I-crayfish emifushane yaseMexico (Cambarellus mantezumae), ebizwa nangokuthi iMrayzuma dwarf crayfish, ingeyesigaba se-crustacean.
Ukusabalala komdlavuza omncane waseMexico
Kusatshalaliswe emzimbeni wamanzi waseMelika Ephakathi, otholakala eMexico, eGuatemala, eNicaragua. Lolu hlobo lutholakala kulo lonke elaseMexico, luhlala eLake Chapala esifundazweni saseJalisco, empumalanga echibini le-crater iPueblo, emiseleni yaseXochimilco, ngaseMexico City.
Izimpawu zangaphandle zomdlavuza omncane waseMexico
I-crayfish encane yehlukile kubantu bezinye izinhlobo ze-crustacean ngosayizi wayo omncane. Ubude bomzimba wayo bungu-4-5 cm. Umbala wekhava le-chitinous uyahluka futhi unombala ompunga, onsundu nonsundu ngokubomvu.
Indawo yokuhlala
I-Pygmy crayfish itholakala emifuleni, emachibini, emadamini nasemigodini. Uncamela ukucasha phakathi kwezimpande zohlaza olusogwini ngamamitha ayi-0.5. Kutholakala ngobuningi kwezinye izingxenye zebanga, yize ukutshalwa kwe-carp emapulazini ezinhlanzi kuthinta ukwehla kwenani lala ma-crustaceans, kepha akulona usongo olukhulu.
Ukudla okunomsoco womdlavuza waseMexico
I-crayfish encane yaseMexico izondla ngezitshalo zasemanzini, imfucumfucu ephilayo kanye nezidumbu zama-vertebrate.
Ukukhiqizwa kabusha kwe-crayfish yaseMexico
Izinhlobo zemifantu ezalwa ngo-Okthoba kuya kuMashi. Owesifazane ngamunye ubeka amaqanda ayi-12 kuya kwayi-120. Ukushisa kwamanzi, i-pH kanye ne-oxygen okuhlushwa akunamphumela omkhulu ekuthuthukisweni. Izimo zokuphila ezilungile: ukugxila komoya-mpilo kusuka ku-5 kuye ku-7.5 mg L-1, i-asidi ku-pH uhla luka-7.6-9 kanye nokushisa okungu-10-25 ° C, kuyaqabukela kudlule u-20 ° C.
Umdlavuza omncane waseMexico uchazwe njengezinhlobo ezibekezelela umzimba. Ama-crustaceans amancane anombala onsundu ngokukhanyayo, bese e-molt futhi athole umbala wabantu abadala.
Izizathu zokwehla
Ama-crayfish amancanyana aseMexico avunwa njalo, kepha abukho ubufakazi bokuthi ukubamba kunomthelela omubi kakhulu enanini nasezimeni zala ma-crustaceans.
Ukwehla kwesibalo sabantu kuyabonakala emizimbeni yamanzi engajulile, lapho i-turbidity yamanzi iyakhula futhi ngaleyo ndlela inani lokukhanya elidingekayo ekukhiqizeni ama-macrophytes liyancipha. Ukulima iCarp nakho kungadala ukwehla okwenziwe endaweni ezindaweni eziningana. Le nqubo ihamba kancane futhi ayisongeli ubukhona bazo zonke izinhlobo zezinto eziphilayo, ngakho-ke izinyathelo ezikhethekile zokuvikela azisebenzi kwi-crayfish yaseMexico.
Ukugcina ama-crayfish amancane ku-aquarium
I-Pygmy crayfish ingeyezinhlobo ze-thermophilic crustacean. Abantu balezi zinhlobo baphila emanzini asezindaweni ezishisayo kanye nezinhlanzi ezingaphandle ezihlala ezimeni ezifanayo. Ababelethi baye bafuya ama-morphs akhethekile ama-crayfish amancane. Banombala osawolintshi noma obomvu wethoni elinganayo; kukhona nabantu abanemivimbo ebiziwe. Umbala wekhava le-chitinous uncike ekwakhiweni kwamakhemikhali kwamanzi nokudla.
