Kutalika kwa khansa ya buluu ku Cuba kumafika masentimita 10. Izi zimapangitsa kuti pakhale ma genolphism opanga bwino: Amuna amakhala ndi zibwano zokulirapo, ndipo awiriawiri miyendo yosambira yosinthidwa kukhala gonopodia, genitalia yakunja. Akazi alibe miyendo yoyambira kusambira, kapena ochepa kwambiri kukula kuposa amuna.
Zovala za khansa zimagwira ntchito yowukira ndi kudziteteza. Kusunthaku kumachitika pogwiritsa ntchito awiriawiri a miyendo yakutsogolo. Mimba imapangidwa ndi mbale zisanu, mbali zake zamkati zomwe zimakutidwa ndi zotuluka, mokhazikika akuchita kusuntha kwa pendulum. Maluso a caudal amachoka pagawo lomaliza. Mchirawo umapangidwa ndi zigawo zisanu zokutidwa ndi villi.

Mtundu wa nsomba zazinkhanira zamtambo zimatengera dothi, zakudya, mawonekedwe amadzi. Mtundu ukhoza kusiyanitsidwa ndi mtundu wa bulauni ndi tint yofiyira mpaka mtundu wabuluu.
Cuba wa Blue Crayfish Moyo
Pofufuza chakudya, khansayo imayenda pang'onopang'ono pansi. Nsomba zazinkhanira zimakhala nthawi yambiri pansi pa mizu ya masamba, masamba a algae ndi pansi pa akavalo. Pakupukutira, mawonekedwe a khansa ya buluu amaphulika kumbuyo.
Khansa ikawopa, imayenda modzidzimutsa, ndikuyenda motsimikiza. Mbedza zamtundu wamtambo zimasambira, kukankha mchira wake. Kusuntha kokhala ngati mafunde kumalola khansa kuti ipange liwiro loyenera.
Khansa ya buluu ndi njira yodabwitsa kwambiri.
Mbedza zamtundu wa buluu zimadya chilichonse chomwe chimapezeka pansi: mphukira zamasamba, algae, nsomba zowola zotsalira. Kutalika kwa moyo wa nsomba zazinkhanira za ku Cuba zimafika zaka zitatu.
Kuswana nsomba zazinkhanira
Pakukhwima, yamphongo imatembenuza mkaziyo kumbuyo kwake. Izi zimatha kutenga mphindi zingapo mpaka ola limodzi. Yaikazi imayikira mazira 30-200, imadziphatika kumapazi. Dongosolo la mazira ndi pafupifupi mamilimita awiri.
Wopukusidwa caviar woyamba amakhala wakuda, ndipo patatha milungu iwiri 2 caviar imayamba kudwala. Madontho akuda amawoneka m'mazira - maso a nsomba zazinkhanira. Wamkazi amatha, popanda kukhwima, kuyikira mazira osabereka. Caviar iyi imakhala ndi kuwala kwapinki.
Nthawi ya makulitsidwe ndi masabata a 3-5, kutalika kwa njirayi kumatengera kutentha kwa madzi. Akambukuwa atabwadamuka, amakhala okangamira miyendo ya mayi kwa masiku ena 7-8, pambuyo pake amabalalika. Anthu obadwa kumene omwe sanatalikirane ndi mamilimita atatu. Ana akhanda amasuntha, maonekedwe amakhala ofanana ndi makolo awo. Makansa achichepere amakula msanga m'masabata atatu, afika kale masentimita 1.5. Pa miyezi 1.5, mtundu wawo uli kale pafupi ndi utoto wa akuluakulu.
Kutha msamba mu makanema obiriwira kumachitika m'miyezi 8-10.
Muukapolo, asodzi onama amenewa amangokhala. Kwa nsomba zazikulu zam'madzi za ku Cuba, nsomba zosungidwa ndi malita oposa 100 zimasankhidwa. Samadziyo uyenera kuphimbidwa ndi chivundikiro pamwamba, apo ayi nsomba zamtambo zimathawa. Madzi amathiridwa masentimita 4-5 pansi m'mphepete mwa aquarium.
