Zakudya za Crayfish: ndi nsomba ziti zomwe zimagwiritsidwa ntchito podyera m'chilengedwe komanso zomwe zimadyetsedwa mu ukapolo

M'mayiko ambiri (kuphatikiza Russia), nyama ya nkhanu imatengedwa ngati chakudya chokoma. Anthu amasangalala kudya chokoma chimenechi. Koma pali gulu la anthu amene amaona nkhanu kukhala chakudya chokongola kwambiri. Chifukwa cha "kunyansidwa" uku ndi lingaliro labodza la uXNUMXbuXNUMXbzakudya za arthropod iyi.

Ena amakhulupirira kuti nyama zimenezi zimadya zowola ndi zovunda. Koma izi sizowona. M'nkhaniyi tikambirana zomwe nyamazi zimadya.

Ndi nyama yanji imeneyo?

Musanayambe kulankhula za zomwe nsomba za crayfish zimadya, ndi bwino kudziwa anthu okhala m'madzi a arthropod. Nyama izi ndi ya invertebrate crustaceans. Pali mitundu yambiri, kutchula ochepa chabe mwa omwe amadziwika kwambiri:

• European;
• Kum'mawa kwakutali;
• Cuba;
• Florida;
• nsangalabwi;
• Mexico pygmy, ndi zina zotero.

Khansara imafalitsidwa kwambiri m'makontinenti onse. Malo awo okhala ndi mitsinje yamadzi amchere, nyanja, maiwe ndi mathithi ena amadzi. Komanso mitundu ingapo imatha kukhala pamalo amodzi nthawi imodzi.

Kunja, khansa ikuwoneka yosangalatsa kwambiri. Iye watero zigawo ziwiri: cephalothorax ndi pamimba. Pamutu pali tinyanga ziwiri ndi maso apawiri. Ndipo pachifuwacho chili ndi ziwalo zisanu ndi zitatu, ziwiri mwa zikhadabo. M'chilengedwe, mutha kupeza khansa yamitundu yosiyanasiyana kuchokera ku bulauni ndi zobiriwira mpaka bluish-buluu ndi wofiira. Panthawi yophika, ma pigment onse amawonongeka, zotsalira zofiira zokha.

Nyama ya khansa imatengedwa ngati chakudya chokoma pazifukwa. Kuphatikiza pa kukoma kwabwino, ilibe mafuta, chifukwa chake imakhala ndi zopatsa mphamvu zochepa. Kuphatikiza apo, nyama imakhala ndi zinthu zambiri zothandiza. Pali calcium, ayodini, ndi vitamini E, ndipo pafupifupi mavitamini onse a gulu B.

Amadya chiyani?

Mosiyana ndi zomwe anthu ambiri amakhulupirira kuti nsomba za crayfish zimadya zowola, ndizokwanira chosankha mu chakudya. Ndiye nkhanu zimadya chiyani? Ngati zopangira zopangira ndi mankhwala zilipo muzakudya, ndiye kuti arthropod iyi siyikhudza. Nthawi zambiri, anthu okhala m'madamu amakhudzidwa kwambiri ndi ukhondo wa chilengedwe. M'mizinda yambiri, "amatumikira" kumalo osungira madzi. Madzi amene amawalowa imadutsa m'madzi am'madzi okhala ndi nkhanu. Zomwe amachita zimayang'aniridwa ndi masensa ambiri. Ngati madzi ali ndi zinthu zovulaza, arthropods adzakudziwitsani nthawi yomweyo.

Ma crustaceans nawonso ndi omnivores. Zakudya zawo zimakhala ndi zakudya zochokera ku nyama ndi masamba. Koma mtundu wachiwiri wa chakudya ndiwo umafala kwambiri.

Choyamba, adzadya ndere zogwidwa, udzu wa m’mphepete mwa nyanja ndi masamba akugwa. Ngati chakudyachi sichipezeka, ndiye kuti mitundu yosiyanasiyana ya maluwa amadzi, horsetail, sedge idzagwiritsidwa ntchito. Asodzi ambiri anaona kuti nyamakazi zimadya lunguzi mosangalala.

Koma khansa sidzadutsa ndi chakudya cha nyama chiyambi. Adzadya mosangalala mphutsi za tizilombo ndi akuluakulu, mollusks, mphutsi ndi tadpoles. Nthawi zambiri, khansa imatha kugwira nsomba zazing'ono.

Ngati tilankhula za zotsalira zowola za nyama, ndiye kuti izi zimatengedwa ngati muyeso wofunikira. Khansara imayenda pang'onopang'ono ndipo sizingatheke kugwira "nyama yatsopano". Koma pa nthawi yomweyo, nyama akhoza kudya osati kwambiri decomed nyama chakudya. Ngati nsomba zakufa zakhala zikuwola kwa nthawi yayitali, ndiye kuti arthropod imangodutsa.

Koma mulimonse zomera zakudya kupanga maziko a zakudya. Mitundu yonse ya algae, zomera zam'madzi ndi zam'madzi, zimapanga 90% ya chakudya. Zina zonse sizimadyedwa kawirikawiri ngati mutha kuzigwira.

Nyama zimenezi mwachangu kudya kokha mu nyengo yofunda. M'nyengo yozizira ikayamba, amakhala ndi njala yokakamiza. Koma ngakhale m’chilimwe nyamayo sidya kawirikawiri. Mwachitsanzo, mwamuna amadya kamodzi kapena kawiri patsiku. Ndipo yaikazi imadya kamodzi kokha masiku awiri kapena atatu aliwonse.

Kodi nsomba za nkhanu zimadyetsa chiyani zikamaswana ali ku ukapolo?

Masiku ano, nsomba za nkhanu nthawi zambiri zimabzalidwa mongopanga. Kuti muchite izi, minda imapangidwa pamadzi, nyanja zazing'ono kapena kugwiritsa ntchito zida zachitsulo. Popeza cholinga chachikulu cha bizinesi yotere ndikupeza misa yambiri, amadyetsa arthropods ndi chakudya okhala ndi mphamvu zambiri. Amapita kukadyetsa:

• nyama (yaiwisi, yophika ndi zina zilizonse);
• mkate;
• chimanga kuchokera ku chimanga;
• masamba;
• zitsamba (makamaka nkhanu zimakonda lunguzi).

Panthawi imodzimodziyo, chakudya chiyenera kuperekedwa kwambiri kotero kuti chimadyedwa popanda chotsalira. Kupanda kutero, imayamba kuvunda ndipo arthropods amangofa. Monga lamulo, kuchuluka kwa chakudya kuyenera kukhala kosaposa 2-3 peresenti ya kulemera kwa nyama.

Posachedwapa, ambiri anayamba kusunga nyama zimenezi m'nyumba, mu Aquarium. Pankhani imeneyi, funso limabuka: kudya chiyani? Ngati mumzindawu muli malo ogulitsa ziweto, ndiye kuti mutha kugula chakudya kumeneko. Mu zosakaniza zapadera za arthropods pali mavitamini ndi mchere zonse zofunika pa thanzi lawo.

Chabwino, ngati ndizovuta kupeza chakudya, kapena zatha, ndiye kuti mutha kuzidyetsa ndi zidutswa za nkhuku kapena nyama ina, ndere, nyongolotsi ndi lunguzi zomwezo. Popeza nsomba za crayfish zimakhudzidwa kwambiri ndi ukhondo wa chilengedwe, ndikofunikira kuwonetsetsa kuti zotsalira zazakudya sizisiyidwa mu aquarium kwa masiku opitilira awiri.
