Lid as a plant bed

To obtain the two required parts, the upper part of the water tank must be cut off with a jigsaw or similar. A height of about 25 centimetres is sufficient for hydroponics (e.g. expanded clay). Ideally, the downward-facing filling opening should be provided with a cover filter so that the substrate is not washed out. After completion, a suitable pipe runs from there back to the lower tank or into other beds or containers, where the circulation pump is located.

A stand that is used separately offers the plant bed an elevated position with the comfort of a raised bed, which also promotes water drainage. Another alternative is to install a suction fitting for an external pump.

Raise fish in the container

The heart of the DIY aquaponics is the IBC container, which as a standard version still holds a good 1000 litres for the irrigation technology including fish farming. The stopcock can be replaced with a hose adapter that ensures water return.

Threaded and clamp fittings round off the portfolio, which makes it possible to install additional inlets and outlets. Here, too, the installation of filters ensures the necessary water quality and retains coarser particles.

The right fish

The type of fish has a significant influence on the later yield. Tilapia, which belong to the cichlid family, are suitable for rearing. The colloquial name "tomato fish" emerged from research, as it has ideal prerequisites for unproblematic breeding in an aquaponic system. Tilapia are robust and fully grown after a short time. They spawn comparatively often and thus secure their own stock. In addition, they do not need any separately fed feed, because vegetable residues are sufficient for their food intake.

Alternatively, African predatory catfish are also suitable for breeding in IBC containers. Due to their high content of protein and omega-3 fatty acids, they are suitable for use as food fish, just like tomato fish. The biggest challenge in fish farming is the water temperature, as both species are warm-water fish.

Kifuniko kama kitanda cha mmea

Ili kupata sehemu mbili zinazohitajika, sehemu ya juu ya tank ya maji lazima ikatwe na jigsaw au sawa. Urefu wa takriban sentimita 25 unatosha kwa hidroponics (k.m. udongo uliopanuliwa). Kwa hakika, ufunguzi wa kujaza unaoelekea chini unapaswa kutolewa na chujio cha kifuniko ili substrate isioshwe. Baada ya kukamilika, bomba linalofaa linatoka huko nyuma kwenye tank ya chini au kwenye vitanda vingine au vyombo, ambapo pampu ya mzunguko iko.

Msimamo ambao hutumiwa tofauti hutoa kitanda cha mmea nafasi ya juu na faraja ya kitanda kilichoinuliwa; ambayo pia inakuza mifereji ya maji. Mbadala mwingine ni kufunga kifaa cha kufyonza kwa pampu ya nje.

Panda samaki kwenye chombo

Moyo wa aquaponics ya DIY ni chombo cha IBC, ambacho kama toleo la kawaida bado kinashikilia lita 1000 nzuri kwa teknolojia ya umwagiliaji ikiwa ni pamoja na ufugaji wa samaki. Stopcock inaweza kubadilishwa na adapta ya hose ambayo inahakikisha kurudi kwa maji.

Vipimo vilivyo na nyuzi na clamp huzunguka kwingineko, ambayo inafanya uwezekano wa kusakinisha viingilio na maduka ya ziada. Hapa, pia, ufungaji wa filters huhakikisha ubora wa maji muhimu na huhifadhi chembe za coarser.

Samaki wa kulia

Aina ya samaki ina ushawishi mkubwa juu ya mavuno ya baadaye. Tilapia, ambayo ni ya familia ya cichlid, inafaa kwa ufugaji. Jina la kawaida "samaki wa nyanya" liliibuka kutokana na utafiti, kwa kuwa lina sharti bora la kuzaliana bila shida katika mfumo wa aquaponic. Tilapia ni imara na hukua kikamilifu baada ya muda mfupi. Wao huzaa mara nyingi kwa kulinganisha na hivyo huhifadhi hifadhi yao wenyewe. Kwa kuongeza, hawana haja ya kulisha tofauti tofauti, kwa sababu mabaki ya mboga yanatosha kwa ulaji wao wa chakula.

Vinginevyo, kambare wa Kiafrika wawindaji pia wanafaa kwa kuzaliana katika vyombo vya IBC. Kwa sababu ya kiwango cha juu cha protini na asidi ya mafuta ya omega-3, zinafaa kutumika kama samaki wa chakula, kama samaki wa nyanya. Changamoto kubwa katika ufugaji wa samaki ni joto la maji, kwani aina zote mbili ni samaki wa maji ya joto.
