Abanye abantu bazalela i-crayfish emakhaya nge-aesthetics, kanti abanye bakwenza njengebhizinisi, ngoba umsebenzi onjalo ungaletha inzuzo enkulu. Kodwa-ke, kuzimo zombili, ungakhohlwa ngokubapha ukudla ekhaya. Umdlavuza yizilwane ezi-omnivorous futhi awuthandi ngokukhethekile ngokudla, ngakho-ke angadla kokubili ukudla kwezitshalo nezilwane. Ngokuvamile, i-crayfish idla lokho ezikuthola kaningi, ngakho ukuzigcina akunzima.
Lapho udla ekhaya, kungakuhle ukuthi unikeze i-crayfish indawo eseduze ngangokunokwenzeka nendawo yabo yemvelo, ngoba bayondla futhi bafune ukudla, bathembele ezinzwa zabo. Kunconywa ukuthi uthele isihlabathi somfula esihlanzekile ethangini bese uphonsa amatshe ambalwa lapho.
Inketho ekahle yokwenza ngcono ukuhlinzekwa kokudla ekhaya kungaba ukubekwa komanyolo wezinto eziphilayo namaminerali, imvamisa lokhu kwenziwa ngisho nangaphambi kokuba ithangi ligcwale amanzi. Ubungako ngehektha elilodwa lomhlaba cishe bumi ngokulandelayo:
- I-Superphosphate - 1kg;
- I-ammonium nitrate - 50 kg.
Uma ungenayo imali kamanyolo obizayo, ungasebenzisa noma yiluphi uhlobo lwemidumba. Lolu hlobo lomanyolo luzothuthukisa amanzi nenhlabathi nge-nitrogen. Le ndlela ayishibhile nje kuphela, kodwa izokuvumela futhi ukuthi unwebise ukusetshenziswa kwedamu, ngoba iyindawo elunge kakhulu emvelweni.
Ngaphezu kwalokho, ngesifiso esihle sezilwane ezifuywayo ekhaya lakho, kufanelekile ukucubungula imingcele efana nokushisa nobumuncu bamanzi. Ngakho-ke, uphawu lwe-pH kufanele luvele kusuka ku-7 kuye ku-8.5. Kepha ngokushisa kulula kancane. Isici esiyinhloko ukuthi izinga lokushisa kwamanzi alikho ngaphansi kwezinga eli-1, futhi uma lisondele ku-15, i-crayfish izozizwa ikhulu kuwo.
Ukondla okuseduze nemvelo
I-Crayfish inomqondo othuthukile wokunuka. Ngaphansi kwezimo zemvelo, bathola inhlanzi ebolile ngokushesha kunokusha, ngoba iphunga layo liya ligqama kakhulu njengoba libola. Emifuleni, uvame ukubabona belwa esidunjini esidala senhlanzi.
Amehlo abo nawo athuthukile kahle. Ngakho-ke, ukubona okuthile okubomvu, i-crayfish izokuzama nakanjani, iphambanise into yangaphandle ngengcezu yenyama.
Ngaphandle kokuziphatha kwabo kabi nangokulangazelela ukudla yonke into enephunga futhi ebomvu, kusesele nesici esisodwa esidingekayo lapho ubondla. Lezi zilwane zivame ukudla ulwelwe olunothile lwe-lime. Bayayidinga ekukhuleni okunempilo kwegobolondo, ikakhulukazi le "nto yokwakha" abayidingayo ngesikhathi se-molt, lapho bechitha "izikhali" zabo ezindala futhi bekhulisa entsha. Lezi zitshalo zifaka:
- Izinhlobo zezitshalo zeChara;
- Hornwort;
- Elodea.
Ngaphandle kwe-crayfish, cishe akekho umuntu ozondla ngalezi zitshalo, ngoba okuqukethwe okuphezulu kukalamula kuzinikeza ubunzima, okuyinto lezi crustaceans ezingazideleli. Lokhu kufanele kubhekwe lapho kubondliwa ekhaya. Zama ukwandisa inani le-lime ekudleni kwakho kwe-crayfish.
Ngaphezu kwezitshalo, ama-crayfish adla izilwane ezahlukahlukene zasemanzini, ikakhulukazi izilwane ezisencane. Izinhlobo ezahlukahlukene zama-invertebrate afana ne-daphnia kanye ne-cyclops zilungele zona njengokudla. Futhi, iminenke, izibungu, izibungu ezahlukahlukene, futhi, uma ngenhlanhla, onoshobishobi bezinhlanzi ezincane bangaba ukudla.
Kuyinto efiselekayo futhi ukuzalela i-phyto- ne-zooplankton echibini. I-Crayfish inethemba elihle kakhulu ngale ndawo. Lezi zinhlobo zisebenza njengokudla, kokubili i-crayfish uqobo kanye nokudla kwazo.
Akusizi ngalutho ukuthi izilwane ezisencane okukhulunywe ngazo ngenhla, ngoba ngobudala, okuncamelayo kokudla kuma-crayfish kushintsha kakhulu, ngakho-ke, eminyakeni ngayinye badinga ukudla okuthile:
- Ngaphansi kweminyaka. Kule minyaka, ama-59% ezondla ze-crayfish yi-daphnia, kanti ama-25% angama-chironomids.
