Ukukhulelwa nokukhula kwama-crayfish ekhaya akuvamile futhi sekusetshenziselwe isikhathi eside. Umehluko ulinganiselwe kuphela: obani leli bhizinisi, futhi ubani owenza lokho ngenjabulo yabo.
Indawo yokuzalanisa izinhlanzi
Ukuze ukhiqize umdlavuza ungasebenzisa kokubili ama-aquariums namachibi wonke. Abanye bahlela amachibi aphelele. Ukuze ufake ama-aquariums uzodinga igumbi elinokushisa okuhle. Futhi ngaphakathi kwamanzi, uhlele amatshe angenalutho nezitshalo zamanzi. Izinhlelo zokuhlunga okuphoqelekile kanye ne-air compressors .
Idamu lihlelwe emgodini olungiselelwe ngokukhethekile lapho isitsha se-polypropylene sifakwe khona. I-compressor ye-pneumatic ikhiqiza i-aeration. Emanzini okubhukuda avame ukukhula kusuka emaqanda ase-sagolets.
Kuyiqiniso ukuthi ukukhiqiza okufakelwayo kwenani elikhulu lamagciwane kuyodinga idivaysi yasemanzini, okuyinto elula uma unendawo enkulu enkulu. Uma ukujula kwesitsha kungavamile ukudlula amasentimitha angama-70, ichibi kufanele libe namamitha amabili. Futhi le ndawo ayisekho amamitha angu-2 noma ayi-6, kodwa ayi-0.3 hektare. Ukuthi amanzi awashiyi echibini, phansi kwawo kufanele kuhlanganiswe nefilimu engenawo amanzi. Kodwa ngesikhathi esifanayo kubalulekile ukuqhuba amapayipi amabili - amanzi kanye nokunikezwa kwamanzi ahlanzekile. Esigodini udinga ukubeka izitshalo zasemanzini, futhi ucebise ulwandle ngezihlahla kanye nezihlahla.
Ukuze uqale ukuzala i-crayfish, kubalulekile ukukhetha abantu abavuthiwe ngokobulili, abaneminyaka engu-4-5 ubudala. Kuyaziwa ukuthi uma ama-crayfish athola ukunakekelwa okufanele, angaphila iminyaka engama-25, kanti owesifazane oyedwa angakunika i-crayfish engama-30 kungakapheli unyaka owodwa.
Izinhlobo ze-khansa nezindlela zokuzalanisa
Ukuhlunga nokugcinwa kwe-crayfish kufanele kwenzeke emanzini amasha. Bambisana ikakhulukazi ekwindla. Futhi entwasahlobo ungabona ukuthi ama-crustaceans amancane avela kanjani kumaqanda.
Nakuba ekhaya, uma uzalisa i-aquarium crayfish, inqubo yokuthuthukisa amaqanda ingaba ngesivinini futhi ifinyelelwe isikhathi esingangezinyanga ezintathu. Ukushisa kwamanzi emfuyo yezilwane akufanele kudlule ama-degree angu-24. Umsebenzi wezilwane ubonakala ebusuku, ngesikhathi sosuku balala kakhulu eminyangweni yabo.
Ukondla ama-crayfish afanayo kudingeka izitshalo ezintsha zasemanzini, ama-shellfish, ama-bloodworms, izinambuzane, izidumbu zezinhlanzi, izibungu zomhlaba, kanye namaxoxo. Abantu abadala bakudla ikakhulukazi ngenkathi efudumele, futhi ebusika baqala ukulala, belele ubuthongo, futhi ngokufanele, badla kancane.
Uma ukuzalanisa i-crayfish ku-aquariums noma amachibi okufakelwa, lapho izinga lokushisa kwamanzi lingekho ngaphansi kwama-degree angu-15, udinga ukondla ama-crayfish unyaka wonke. Amazinyo anamaqanda atshalwe echibini kuphela lapho amanzi egoqa kuze kufike kuma-degree angu-20. Kubalulekile ukubuka ukubonakala komama ozayo - uma beba ne-foam emlonyeni kanye nezigqoko ziyancipha, zitshalwe echibini elihlukile, lapho ukushintshaniswa kwamanzi kwenzeke ngesilinganiso esingu-0.6 - 0.7 l / min.
Lapho izimpungushe zikhishwa emaqanda zizimele, abesifazane bayatshala echibini lapho bengakwazi khona ukukhipha futhi, mhlawumbe, beshade nabesilisa ukuze baqhubeke nezingane. Ukuzimela kwezimpungushe kungathathwa ngokuthi bayeka ukubuthana inqwaba, bangafihleki esikhathini esiyingozi ngaphansi komsila womama, futhi bahambe ngokushesha ekufuneni ukudla phansi kwekhaya labo.
Ngemuva kokufinyelela eminyakeni yobudala - izinsuku ezingu-90, zingatshalwa endaweni echibini ukuze ziqhubeke nokukhula nokuthuthukiswa kwazo ezimweni zemvelo.
Ukuzaliswa komdlavuza we-Cuban ohlaza okwesibhakabhaka, othanda ukukhanya okungenani amahora angu-10, futhi futhi ukugxila ezitshalweni zamanzi, kulula kakhulu. Zondla ngendlela efanayo nezinye izinhlanzi, kuphela ukudla okumele ku-aquarium amahora angu-24 ngosuku. Ihluma unyaka wonke. Futhi isikhathi sokuvuthwa kwamaqanda ekushiseni kwamanzi ama-26-27 degrees kwenzeka emavikini amathathu.
