Mbalame yotchedwa crayfish ya ku Mexico (Cambarellus mantezumae), yotchedwanso Montezuma dwarf crayfish, ndi ya kalasi ya crustacean.
Kufalikira kwa khansa yaing'ono yaku Mexico
Amagawidwa m'matupi a Central America, omwe amapezeka ku Mexico, Guatemala, Nicaragua. Mtundu uwu umapezeka ku Mexico konse, amakhala ku Lake Chapala m'boma la Jalisco, kum'mawa m'nyanja ya Pueblo, mumtsinje wa Xochimilco, pafupi ndi Mexico City.
Zizindikiro zakunja za khansa yaing'ono yaku Mexico
Nsomba zazing'ono ndizosiyana ndi mitundu ina ya nkhanu zazing'onozing'ono. Kutalika kwa thupi lake ndi masentimita 4 mpaka 5. Mtundu wa chivundikiro cha chitinous umasiyanasiyana ndipo umakhala ndi utoto wa imvi, bulauni komanso bulauni.
Chikhalidwe
Nsomba zazinkhanira za Pygmy zimapezeka m'mitsinje, m'nyanja, m'malo osungira ndi ngalande. Amakonda kubisala pakati pa mizu ya zomera za m'mphepete mwa nyanja pakuya kwa mita 0.5. Amapezeka mambiri m'malo ena, ngakhale kulima carp m'minda ya nsomba kumakhudza kuchepa kwa nkhandwezi, koma sikuwopseza kwambiri.
Matenda a khansa ya ku Mexico
Nkhanu zazing'onozing'ono za ku Mexico zimadya zomera zam'madzi, zinyalala zonyansa, ndi mitembo ya nyama zam'mbali.
Kubalana kwa nsomba zam'madzi za ku Mexico za pygmy
Nsomba zazing'ono zazing'ono zimaswana kuyambira Okutobala mpaka Marichi Mkazi aliyense amaikira mazira 12 mpaka 120. Kutentha kwamadzi, pH ndi mpweya wa oxygen sizikhala ndi tanthauzo lililonse pakukula. Moyo wokwanira: kuchuluka kwa oxygen kuchokera pa 5 mpaka 7.5 mg L-1, acidity mu pH osiyanasiyana a 7.6-9 ndi kutentha 10-25 ° C, osapitilira 20 ° C.
Mbalame yotchedwa crayfish ya ku Mexico akuti ndi mitundu yololera thupi. Ma crustaceans achichepere ndi abuluu wonyezimira, kenako amatha kusungunuka ndikupeza mtundu wa achikulire.
Zifukwa zakuchepa
Nsomba zazing'onozing'ono za ku Mexico zimakololedwa pafupipafupi, koma palibe umboni wosonyeza kuti kugwira kumakhudza kwambiri kuchuluka kwa anthuwa.
Kuchepa kwa chiwerengero cha anthu kumawonedwa m'matupi osazama amadzi, pomwe madzi amawinduka ndikuwonjezeka motero kuwala kumafunikira kuti macrophytes aberekenso amachepetsa. Ulimi wa carp amathanso kuyambitsa kuchepa kwamadera m'malo angapo. Izi zimachitika pang'onopang'ono ndipo sizimawopseza kukhalapo kwa mitundu yonseyo, chifukwa chake, njira zodzitetezera sizigwira ntchito ku nsomba zazinkhanira zaku Mexico.
Kusunga nsomba zazing'ono zazing'ono mu aquarium
Crayfish ya Pygmy ndi yamtundu wa thermophilic crustacean. Anthu amtunduwu amakhala m'madzi otentha komanso nsomba zachilendo zomwe zimakhala momwemo. Odyetsa akhala akupanga mitundu yayikulu ya nkhanu zazing'ono. Ali ndi lalanje kapena mtundu wofiira wamtundu wofanana; palinso anthu omwe ali ndi mikwingwirima yotchulidwa. Mtundu wa chivundikiro cha chitinous chimadalira kapangidwe ka madzi ndi chakudya.
