Chinese nsomba kumene akukhala?

Auha (kapena Chinese nsomba) - lililonse woimira kotentha nsomba (Percichthyidae) banja, mmodzi mwa anthu ochepa amene amakhala mu madzi abwino. Dzinali amatchulidwa mu epics zosiyanasiyana.

mafotokozedwe

Torso nsomba ali ndi mtundu yowala. Kuwala chikasu flanks silvery. Against maziko awa, ambiri a mawanga akuda ndi specks wa mosiyanasiyana. Kumbuyo waima enaake imvi mtundu. Kuonekera akuda chifukwa malo - Chinese nsomba Auha wakonda kukhala pakati pa miyala ndi zomera za m'madzi, abisalira nyama yake. Chifukwa cha zakudya wake imakhala nsomba yaing'ono, umene mwadzidzidzi iri yofulumira mwa anabisala aja.

Mofanana ndi mdani aliyense, chida chachikulu cha nsomba ndi mano. Iwo anakonza m'mizere mbali zonse. Kumatako chipsyepsye ndi ventral okonzeka ndi spikes. M'litali wamkulu kungakhale kwa masentimita 70, kulemera zimasiyanasiyana makilogalamu 7 mpaka 10.

Kufalitsa ndi malo

Lina Auha opezeka mitsinje ya Republic of China ndi Korea. Mu Russia, moyo makamaka mu dera lonse la Middle Amur, mu makhwawa wake (Ussuri, Songhua Mtsinje) ndi Nyanja Khanka. kudzadzipeza yayekha ku Sakhalin. Apo iye makamaka ndinawona mu kumpoto chakumadzulo kwa gombe la zokoma Lake. Cold phiri mitsinje Chinese nsomba amayesetsa kupewa. Auha amakonda madzi ofunda, kawirikawiri chigumula amabwera mu nyanja yaing'ono floodplain. Pambuyo spawning nsomba anagawira mu mzere Amur ndi madzi madzi. Zonse yotentha iye fattens kulemera, kudya intensively. M'dzinja amasuntha hibernation mu njira ya Amur. Achinyamata ndi akulu amathera kumeneko nyengo yozizira, kutsogolera moyo wongokhala, ndipo kusinza pansi. Ndipo masika lotsatira, pambuyo pa ayezi otaya kamodzinso amakhala mbali.

Biology Auha

Unamwali nsomba Chinese lapeza kuti zaka zisanu ndi moyo, pa nthawi ino nsomba kufika kutalika kwa masentimita 30 mpaka 40.

Spawning Auha amapita m'chilimwe pamene kutentha madzi ukufika +20 ... +26 ⁰S. Pamaso wakudya zovuta, kuthera awononge maola angapo. Caviar chitaya mbali mobwerezabwereza. Nsomba amakhala ndi chonde kwambiri - munthu mmodzi akhoza kulekeza mazira m'ma 160 zikwi pa nyengo ya chilimwe. Aliyense wa iwo atakulungidwa mu dontho mafuta. pofuna kukwaniritsa mazira kumatenga mu ndime madzi kapena pamwamba pake, choncho ankatchedwa pelagic. Mtundu wa spawning kumawonjezera mwayi wa kupulumuka a mitundu. Patapita masiku ochepa mphutsi kutuluka mazira, ndi masabata awiri kenako - ndi mwachangu, amene mwamsanga m'zigawo chakudya. Young posachedwa wayamba kusaka. Timeneti (osachepera 5 mm), koma kukhetsa mwazi kwambiri kulenga kudya mwachangu nsomba zina, koma nthawi zina ngakhale kudya asuweni zing'onozing'ono. Pa yemweyo kukula nsomba zambiri intensively wayamba kuonjezera. Wamkulu zakudya Amakhala makamaka wa sanali chandamale nsomba monga gudgeon, vostobryushka, rudd, bitterling, sazanchik. A chiwerengero chachikulu cha nkhani zake ndi pa mtsinje orca.