Ukugcina i-crayfish encane ekuthunjweni, udinga i-aquarium enomthamo wamalitha angama-60 noma ngaphezulu ngenhlabathi, izitshalo, lapho kuhlungwa khona amanzi kanye ne-aeration esebenzayo. Inhlabathi ithelwa okungenani ama-6 cm ukuphakama, imvamisa amatshe amancane (0.3 - 1.5 cm), amatshe omfula nolwandle, izingcezu zezitini ezibomvu, ubumba olunwetshiwe, inhlabathi yokufakelwa yama-aquariums ifanelekile.
Ngokwemvelo, ama-crayfish amancanyana athola indawo yokuhlala, ngakho-ke e-aquarium bacasha emigodini embiwe noma emihumeni yokufakelwa.
Izitshalo ezinezimpande ezithuthukisiwe zifakwa esitsheni: i-Echinodorus, i-Cryptocorynes, i-Aponogetones, izimpande zezitshalo zasemanzini ziqinisa inhlabathi futhi zivimbele imigoqo ekuweni. Izindawo zokufakelwa ezingekho emthethweni zifakiwe: amapayipi, izinkuni ezikhukhulwayo, ukusika isaha, amagobolondo kakhukhunathi.
Umsebenzi we-aeration nobuningi bokuhlungwa kwamanzi kuncike kubukhulu be-aquarium nenani lama-crustaceans. Amanzi akwi-aquarium aguqulwa kanye ngenyanga, futhi kungezwa ingxenye yesine noma yesihlanu kuphela yoketshezi. Ukunikezwa kwamanzi ahlanzekile kuthinta ukukhiqizwa kabusha kwazo zonke izinto eziphila emanzini ezihlala e-aquarium. Lokhu kunciphisa inani lezinto eziyingozi futhi kwandisa okuqukethwe komoya-mpilo okudingekayo empilweni yabakhileyo be-aquarium. Lapho kulungiswa i-crayfish yaseMexico, ukwakheka kwamanzi okuphefumula kuyagcinwa, futhi nemibandela yokuboshwa, ebekiwe ezincomweni, iyagcwaliseka.
I-crayfish yemifino ayifuni kakhulu ekwakhiweni kwamaminerali kwamanzi. Izinhlobo eziningi ze-crayfish zihlala emanzini ezinokushisa okungama-20 ° -26 ° C, pH 6.5-7.8. Amanzi anokuqukethwe okuphansi kasawoti wamaminerali awafanele ukuhlala, njengoba inqubo yemvelo yokuncibilika nokuguqulwa kwekhava le-chitinous iphazamisekile.
Ama-crayfish amancane agwema ukukhanya kwelanga okukhulu; emizimbeni yamanzi yemvelo asebenza kakhulu kusihlwa. I-aquarium equkethe i-crayfish imbozwe isembozo noma isiliphu sekhava. Izilwane zasemanzini kwesinye isikhathi ziyashiya i-aquarium zife ngaphandle kwamanzi. Ama-crayfish amancane adla ukudla okuhlukahlukene, ondliwa ngokudla kwezinhlanzi.
Bacosha izingcezu zenyama, badle inyama egayiwe egayiwe, ama-cereal flakes, i-cottage shizi enamafutha aphansi, i-caviar, ama-granules anomsoco, banganikezwa izingcezu zezinhlanzi ezintsha, ama-bloodworms, ukudla okulungiselelwe okwenzelwe izinhlanzi zasemanzini. Ama-crustaceans amancane aqoqa izinsalela eziphilayo ezansi, adle amaqanda nenhlanzi ethosiwe, izibungu. Ngale njongo, ama-gastropods ahlaliswa e-aquarium: amakhoyili kanye ne-nat, inhlanzi: ama-mollies, i-pelicia. Ama-crayfish amancane aseMexico anomkhawulo wokudla kwansuku zonke. Izingcezu ezisele ze-crayfish zifihlwe ezindaweni zokukhosela, zibola ngemuva kwesikhashana. Amanzi aba namafu, amagciwane ayanda kuwo, bese kuvela iphunga elibi. Amanzi kufanele ashintshwe ngokuphelele, ngaphandle kwalokho izimo ezinjalo zivusa ukugqashuka kwezifo ezithathelwanayo bese kufa umdlavuza.
