I-Aquaculture, noma ukulima izinhlanzi ngomqondo omncane - enye yezinhlobo zezolimo ezindala. Kepha maqondana nokuthuthukiswa kwesikhala, akukhunjulwa kaningi, yize amathemba okuthuthuka kwalobu buchwepheshe ezimweni zangemva kokungemthetho kungokomfingo kakhulu. Ngaphansi ekusebenzeni kahle kokukhiqizwa kwezinhlanzi ezidliwayo, noma yiziphi ezinye izinhlobo zezilwane zasepulazini zithola, futhi kuphela izinkukhu kuphela ezingafaniswa nazo. Uma ungacabangi okuqukethwe kwezinto ezidingekayo ze-trace, ama-amino acid, ama-fatty acid namavithamini enyameni, ngoba kulokhu kulahlekelwa izinyoni.
Ngokwemvelo, ukuzalaniswa kwezinhlanzi kuzodinga ukwakhiwa kobuchwepheshe obusha kanye namaqhinga ahlukahlukene ukuhlinzeka izilwane ngemvelo efanelekile - njengoba nje zidinga amanzi amaningi. Kepha akekho onikeza ama-aquariums emkhathini. Iphrojekthi ye-European Space Agency Lunar Hatch isho ukulethwa enyangeni ye-caviar evundisiwe. Ama-cosmonauts ayobanjwa ngamanzi, azothola amakoloni ama-lunar avela eqhweni lendawo. Udaba lokuphakelayo alukamboziwe, kepha akukho lutho olubakhohlisayo ukuze lukhule ezindlini zokugcina izithombo - inzuzo yazo izodingeka ngaphansi kwabantu.
Ukuqinisekisa ukuthi uhlelo lusebenza, okokuqala kudingeka lufakwe, ingabe i-caviar izogqokwa esikhaleni. Ukuze wenze lokhu, wasebenzisa amaqanda egqumeni elijwayelekile lesiliva (i-Argyrosomus Regius) neLegrarax ejwayelekile (Dicentrarchus Labrax). Njengoba isintu safunda ukuthutha i-caviar isikhathi eside, kwakudingeka ukuthi sihlole kuphela isici lapho ukwethulwa kwe-rocket kuzokwehluka ngemali engenayo ye-hermetic and ukushisa. Amasampula wamaqanda wezinhlanzi emasondweni akhethekile ahloselwe ukuhlolwa okufanayo nemishini yama-satellite.
Imiphumela eshicilelwe kumagazini obuyekezwe ontanga iyamangaza. Izingxenye ezingaphezu kwezintathu zokudlidliza kwe-caviar yeLavarra (76%) zahlukaniswa yiFry, kanti eqenjini elilawulayo umphumela wawuphakeme kancane - ama-82%. Kepha intamo injengokungathi, kunalokho, yasabela kahle ekudlidlizelweni: Ama-95% amaqanda aba ngama-95% amaqanda, futhi eqenjini elilawulayo kuphela ama-92%. Kuyini ukwazi, kwi-vibratende, okokuqala basebenzise ukwethulwa kwe-soyuz spacecraft, bese kuba khona izilingo banquma ukuqiniseka ukuthi i-caviar imelana nemithwalo ephezulu.
Iphrojekthi yeLunar Hatch ibikhule iminyaka eminingana, i-audiorizer yakhe eyinhloko inguchwepheshe ku-aquacilture Sirill Przyla (Cyrille PrzyLa) kwi-French Research Institute yokuxhashazwa kolwandle). Ngo-2019, ngokusho kwesihloko esise-athikili esemthethweni yale nhlangano, izivivinyo zokuqala zokutshala izinhlanzi esikhaleni zahlelwa ukuchitha cishe ngo-2021. Ukwahlulela ngeqiniso lokuthi azikho izimemezelo ezinkulu okwamanje, noma ucwaningo lwenziwa ngaphandle kwephampu, noma izinsuku zokugcina zayo zihanjiswe ngandlela thile ngenxa yobhubhane.