- Lapho sifinyelela kubude obungamasentimitha ama-2, izibungu ezinambuzane ezahlukahlukene zifakiwe ekudleni, okungakha ama-45% wokudla okuphelele.
- Insimu engamasentimitha amathathu ubude, abancane bonyaka baqala ukudla imollusk.
- Lapho sebefinyelele ku-4 cm, baqala ukudla izinhlanzi.
- Lapho i-crayfish iba yintsha (8-10 cm ubude), ama-amphipods ahamba phambili ekudleni kwawo, amaphesenti awo angafika kuma-63 enani eliphelele lokudla.
Uma wenza izimo ze-crayfish ekhaya kusengaphambili, eduze kwemvelo, khona-ke ukudla kwabo kuzobuyiselwa ngo-90%, okuzoqinisekisa ukukhula kwabo okuzinzile nokunempilo, futhi uzokonga imali eningi.
Ukondla nokufakelwa kokuzenzela
Uma ungenalo ithuba lokudala izimo ezikahle ze-crayfish ekhaya, kufanelekile ukunaka ukudla okwenziwe yizilwane ezifuywayo.
Okokuqala, qiniseka ukuthi yiziphi izindawo abahlangana kuzo kaningi, bese uzama ukuphonsa ukudla kule ndawo. Kuyafaneleka futhi ukukhumbula ukuthi i-crayfish yizilwane ezihamba ebusuku, ngakho-ke kungcono ukuzondla kusihlwa.
Kungcono ukondla izingane ezingaphansi kweminyaka:
- Inyama egayiwe (inhlanzi, inyama);
- Imifino ebilisiwe;
- Ukudla okuyinhlanganisela kwezinhlanzi ezidla imifino.
Kubalulekile ukukhipha ngaphandle ukudla okunamafutha okuhlukahlukene okungonakalisa amanzi, okuholele ebhadaneni. Ngokwesilinganiso sokukhula esisheshayo kwezimvu zangaphansi ekhaya, ukuphakelwa okuhlukahlukene kungangezwa ekudleni.
Njengokudla kokufakelwa kwe-crayfish yabantu abadala, okulandelayo kufaneleke kakhulu:
- Inyama eyonakele;
- Izinhlanzi ezibolile;
- Ukuthena imifino;
- Okusanhlamvu okumanzi;
- Izingcezu zesinkwa.
Ngaphezu kwalokho, zingadliwa yi:
- Izikelemu;
- Amaxoxo amancane;
- Isibungu segazi.
Kusukela ekudleni, ungaqonda ukuthi i-crayfish iyesabeka njenge-carrion ehlukile, kepha-ke, kuhle ukukhumbula ukuthi lolu hlobo lokudla lungcolisa i-aquarium. Ukuze ugweme ukuwohloka okusheshayo kwamanzi, ekhaya, kungakuhle ukuthi uphendukele enyameni eyomisiwe kancane ngangokunokwenzeka njengokudla ekhaya. Futhi lesi sidlo kufanele sinikezwe ku-feeder ekhethekile, ongazenzela yona ekhaya.
Thatha ibhodi elidala, okungcono u-10-15 cm ububanzi, ubone isiqeshana esingama-20 cm bese ubethela emaphethelweni amabhodi, angabi ngaphezu kwamasentimitha ama-2. I-feeder isilungile, akukho okuxakile.
Kunzima ukusho ngenani lokudla okudingekayo kumuntu oyedwa womdlavuza, kodwa-ke, kufanelekile ukucabanga ukuthi awukwazi ukondla lezi zilwane uma kukhona ukudla ku-feeder. Ukubonakala kwamanzi kungasiza ekunqumeni lokhu:
- Uma ubona i-feeder futhi ingenalutho, zizwe ukhululekile ukunikeza i-crayfish isabelo esisha sokudla.
- Uma amanzi enamafu, kufanelekile ukukhipha okuphakelayo bese ubheka ukuthi ngabe ukondla okwengeziwe kuyadingeka yini.
Kuzona zozimbili lezi zimo, kunomthetho olula okufanele uwukhumbule - kungcono ukwehliselwa ngaphansi kunokushiya ukudla okwengeziwe e-aquarium. Ukudla okudala, njengoba kubola, kuzovala amanzi, ngemuva kwalokho amabhaktheriya abangela izifo angakhula kuwo, okuholele ekuhlaselweni yi-crayfish.
Olunye ulwazi oluwusizo
Kuyafaneleka futhi ukukhumbula ukuthi ehlobo udinga ukudla okwengeziwe, ngoba ebusika ama-crayfish awakhuli noma achithe, okusho ukuthi anesidingo esiphansi kakhulu sokudla. Futhi uma uzalela i-crayfish ekhaya endaweni esondelene nemvelo, khona-ke ngesikhathi sasebusika isicupho kufanele simiswe ngokuphelele, kepha kungcono ukukuqala ngoMashi noma ngo-Ephreli.
Ukondla i-crayfish ngokulungiselela kahle akunzima nje kuphela, kepha futhi kukonga impela. Ukudla kwabo kushaya isikhwama esincane kakhulu kunokudla kwezinhlobo eziningi zezinhlanzi zasemanzini.
