Umzimba walesi sidalwa esisemanzini (njengoba kuboniswe ku- isithombe se-bersh), inemivimbo eyisishiyagalombili ehambisanayo emnyama futhi inesimo sokhuni olucikene lumbozwe ngezikali ezinamathiselwe kahle, ezincane, ezinamazinga amancane, ezinwelela kancane ezihlathini nasemsileni. Amaphiko ezinhlanzi ezisemhlane ziyizinhlungu ezingamathambo ezixhunywe ulwelwesi. Amazinyo e-bersh alingana futhi acishe alingane ngosayizi.
Izinhlobo
Lezi zinhlobo zezilwane zasemanzini zingezomndeni omkhulu wamaphakethe. IVolzhsky pike perch yigama lesibili le-bersh, kanti abanye baze baphambanise izinhlanzi ezinjalo ne-pike perch.
Lezi zinhlobo ezimbili ziyafana impela, zingabameleli bohlobo olufanayo lwezinhlanzi. Isici esivelele se-bersh ukungabikho kwama-canine abukhali emlonyeni. Ngaphezu kwalokho, izidalwa zasemanzini ezinjalo zinempumulo ebanzi futhi emfushane, amehlo makhulu ngosayizi, nezihlathi cishe azinalutho, zimbozwe ngezikali ezincane.
IBersh - hhayi inhlanzi enkulu kunazo zonke. Kepha yize ubude bayo, ngokwesilinganiso obucishe bube ngu-25 cm, buvame ukufika engxenyeni yemitha, ipherki perch ihlangana nokukhudlwana.

Uhlamvu nendlela yokuphila
AmaBershees akhetha ukuhlala emanzini ahlanzekile. Abathandi ngempela amanzi anosawoti, ngaphandle kokubhukuda olwandle. Ukuhlala emifuleni nasemachibini, bavamise ukuhlala ekujuleni okukhulu (okungenani amamitha ayi-14), eduze naphansi okuyisihlabathi noma okunosilika, bezama ukushiya izindawo ezingcolisiwe, bebazisa kakhulu ubumsulwa bamanzi abahlala kuwo. Ngaphezu kwalokho, lezi zinhlanzi zizwela ngokweqile emazingeni aphansi e-oxygen emanzini.
Ngezinyanga zasehlobo, i-bersh izama ukuthola izindawo lapho kunokudla okwanele khona. Abantu abadala banamathela emibhedeni yemifula ejulile, kulezo zindawo akunzima kubo ukuthola inyamazane abayithandayo.
Futhi gazinga bavame ukuhlala endaweni engasogwini, lapho bathola khona ukudla kweminyaka yabo. Uma lezi zidalwa zingaxakekile zifuna ukudla, zicasha ezansi, phakathi kwamatshe kanye neziqubu, lapho ziphumula khona ngokuthula nangokuthula. Ubusika bersh iya ekujuleni okukhulu.
Izinhlanzi ezinjalo zihlala zigcinwa ezikoleni. Zisebenza kakhulu ngezikhathi zasekuseni nantambama, okuvame ukucatshangelwa ukuthi nini ukubamba i-bersh abathandi balolu hlobo lomsebenzi.
Kubadobi, lezi zinhlanzi bezilokhu ziyizisulu ezifiselekayo, ziyinto yokudoba amateur, kanye nezemidlalo ukudoba eBersha... Ukunambitheka kwenyama yalesi sidalwa sasemanzini kuthe xaxa, kepha kubhekwa njengokudla okumnandi, futhi izitsha ezivela kuso zifakiwe kwimenyu yezindawo zokudlela eziningi ezithandwa kakhulu.
Izikhathi ezinhle kakhulu zokudoba yizinsuku ezifudumele zenyanga yasentwasahlobo, ehlobo nasekwindla. Futhi isikhathi esihle sosuku ngamahora ngemuva kokuphuma kwelanga nangaphambi kokushona kwelanga, okungukuthi, izinkathi zest esebenzayo yale nhlanzi.
AmaBershees asabela ezinhlotsheni eziningi zezingibe. Ama-silicone twisters nawo asetshenziswa. Ukudoba okwe-bersha gear noma yikuphi okusetshenziswayo: izinduku zokuphotha nezinduku zokudoba, ama-donks nama-girders. Lapho udoba le nhlanzi ebusika, kungcono ukusebenzisa induku ene-reel engena ngaphakathi.
Ukudla kweBersh
Le nhlanzi, engohlobo lwe-pike-perch, iyisilwane esidla isikole. Ezinyangeni zasehlobo, izidalwa zasemanzini ezinjalo azishodi ngokudla okuhlukahlukene. Ukudla kwabo kufaka izinhlobo ezingaphezu kweshumi zezinto eziphilayo.
Abantu abakhulayo, ubude babo obungadluli amasentimitha ambalwa, bakhetha iziphungumangathi ze-choromid, ojekamanzi nezibungu. Njengoba i-bersh ikhula, iqala ukudla ama-fry nama-crustaceans.
