Crayfish chikafu: chii crayfish inoshandiswa kudya mune zvakasikwa uye izvo zvavanodyiswa mukutapwa

Munyika dzakawanda (kusanganisira Russia), crayfish nyama inonzi inonaka. Vanhu vanofara kudya chinonaka ichi. Asi kune boka rakadai revanhu vanofunga kuti crayfish haisi chikafu chinonaka. Chikonzero cheichi "kusema" ipfungwa yenhema yeuXNUMXbhuviri hweiyi arthropod.

Vamwe vanodavira kuti mhuka idzi dzinodya zvakaora uye zvakaora. Asi ichi hachisi chokwadi zvachose. Muchikamu chino tichataura pamusoro pezvinodyiwa nemaarthropods aya.

Imhuka rudzii iyoyo?

Usati wataura nezve izvo crayfish inodya, zvakakosha kuziva vagari veArthropod yemvura element. Mhuka idzi ndeye invertebrate crustaceans. Kune marudzi akawanda, kungodoma mashoma eanonyanyozivikanwa:

• European;
• Far Eastern;
• Cuban;
• Florida;
• marble;
• Mexican pygmy, nezvimwewo.

Zvirwere zvegomarara zviri kuparadzirwa zvakanyanya kumakondinendi ese. Nzvimbo yavo inogara nzizi dzine mvura yakachena, madziva, madziva nemimwe miviri yemvura. Uyezve, marudzi akati wandei anogona kugara munzvimbo imwe kamwechete.

Kunze, gomarara rinotaridzika kunakidza. Akazviita zvikamu zviviri: cephalothorax uye dumbu. Mumusoro mune mapeya maviri emaziso uye maziso akakomberedzwa. Uye chipfuva chine mapeya masere emakumbo, maviri acho ane nzara. Muzvisikwa, unogona kuwana kenza yemhando dzakasiyana-siyana kubva kune brown uye girini kusvika bluish-bhuruu uye tsvuku. Panguva yekubika, pigments yose inoparara, tsvuku chete inosara.

Nyama yegomarara inoonekwa sechinhu chinonaka nekuda kwechikonzero. Pamusoro pekuravira kwakanakisa, haina kana mafuta, saka ine yakaderera calorie yemukati. Mukuwedzera, nyama ine zvinhu zvakawanda zvinobatsira. Kune calcium, uye iodine, uye vhitamini E, uye anenge ese mavhitaminzi kubva muboka B.

Anodyei?

Kusiyana nedzidziso yakakurumbira yekuti crayfish inodya kuora, ivo vakanaka kusarudza muchikafu. Saka magakanje anodyei? Kana zvigadzirwa zvekugadzira uye zvemakemikari zvinowedzera muzvokudya, saka iyi arthropod haigoni kuibata. Kazhinji, vagari venzvimbo idzi vanonyatsonzwa nekuchena kwenzvimbo. Mumaguta akawanda, “vanoshumira” panzvimbo dzinoshandiswa mvura. Mvura inopinda mavari inopfuura nemu aquariums ine crayfish. Kuita kwavo kunotariswa nemasensor akawanda. Kana mvura ine zvinhu zvinokuvadza, ipapo arthropods ichakurumidza kukuzivisa iwe nezvazvo.

Crustaceans ivo pachavo vari omnivores. Kudya kwavo kune chikafu chezvose mhuka nemuriwo. Asi rudzi rwechipiri rwechikafu ndirwo rwakanyanya.

Chekutanga, achadya algae dzakabatwa, uswa hwemahombekombe uye mashizha akadonha. Kana chikafu ichi chisipo, ipapo marudzi akasiyana-siyana emaruva emvura, horsetail, sedge achashandiswa. Vabati vehove vakawanda vakaona kuti arthropods dzinodya rukato nekunakidzwa.

Asi kenza haizopfuuri nechikafu chemhuka. Iye achafara kudya zvipembenene zvipembenene uye vanhu vakuru, mollusks, honye uye tadpoles. Kashoma, kenza inokwanisa kubata hove diki.

Kana tikataura pamusoro pekuora kwakasara kwemhuka, zvino izvi zvinonzi chiyero chinodiwa. Kenza inofamba zvishoma nezvishoma uye hazviiti nguva dzose kubata "nyama itsva". Asi panguva imwecheteyo, mhuka inogona kudya chete kwete zvakare yakaora chikafu chemhuka. Kana hove dzakafa dzave dzichiora kwenguva yakareba, ipapo arthropod inongopfuura.

Asi zvakadaro zvirimwa zvekudya zvinoumba hwaro hwekudya. Mhando dzese dzealgae, zvirimwa zvemumvura uye zvemumvura, zvinosvika makumi mapfumbamwe muzana ezvekudya. Zvimwe zvese hazviwanzo kudyiwa kana ukakwanisa kuzvibata.

Mhuka idzi dzinoshingaira kudya chete mumwaka wekudziya. Nekutanga kwechando, vane nzara yekumanikidza. Asi kunyange muzhizha mhuka haidyi kakawanda. Somuenzaniso, murume anodya kamwe kana kaviri pazuva. Uye hadzi inodya kamwe chete mazuva maviri kana matatu oga oga.

Chii chavanodyisa crayfish pavanenge vachiberekera muusungwa?

Nhasi, kazhinji crayfish inorimwa zvisirizvo. Kuti uite izvi, mapurazi anogadzirwa pamadziva, madhamu maduku kana kushandisa midziyo yesimbi. Sezvo chinangwa chikuru chebhizimisi rakadaro ndechokuwana hukuru hukuru, vanodyisa arthropods nechikafu ine simba rakawanda. Inoenda kunodyisa:

• nyama (yakabikwa, yakabikwa uye chero imwe fomu);
• chingwa;
• zviyo kubva muzviyo;
• miriwo;
• herbs (kunyanya crayfish inoda nettles).

Panguva imwecheteyo, chikafu chinofanira kupihwa zvakanyanya zvekuti chinodyiwa pasina chasara. Zvikasadaro, inozotanga kuora uye arthropods inongofa. Sezvo mutemo, huwandu hwekudya hunofanira kunge husina kupfuura 2-3 muzana yehuremu hwemhuka.

Munguva pfupi yapfuura, vazhinji vakatanga kuchengeta mhuka idzi mumba, mu aquarium. Panyaya iyi, mubvunzo unomuka: chii chokudyisa? Kana pane pet store muguta, ipapo unogona kutenga zvokudya ikoko. Mumisanganiswa yakakosha yearthropods kune ese mavhitamini nemamineral anodiwa kune hutano hwavo.

Zvakanaka, kana zvakaoma kuwana zvokudya, kana kuti zvapera, unogona kuzvidyisa nezvimedu zvehuku kana imwe nyama, algae, earthworms uye zvese zvakafanana. Sezvo crayfish inonyanya kukoshesa kuchena kwezvakatipoteredza, zvinodikanwa kuve nechokwadi kuti zvakasara zvekudya hazvina kusiiwa mu aquarium kwemazuva anopfuura maviri.
