I-Aquaculture: Ikusasa Lezokudoba Okusimeme

I-aquaculture, ukutshalwa kwezinhlanzi nezinye izinto eziphilayo zasemanzini, ithole ukuduma njengenye indlela esimeme kunezindlela zendabuko zokudoba.Imboni yezolimo yasemanzini yomhlaba wonke ibikhula ngokushesha eminyakeni yamuva futhi kulindeleke ukuthi iqhubeke nokukhula emashumini eminyaka ezayo.Esinye sezici zokufuywa kwezilwane zasemanzini esithola ukunakwa okukhulayo ukusetshenziswa kwezinhlelo ze-aquaculture recirculating (RAS).

I-Recirculating Aquaculture Systems

Izindlela zokuphinda zijikeleze izinhlanzi zasemanzini ziwuhlobo lokufuywa kwezinhlanzi okubandakanya ukutshalwa kwezinhlanzi ngokuvalekile endaweni equkethwe.Lezi zinhlelo zivumela ukusetshenziswa kahle kwemithombo yamanzi namandla, kanye nokulawulwa kokulahlwa kwemfucuza kanye nokuqubuka kwezifo.Izinhlelo ze-RAS zisiza ekunciphiseni umthelela wezindawo zokudoba zendabuko futhi zinikeze izinhlanzi unyaka wonke, okuzenza zibe inketho ekhangayo kubo bobabili abadobi bezohwebo nabezokungcebeleka.

Izinsiza ze-Aquaculture

Impumelelo yokuzungeza kabusha izinhlelo zokufuywa kwezilwane zasemanzini incike ezinhlobonhlobo zemishini ekhethekile, okuhlanganisa kodwa kungagcini nje:

Izigubhu ze-Aquaculture: Lezi zihlungi zisetshenziselwa ukususa udoti oqinile kanye nemfucumfucu emanzini.Izihlungi zezigubhu zizungeza kancane, zivale imfucuza enetheni kuyilapho zivumela amanzi ahlanzekile ukuba adlule.

Ama-Protein Skimmers: Lawa madivaysi asetshenziselwa ukususa izinto eziphilayo ezincibilikisiwe emanzini, njengokudla ngokweqile kanye nemfucuza yezinhlanzi.Ama-protein skimmers asebenza ngokuheha nokukhipha lezi zinto ngenqubo ebizwa ngokuthi i-foam fractionation.
Imishini ye-aquaculture iye yahamba ibanga elide eminyakeni yamuva, okwenza kube lula futhi ngokuphumelelayo ukutshala izinhlanzi nezinye izinto eziphilayo zasemanzini.Ukuthuthukiswa kwezinhlelo ze-RAS kanye nezinsiza ezihambisana nazo kuye kwavula amathuba amasha okudoba okusimeme emhlabeni wonke.Njengoba imboni iqhubeka nokukhula, kungenzeka ukuthi sizobona intuthuko eyengeziwe ezinsizakalweni zezilwane zasemanzini ezizosiza ukwenza ukufuywa kwezinhlanzi kusebenze kahle kakhulu futhi kungayingeni imvelo.
