • with a high storage density in the fish tank, the plants will grow quickly and develop into a system acquaponico
    • in acquaponici systems you can not use pesticides or herbicides, This makes the end product more safe and healthy
    • If the weather allows, or if you are growing in a greenhouse, You can be grown all year round using a system acquaponico

What plants can I grow?

They can be grown to hundreds of species of plants.

At the beginning of research on aquaculture systems, They were made experiments to determine the efficiency of aquatic plants which consume the nutrients in aquaculture water, thus helping to purify water for fish in the system. As the research progressed, terrestrial plants have been tested and it has been demonstrated that these were an effective means of water purification for aquaculture and this water rich in nutrients almost ideal solution for a hydroponic plant growth. At the beginning were considered for the aquaponics lettuce, chives and other leafy crops but, more recently, commercial growers and researchers have had great success with tomatoes, cucumbers, pepperoni, meloni, flowers and many other crops.

What fish can breed?

"There are hundreds of species of fish that can be grown in aquaponics, among these are the sea bass, carp and goldfish. If you are planning a domestic or commercial food production, you should start by contacting the agency which oversees fish and waterways in your area to find out if there are any restrictions the fish that you can breed. Tilapia, a freshwater fish that grows fast and has a white meat and soda when filleted, It is commonly grown in aquaponics because it is very resistant and can tolerate a wide range of water quality conditions.

How many fish can I put in the aquarium?

It depends on the size of the tank and the type of filtration which has. In a system based on the fish tank, a good general rule is to fill the tank to 1″ (fish length) per gallon of water. In larger systems with adequate filtration, the commercial growers usually fill the tank to a maximum of 1/2 lb fish / gallon d 'water.

How many plants can I have a number of fish?

The number of plants that can grow is directly related to:

  • The number of fish
  • The size of the fish
  • The amount of food for fish added every day
Scientists at the University of the Virgin Islands have established that for every 60-100 grams of food for fish added daily, you can support 1 sq.m.. of plants in a raft aquaponica.

I earn with the aquaponics?

L 'aquaponics, like any business, It requires adequate investment in equipment, Proper design and excellent management skills and marketing. Furthermore, you need to be a bodybuilder expert in fish and plant grower. With these qualifications, an aquaponics farm can be very profitable. From the commercial point of view, the aquaponics is still in its infancy, but, as the technology develops and refines, It has the potential to be a fish culture method, very efficient plants and herbs and with the most efficient use of space. Incorporating aquaponics, growers in hydroponics can eliminate the cost and the work required by mixing a fertilizer solution and the commercial fish farmers may be able to drastically reduce the amount of filtration required in a recirculating fish culture. Although there is currently a limited number of commercial transactions acquaponiche, many people are expressing a strong interest in this intensive method of food production.

I found some old tanks, I can use them for fish tank?

Your aquariums and materials used for your system should be the plastic for food. This means that not seep chemicals in 'water in the system. You should not use tanks or containers that have had different content from foods or that are not recommended for fish or growing plants.

What should I feed the fish?

If your goal is an optimal growth rate and food production, you need to feed your fish with a specific food for the species. There are many producers of food for fish. You can search online sources or through local resources, such as grocery stores and suppliers. If you have a low-tech system and maximum production is not your goal, you can grow or make your own fish food. duckweed, Water lettuce and worms are often used to feed the tilapia.

How does it work?

The key to a successful acquaponico system are the beneficial bacteria that turn fish waste into nutrients used by the plant. more of 50% waste products from the fish is in the form of ammonia, secreted through the gills and urine. The rest of the waste, excreted as fecal matter, It undergoes a called mineralization process that occurs when the heterotrophic bacteria consume fish waste, decaying plant matter and food remains, converting all three into ammonia and other compounds. In amounts sufficient ammonia is toxic to fish and plants. Batteri nitrificanti, that naturally live in the soil, water and air, first convert ammonia to nitrite and then into nitrates that plants consume. In your system acquaponico nitrifying bacteria will thrive in the gravel in the fish tanks and in the culture medium in the growing bed. Plants readily absorb nitrates in the water and, to consume, They help to keep the safe water quality for the fish.

I need a greenhouse?

A greenhouse provides protection from environmental factors such as heat, the cold, the wind, the rain and the intrusion of insects. In most climates, a greenhouse is necessary. A greenhouse can also be useful in the tropics to protect crops from rain, wind and insects. The type of greenhouse and environmental control equipment varies widely depending on climate. There are growers aquaponics, however, systems that have to spend time at home, in a basement or garage. When they are indoors, must add artificial lighting for plants.

I can do it as a hobby or for a school project?

A hobby level, the aquaponics is spreading rapidly. An aquarium at home, with ornamental or food fish, It can be combined with a mini garden, by growing herbs, vegetables or flowers. A system created for hobby can serve as a food production system, depending on the size. Many backyard gardeners are building systems to cultivate hundreds of pounds of fish and all fresh vegetables, in which a family needs,it.