Pa kusakasaka ndi, Chinese nsomba mwadzidzidzi limagwira pa nsomba yaing'ono, analanda iwo pamwamba pa dera lokwera, ndiye mwamsanga chimakakamiza, ntchito minofu ya mutu ndi chiswa mu theka nsembe. Chikuonetseratu Auha chakudya akuyamba ku mchira, chifukwa kumwa nsomba mutu mwina kuwononga mdani ndi zina, ndi kuwononga. Malinga ndi mawonetseredwe ake zolusa a Chinese nsomba Pike ayi otsika ndipo ngakhale kuposa iye mu izi.

mphamvu

Chinese nsomba, amene akambidwa kumayambiriro kwa nkhani ino, limatanthawuza kuti ndi mitundu yambiri numerically ang'onoang'ono amene anali kukhala ku Amur. M'zaka khumi zapitazo, pali kwenikweni akutali nthawi. Kuchepetsa kuchuluka kwake chifukwa opanga tima kukakwera pa nthaka spawning malo waukulu, umene zili China. zifukwa zina ndi kuchita ndi imfa ya mphutsi pa kusintha kwa kudya yogwira. Ndi nthawi iyi pali okwanira kuchuluka kwa chakudya. Iwo ndi mphutsi za nsomba zina zimene zimaoneka ina. ng'ombe ambiri amafa nthawi yozizira choyamba. Pa chikucheperachepera kugwa madzi, kuti ndi madzi madzi. A mbali yofunika kwambiri kuchepetsa chiwerengero cha nsomba Chinese ankaimba ndi kuipitsa.

kukhwimitsa chitetezo

Mwatsoka, kuchuluka ichi cha nsomba m'mayiwewa chaka kokha amachepetsa. chifukwa ndi nsomba zoletsedwa mu malo spawning, zimene zinachititsa chakuti yoimba mwabweretsa m'buku Red mogwirizana ndi kuchepa kwa chiwerengero cha mtundu uwu. Igwire pamene nsomba ndi ndodo - infrequent.

Kutetezedwa ndi Chinese nsomba Auha (chithunzi angapezeke mu nkhani iyi) m'madera a nkhokwe ankazindikira kuti zachilengedwe, ena omwe ndithu odziwika bwino, monga Hankaysky ndi Bolonsky. Ndi zambiri za mapangano ndi zibwenzi Chinese chitetezo ndi njira kuonjezera anthu. Umabweretsa zotsatira zabwino.

Akatswiri akukhulupirira kuti lero chiopsezo kutha kwa nsomba Chinese mozungulira ndi Amur mtsinje palibe kwathunthu, ndi kupereka kusamutsa nsomba pa malo wachisanu ndi Red Book. Iwo amakhulupirira kuti n'zotheka kuchira zonse ndi chitsitsimutso cha anthu a nsomba madzi oyera mothandizidwa ndi zoteteza chilengedwe, chilengedwe cha nkhokwe, ntchito ndi anzake Chinese, ndi zina zambiri zinthu zosiyanasiyana.

Amadziwika kuti zaposachedwapa, anthu nawo nsomba, asangokhala kukula nsomba izi amatunga, komanso kuyamba Loyenda madzi a anthu ka oimira, motero kukula m'dera la nsomba zosiyanasiyana. Mwina chifukwa cha pamwamba, zaposachedwapa pa Amur kale okwanira nsomba.

mawanga usodzi

Pakati ndi malire m'munsi wa Amur zabwino nsomba anagwira Chinese. Kodi amakhala kwambiri, choncho ili ndi dera ku Blagoveshchensk kuti Malmyzh. Apa ndi waukulu kuswana pansi mu Russia. Ndipo ngati pamaso pa nsomba zokodwa mu malo awa makamaka Intaneti wa makampani osiyana ndi makampani, zaposachedwapa Auha kunadetsa adayamba kuwonekera kudzadzipeza asodzi yosavuta zofufuzafufuza, kusonyeza kuchuluka pang'ono mu chiwerengero cha nsomba, koma pakali pano yokha m'dera wa Amur beseni.