Monga gawo lamchenga, mchenga, miyala ya miyala ya miyala kapena miyala ya marble imagwiritsidwa ntchito. Mbedza zamtundu wamtambo zimakonda kukangamira pazomera, chifukwa chake malo ojambulidwa amakongoletsedwa ndi fern wa ku Thai kapena cryptocoryne Usteri. Kuphatikiza pa mbewu, payenera kukhala matope obiriwira, machubu achimbudzi ndi miphika mu terarium momwe akhwangwala amatha kubisala.
Kutentha kwamadzi kuyenera kukhala madigiri 20-26, pH 7-8 ndi dH 10-20 ′. Kuchepetsa kwa nthawi zonse ndi kusefera madzi kumafunika. Mbedza zamtundu wamtambo sizingalekerere zabwino za nitrite. Ndikusintha kwamadzi pafupipafupi, nsomba zazinkhanira zimayamba kugunda ndi kuchulukana. Akufuna pazakumwa za oxygen m'madzi ndi kuyera kwake. M'chilimwe, maola masana ayenera kukhala maola 10-12, ndipo nthawi yozizira - 8-10 maola.
Zakudya za nsomba zazinkhanira nthawi zonse zizikhala pansi pa nyanja.
Mbedza zamtchire sizikulimbikitsidwa kuti zizisungidwa limodzi ndi nsomba zam'munsi, chifukwa nsomba zazinayi zimatha kuvulaza. Mwambiri, amakhala mwamtendere, ndipo ngati ali ndi chakudya chokwanira, ndiye kuti samadya nsomba.
Nkhanu zokongoletsera za ku Cuba zimadyetsedwa chakudya chouma cha nsomba, gammarus, daphnia, magazi, mapisa, sipinachi, nyama ndi masamba atsopano.
Kubala Blue Cuban Crayfish
Izi zimatha kuberekanso pachaka chonse. Mbedza zazinkhanira zimasungidwa mu terarium yosunthika yokhala ndi malita osachepera 20 ndi kutentha kwa madigiri 25. Pansi pamayenera kukhala thanthwe la chipolopolo ndi shout zingapo. Nthawi zonse kuchitika kumachitika. Pakadutsa masiku 4 aliwonse, 25% ya madzi abwino amathiridwa.
Yaikazi yomwe imakhala ndi caviar imayilidwira mumadzi ena. Kutentha kwamadigiri 26-27, nthawi yamadzimadzi ndi masabata 3-4. Mu aquarium ndi achinyamata, ndikofunikira kusintha 25-30% yamadzi tsiku lililonse. Sipayenera kukhala ndi chlorine.
Achinyamata amadyetsedwa chakudya chowuma cha mwachangu, ma cyclops, daphnia, artemia, machubu osankhidwa ndi mawombo amwazi, gammarus ndi putas fillet. Achinyamata amabzalidwa mu thanki yosiyana ndi mayi, ndipo malita 60 pa anthu 50 aliyense. Khansa zachinyamata zimamera msanga, kusungunuka kumachitika kamodzi pa sabata, ndipo kamodzi pachaka kumafikiridwa - kamodzi pamwezi.
Matenda okongoletsa nsomba zazinkhanira
Khansa za ku Cuba ndizodziwikiratu kuti zikhale mliri wamtchire, zomwe zimapangitsa mkwiyo wa Aphanomyces astaci. Palibe mankhwala ochiritsira matenda awa. Kuphatikiza apo, nsomba zazinkhanira zamtundu wamtundu zimadwala matenda a porcelain, omwe amakhudza miyendo ndi minofu yam'mimba. Izi zimapha. Matenda amapezeka mukakhudzana ndi nyama yodwala.
Khansa nthawi zambiri imadwala matenda oyaka, pomwe mawanga akuda kapena a bulauni amapangika pa carapace, masamba a thundu ndi alder amayenera kuyikidwa mawaya.
Oimira amtunduwu amadziwika ndi mtundu wolemera wamtambo wabuluu, chifukwa chake amagwiritsidwa ntchito ngati chinyama chokongoletsera cha aquarium.
Zikhansa zimatha kukhudzidwa ndi majeremusi, nthambi za Branchiobdella sp., Zomwe zimangokhala pamavuto awo, koma zimangoyang'ana kwambiri ma gill. Pofuna kuthana ndi nsomba zazinkhanira za parasites, zimakonza malo osambira mchere.
Ndikofunikira kulingalira kuti nkhanu za buluu zokongoletsa zimafa ndi mawonekedwe ambiri a nitrate m'madzi.