Futhi abantu abavuthiwe bazingela izinhlanzi, ubude bazo obufinyelela okungenani amasentimitha ayi-10 kepha ukudla kwabo okuyinhloko kufiphele - omele umndeni we-cyprinid, onobukhulu obungu-20 cm.
Ngokucabangela izintandokazi zokunambitheka kwe-bersh, abadobi besimo sezulu esifudumele bavame ukusebenzisa izibungu, imisundu yegazi nezibungu njengezithiyo. Isithiyelo salezi ziminzi singaba ucezu olujwayelekile lwebhekoni noma izinhlobo zokudla zemvelo: ixoxo, isithiyelo esiphilayo, gazinga.
Ubusika bersh ayidingi kudla, kepha esimweni sezulu esibandayo ilele ngaphansi kwezihibe nasemigodini ejulile, yingakho ukudoba ngalesi sikhathi kungaphumeleli ikakhulukazi.
Ku-tulka bersh iphendula kahle, njengoba le nhlanzi encane, engaba ngamasentimitha ayi-10 ngosayizi, iheha ukunaka kwakhe, okwenza kube yithuba elihle kakhulu lokuyisebenzisa njengesithiyelo, esinomphumela wokuba namafutha akhipha iphunga elimangalisayo.
Ukubamba i-bersh ku-sprat - umsebenzi wokugembula impela, futhi into esemqoka lapha ye-angler ukungaphuthelwa isikhathi esifanele. Lapho nje izinhlanzi ezidla ezinye zibhukuda ziye kulesi sibiliboco esihahelwayo bese ziqala ukusibamba, kufika isikhathi sokuba abathandi bezinhlanzi babambe izisulu zabo ngesikhathi.
Ukuzala kanye nesikhathi sokuphila
Ngonyaka wesine wokuphila, ama-bersh akhula aze afike kuma-20 cm futhi avuthwe ngokomzimba kangangokuba akwazi ukuthola inzalo. Ukuhluma kwale nhlanzi kwenzeka emanzini angajulile, lapho amanzi emifuleni efudunyezwa yimisebe yelanga futhi efudumele impela.
Ukukhetha indawo efanelekayo, okungcono kakhulu okungaba yibhange lesihlabathi, i-bersh yakha isidleke, isibeka ezimpandeni zezitshalo ezahlukahlukene zasemanzini. Abantu bobubili ubulili badlala indima ebonakalayo ngesikhathi sokuzala. Abesifazane badlala lo mdlalo, kuthi abesilisa basebenze njengabaqaphi, bavikele abesifazane besitha nasezinhlanzini ezidla ezinye.
Amaqanda eBersh mancane kakhulu ngosayizi, anobubanzi obungadluli imilimitha elilodwa. Banombala ophuzi, futhi isibalo sabo singamakhulu amaningana.
Ezinsukwini ezinhlanu kamuva, izibungu zivela cishe ngesigamu sesentimitha ngosayizi, okuthi ngesonto elilandelayo zikhule, zikhule futhi zidonse ukudla kusuka esikhwameni samaqanda. Njengoba zikhula futhi zifinyelela ekuvuthweni okudingekayo, ziyaqhubeka nokuzondla.
Ngaphansi kwezimo zemvelo, lezi zinhlanzi zivame ukuhlala kuze kube yiminyaka eyisishiyagalombili. UBersh, ohlala emachibini eVolga, lapho izimo zokuphila zibahle kakhulu kubo, bahlala kuze kube yiminyaka eyi-12, efinyelela kuma-60 cm.
Ukuphepha kweBersh
Njengoba ziyizinhlanzi ezingandile, lezi zidalwa zasemanzini, noma kunjalo, zidlala indima enkulu kubantu ngenxa yenani lazo lokudla okunempilo. Inyama yabo iqukethe amaminerali awusizo, amavithamini abalulekile namaprotheni.
Uwoyela wezinhlanzi okufakwa kuwo ingaphakathi le-bersh ubalulekile emzimbeni womntwana okhulayo futhi ulusizo olukhulu kubantu abadala. Ngaphezu kwalokho, lezi zinhlanzi nazo ziyingxenye ebalulekile yomhlaba wezilwane, okuyinani lazo elingangabazeki.
Ukufundwa kwabakhileyo emizimbeni yamanzi kubaluleke kakhulu ngokwesayensi, ikakhulukazi ezimeni lapho isimo semvelo siguquka njalo, futhi kubaluleke kakhulu ukwazi ukuthi abantu abahlala emanzini basabela kanjani kulezi zinguquko, kanye nokukwazi kwabo ukuzivumelanisa nazo.
Umzimba kaBersh, ophendula ukungcola futhi odinga ukugcwaliswa kwamanzi okuphezulu komoya-mpilo, kuvela ukuthi uyaluqonda ushintsho olubi. Ezingavamile ikakhulukazi izidalwa ezinjalo, isibalo sabantu esivele sincane, e-Ural River basin, okuyisizathu sokufakwa i-bersha eNcwadini Ebomvu... Kwezinye izindawo zesifunda sase-Orenburg, isibonelo, eTanshlinsky nase-Ileks, ukudotshwa kwenetha kwale nhlanzi kukhawulelwe kakhulu.
