Ukuzalanisa i-crayfish ekhaya sekuyisikhathi eside sekuyisikhathi sokuzilibazisa nje: namuhla ibhizinisi elizuzayo elingadingi izimali ezinkulu futhi kufanelekile ukuqaliswa, kokubili ngokulingana okukhulu nokuthobekile. Lesi silwane asidingi ukondla okubizayo futhi sithenga izesekeli eziningi zokugcina.
Indlela yokuqukatha umdlavuza ekhaya?
Isici esiyinhloko, okuzodingeka sinqunywe kusengaphambili - yisilinganiso sokukhiqizwa kokudla okuthandwayo. Njengoba kungenzeka ukuzala amakhemikhali ekhaya ezinqolobaneni zokufakelwa futhi ezigelezayo, konke kuxhomeke ngokuphelele ekufisweni nesifiso sezimali:
- Uma umndeni uhlela ukuhlinzeka inyama kuphela ngezidingo zabo, khona-ke kuzoba khona amanzi anele futhi amaningana - angafakwa endaweni yangasese noma egumbini lomsebenzi.
- Emabhizinisini amancane, ukuzalanisa i-crayfish ekhaya kungenziwa echibini elihlomele endaweni yangasese noma endaweni yasemadolobheni.
- Inzuzo emangalisayo iyohlinzekwa yichibi lokufakelwa, futhi uma kukhona amabili, khona-ke umdlavuza ungakhula ukuthengiswa unyaka wonke.
I-crayfish ekhaya emanzini
Akunqatshelwe ngisho nokuzama ukuzalela lezi zilwane emathonjeni afanayo kanye nenhlanzi noma i-squid. Amanqamu angakwazi ukuziphatha njengama-cannibals, abhubhise omakhelwane ku-aquarium. Umthetho oyinhloko ukugcina amanzi ahlanzekile, ngoba abasha bafa ngokushesha nje lapho kuphenduka ama-green and microorganism ezilimazayo. Phakathi kwezincomo eziyinhloko ezenza kube lula ukukhiqiza ama-crayfish ekhaya labaqalayo, kufaka phakathi:
- Ubukhulu obuncane be-aquarium ezifanele ngamalitha angu-250: izilwane ezinkulu ezingu-7-8 kuphela ezingahlala ngevolumu encane ngesikhathi esisodwa.
- Ngezansi kufanele kubekwe inhlabathi enkulu namatshe amatshe, izinkuni zokuhlobisa kanye namapayipi e-ceramic - i-crayfish ekhululekile kakhulu ukuze iphile uma kunezindlu zokuhlala ezikude.
- Ngenkathi ebandayo, izilwane ezifuywayo zidinga ukushisa - okukhethwa kukho okukhethekile kunikezwa kuzihlungi nge-matshonti e-thermostat eyakhelwe ngaphakathi.
Ukukhiqiza i-crayfish echibini ekhaya
Umthamo wokuzalanisa ungazicubungula wena futhi udwebe phansi nge-rubble enkulu ehlanganiswe nobumba. Ukukhula kwama-crayfish ekhaya echibini kunesibalo esisodwa esibaluleke kakhulu - singasetshenziswa ebusika, okuzokwenza ukwandisa umkhiqizo okungenani kabili, njengoba ama-crayfish angeke aqede ngesikhathi sokubanda. Izilwane zidla njalo zikhule, okuzokwenza ukwanda okubonakalayo kwesisindo nobukhulu bomuntu ngamunye. Ngesikhathi esifanayo nabo kungenzeka ukuba bakhule ezinye izinhlobo ze-benthic mollusks - i-perlite noma i-scallop.
Ukwelashwa komdlavuza
Ukuze kuzalwe, kunconywa ukuthi izinhlobo zezilwane zaseMpumalanga Ekude naseYurophu, ngoba zihlukumezeka ezimweni zokuboshwa futhi ezingabizi. Zihlukaniswe zibe yi-lake and river crayfish, kodwa okwesibini angeke itshalwe ngamathangi ngamanzi amile - afaneleke kuphela amachibi okufakelwa. Kule ndawo yonke, ukunakekelwa kuhlanganisa ukugcina imithetho elandelayo:
- Ukuhlanzwa kwegumbi hhayi nje kuphela ngaphambi kokuqaliswa, kodwa futhi nokuqhutshwa komjikelezo wokuphila wezimvukuzane. Imishini eyisihluthulelo yokuzalanisa i-crayfish ekhaya ihlanzekile ochwepheshe ehlonyelwe uhlelo lokuzala kanye nesondlo.
- Ukuhambisana nokulinganisela kwe-oxygen.
- Ukukhethwa kokudla kwekhwalithi yamagciwane.
- Ukudala izimo zokukhiqizwa kwamadoda nabesifazane.
Ungondla kanjani umdlavuza wamanzi ekhaya?
Ukondla abasha imikhiqizo efanayo basetshenziswa njengabantu abadala. Ungakwazi ukuzidla ngokufunda ukuthi badla ama-crayfish ekhaya, noma uthenge ukudla okulungile. Ekudleni okunempilo, okuyinto lezi zilwane ezidinga, kumele zibandakanye amafutha, imifino enezinga eliphakeme le-fibre, amaprotheni kanye ne-mineral supplements ne-calcium. Umkhuba wansuku zonke wokudla ngomdlavuza kufanele ube ngu-4-5% wesisindo sawo. Kungabandakanya:
- izaqathe ezisikiwe;
- izinkukhu;
- izinhlanzi ezifile;
- izibungu zomhlaba;
- izitshalo zokudla okusanhlamvu;
- amazambane abilisiwe.
Ukukhiqizwa kwekhrayfish ekhaya
Ukuzala kwakuyinzuzo, kubalulekile ukucabangela ilitha langempela ukuthi i-shellfish inganikeza. Amantombazane ajwayelekile enza ama-crustaceans angaba ngu-200 ngonyaka, kodwa ahlala ephilayo futhi akhule ibe ngosayizi ofanele kuphela 20%. Ukwandisa ngokuphawulekayo lesi sibalo kungaba, ukugcina umkhuba wokudla - izihlobo ezindala ngeke zidle intsha. Kuneminye imithetho ekhuthaza ukukhiqiza ngesikhathi sokutshala ama-crayfish ekhaya:
- Ukuxubana nabantu abadala kwenzeka ekwindla. Inombolo ibalulekile ukuzama ukulawula ngendlela yokuthi owesilisa omdala abe nabesifazane ababili - ngeke akwazi ukutshala ngaphezulu. Ochwepheshe abanolwazi olubanzi lokuthi bazalise kahle kanjani i-crayfish ekhaya baqinisekiswa ukuthi uma owesilisa ebona owesifazane wesithathu, uyodla.
- Ngemuva kokuqeda, zonke izinsikazi zifakwa emathangi ahlukene: ekupheleni kwentwasahlobo, amaqanda azohamba ngaphansi komsila futhi angabonwa ngeso lengqondo.
- Ngemuva kokuqothula ama-crayfish, owesifazane uyasuswa - lokhu kuzokwenza ingane ikhule.
