Free Report - Aquaponics

by Sagar Koirala | 16-10-2021 20:21 recommendations 0

 According to a joint report from the Food And Agriculture Organization and Smart-Fish, aquaponics is the cultivation of plants and aquatic animals in a recirculating environment. Aquaponics is a cooperation between plants and fish and the term originates from the two words aquaculture (the growing of fish in a closed environment) and hydroponics (the growing of plants usually in a soil-less environment). Aquaponic systems come in various sizes from small indoor units to large commercial units. and they can be either freshwater systems or contain salt or brackish water.

There are two main types of aquaculture—marine and freshwater. Moreover, the FAO also describes aquaculture as the captive rearing and production of fish and other aquatic animal and plant species under controlled conditions. Many aquatic species have been cultured, especially fish, crustaceans and mollusks and aquatic plants and algae. Aquaculture production methods have been developed in various regions of the planet, and have thus been adjusted to the distinct environmental and climatic conditions in different regions. The four major categories of aquaculture include open water systems (e.g.cages, longlines), pond culture, flow-through raceways, and recirculating aquaculture systems (RAS).

Fish eat the food and excrete waste, which is converted by beneficial bacteria to nutrients that the plants can use. In consuming these nutrients plants help to purify the water. Aquaponics integrates aquaculture and hydroponics into one production system. Aquaponics relies on the food introduced for fish, which works as the system’s input. As fish eat this food and process it, they transform it into urine and fecal matter, both rich in ammonia, which in sufficient quantities can be toxic to plants and fish. Afterward, the water (now ammonia-rich) flows, together with un-eaten food and decaying plant matter, from the fish tank into a biofilter. Afterward, inside this biofilter, bacteria break everything down into organic nutrient solutions (nitrogen-rich) for growing vegetables.

    Hello Sagar, this is your mentor Hannah. Sorry for the late comment!

    The term aquaponics is new to me, so while I was reading it was able to learn many things!
    I guess this shows the circulation of elements and how living creatures compose whole nature.
    So with the plants and aquatic animals they can survive just by themselves, right?

    Thank you for your great article and please keep up with your wonderful work :) Happy new year!

    Sincerly,
    Hannah

    Hello Sagar, this is your mentor Joon.

    Good article with such an interesting topic. I wonder how marine aquaponics
    work. Can salt water be absorbed to plants? It would be interesting to find out.
    I guess the combination of aquaculture and hydroponics can be a sustainable
    and effective way if the investment cost is low. It is a good cycle between animal
    and plant providing beneficial materials for both. Hope more studies are made
    and different approaches are taken.

    Well read your article. I hope you are doing well.

    Yours,

    Joon