Kuti nsomba zazing'ono zazing'ono zizigwidwa, muyenera kukhala ndi aquarium yokhala ndi malita 60 kapena kupitilira apo ndi nthaka, zomera, momwe kusefera kwamadzi ndi aeration yogwira ntchito zimakhazikitsidwa. Nthaka imatsanulidwa osachepera 6 cm kutalika, nthawi zambiri miyala yaying'ono (0.3 - 1.5 cm), miyala ya mitsinje ndi nyanja, zidutswa za njerwa zofiira, dongo lokulitsa, dothi lochita kupanga zam'madzi ndizoyenera.
Mwachilengedwe, nsomba zazinkhanira zazing'ono zimapeza pobisalira, chifukwa chake m'madzi am'madzi amabisala m'mabowo okumba kapena m'mapanga.
Zomera zokhala ndi mizu yotukuka zimayikidwa mu chidebecho: Echinodorus, Cryptocorynes, Aponogetones, mizu yazomera zam'madzi zimalimbitsa nthaka ndikuletsa maenje kuti asagwere. Zipinda zapangidwe zimayikidwa: mapaipi, matabwa oyenda, kudula kwa macheka, zipolopolo za coconut.
Zochita za aeration komanso kuchuluka kwa kusefera kwamadzi zimadalira kukula kwa aquarium ndi kuchuluka kwa ma crustaceans. Madzi am'madzi am'madzi am'madzi amasinthidwa kamodzi pamwezi, ndipo gawo limodzi mwa magawo anayi kapena asanu amadzimadziwo ndi omwe amathiridwa. Kupezeka kwa madzi oyera kumakhudza kuberekanso kwa zamoyo zonse zam'madzi zomwe zimakhala mu aquarium. Izi zimachepetsa kuchuluka kwa zinthu zovulaza ndikuwonjezera mpweya wokwanira wofunikira pamoyo waomwe akukhala m'madziwo. Mukakhazikitsa nsomba zazinkhanira zaku Mexico, madzi amasungidwanso ndi hydrochemical, ndipo mndende, zomwe zimaperekedwa m'malangizowo, zimakwaniritsidwa.
Nsomba zazing'ono zazing'ono sizimakakamira kwambiri kuti mchere ukhale m'madzi. Mitundu yambiri yazinkhanira imakhala m'madzi ndi kutentha kwa 20 ° -26 ° C, pH 6.5-7.8. Madzi okhala ndi mchere wambiri wamchere sakhala oyenera kukhalamo, chifukwa chilengedwe chosungunuka ndikusintha chivundikiro cha chitinous chimasokonekera.
Crayfish yaying'ono imapewa kuwala kwa dzuwa; m'matumba achilengedwe amakhala otakataka usiku. Madzi a m'nyanja omwe ali ndi nsomba zazinkhanira amakhala ndi chivindikiro kapena pepala lophimba. Nyama zam'madzi nthawi zina zimachoka m'madzi ndikufa opanda madzi. Crayfish yaing'ono imadya zakudya zosiyanasiyana, imadyetsedwa ndi chakudya cha nsomba.
Amanyamula nyama, amadya nyama yowonda, maphala am'madzi, kanyumba kochepa mafuta, caviar, mapira opatsa thanzi, amatha kupatsidwa nsomba zatsopano, ma virus a magazi, chakudya chokonzekera nsomba za m'madzi. Ma crustaceans achichepere amatolera zotsalira pansi, idyani mazira ndi nsomba mwachangu, mphutsi. Pachifukwa ichi, ma gastropods amakhala mu aquarium: ma coil ndi nat, nsomba: mollies, pelicia. Mbalame zotchedwa crayfish za ku Mexico zimakhala ndi chakudya chochepa tsiku lililonse. Zotsalira za nsomba zazinkhanira zabisika m'misasa, zimaola patapita kanthawi. Madzi amakhala amtambo, mabakiteriya amachulukana kwambiri mkati mwake, kununkhira kosasangalatsa kumawonekera. Madzi ayenera kusinthidwa kwathunthu, apo ayi zinthu ngati izi zimayambitsa kuphulika kwa matenda opatsirana ndipo khansa imafa.
