Iinkqubo eziqhelekileyo zokucocwa kwamanzi amdaka ezindlini zihlala zifuna umhlaba omninzi kunye nophuhliso lweziseko ezingundoqo oluntsonkothileyo, olunokuba lukhetho olubiza imali eninzi nolungazinzanga kwimimandla yasezidolophini. Nangona kunjalo, izikhongozeli zokucoca amanzi amdaka asekhaya adityanisiweyo anciphisa kakhulu indawo efunekayo kunye neendleko zokwakha ngokudibanisa zonke iiyunithi zokucoca ngaphakathi kwesikhongozeli esinye. Ngoyilo lwaso oludibeneyo kunye nemodyuli, isixhobo sinokulungiswa ngokuguquguqukayo kunye nokunyuka njengoko kufuneka, ngoko ke, iindawo zokucocwa kwamanzi amdaka zisetyenziswa ngokubanzi kwiindawo ezininzi ezinje ngeendawo zokuhlala ezincinci, iindawo zeminyhadala yethutyana, umtsalane wabakhenkethi, iipaki zoshishino, iindawo ezikude. kunye nempendulo kaxakeka.
Ngokubanzi, izikhongozeli zokucocwa kwamanzi amdaka zisebenzisa uluhlu lweenkqubo zonyango, ezinje ngonyango lomzimba, unyango lwebhayoloji kunye nonyango lwekhemikhali, ukususa izinto eziqinileyo ezimisiweyo, izinto eziphilayo, initrogen, iphosphorus kunye nezinye izinto ezingcolisa amanzi amdaka. Ukusebenza kunye nokusebenza kakuhle konyango kwezi nkqubo kuxhomekeke kuyilo kunye nokucwangciswa kwezixhobo, kunye nomgangatho wokusebenza kunye nokugcinwa.
Ukuqinisekisa isiphumo esilungileyo sonyango lwezixhobo zokucoca amanzi amdaka, ezi zinto zilandelayo zibalulekile:
Okokuqala, uyilo olufanelekileyo kunye nokukhethwa: ngokweempawu zamanzi amdaka kunye neemfuno zonyango, khetha inkqubo efanelekileyo yokonyango kunye neenkcukacha zezixhobo.
Okwesibini, ukufakwa kobuchwephesha kunye nokugunyaziswa: ukufakwa okuchanekileyo kunye nokugunyaziswa kwezixhobo kuyisitshixo sokuqinisekisa ukusebenza kwayo okuqhelekileyo kunye nokufezekisa umphumo wonyango olindelekileyo.
Okwesithathu, ukugcinwa rhoqo kunye nokubeka iliso: ukugcinwa rhoqo kunye nokuhlolwa kwezixhobo zokuqinisekisa ukusebenza okuqhelekileyo kwezixhobo, kunye nokubeka iliso kunye novavanyo lwesiphumo sonyango.
Okwesine, uqeqesho lwabaqhubi: Abaqhubi kufuneka baqhelane neenkqubo zokusebenza kunye nokugcinwa kwezixhobo zokuqinisekisa ukusetyenziswa kwazo ngokufanelekileyo.
Ukongeza, imimandla eyahlukeneyo inokuba nemigangatho ehambelanayo yokusingqongileyo kunye neemfuno, kwaye umphumo wonyango wesixhobo kufuneka uhlangabezane nale migangatho. Ukuba uyathandabuza malunga nefuthe lonyango lwesixhobo esithile, kungcono ukubhekisela kulwazi lobugcisa olunikezwa ngumenzi wezixhobo, iingxelo zovavanyo olufanelekileyo, okanye udibane nenjineli yobungcali yokusingqongileyo ukuze uhlolwe.
Ukhuseleko lokusingqongileyo izixhobo ezidityanisiweyo zokucocwa kwamanzi amdaka zinokuphatha amakhaya ukuya kuthi ga kwi-10,000 yeetoni zamanzi amdaka, kukho abarhabha, i-sturgeon emhlophe, i-blue whale ezintathu eziphambili zokucocwa kogutyulo lwelindle ukuze ukhethe kuzo, ukukhuselwa kokusingqongileyo kuzibophelele ekuncedeni ulwakhiwo olutsha. emaphandleni ngocwangco ukuze kuncedwe amanzi aluhlaza neentaba eziluhlaza zichume.
