Izici nendawo yokuhlala
Into yokuqala edonsa iso lakho ukubukeka: kuyisicaba, ngicabanga ukuthi abaningi babonile flounder esithombeni, lokhu kungenxa yokuthi ungumhlali wezansi. Izinhlanzi azinakho ukubukeka okungajwayelekile kusuka ekuzalweni, ifry yayo iyafana nezinye izinhlanzi ezijwayelekile, futhi kuphela lapho ikhula iqala ukufana nabantu abadala.
Amehlo abo aqale atholakala ezinhlangothini zomzimba, bese iso elilodwa - kwesokudla noma kwesobunxele, kancane kancane lidlulela kolunye uhlangothi, kanti uhlangothi lapho amehlo womabili ahlala khona luba "phezulu" kwezinhlanzi, kanti esinye yisisu, esiba lula futhi sishwabane, ngakho inhlanzi i-flounder amaslayidi njalo ezansi.
Ingaphila ngokujula okungafika kumamitha angama-200, kepha ukujula okunethezeke kakhulu kuyi-10-15 m. Ijografi yale nhlanzi ibanzi impela, ngoba kunezinhlobo ezahlukahlukene zama-flounders - lawo ahlala olwandle lolwandle:
- ulwandle,
- i-turbot,
- ulwandle olumnyama,
- dab;
- kanye nabahlali bemifula - amanzi angenasawoti.
Ukudoba kolwandle nomfula ekubukekeni kwazo azifani kakhulu, zingahluka ngosayizi kuphela, abafowethu basolwandle bafinyelela osayizi abakhulu. Kunecala elaziwayo lapho amatilosi ebamba i-flounder enkulu enesisindo esingamakhilogremu ayi-100 futhi elinganisa cishe amamitha amabili.
Izindawo zokuhlala nazo zihlukile, ulwandle lutholakala kaningi esimweni sezulu esishisayo, olwandle i-Atlantic Ocean, kanti futhi lutholakala naseNyakatho, Mhlophe, Mnyama nakuLwandle Olumhlophe. Umfula futhi uhlala olwandle, kepha ungabhukuda kude ungene endaweni yamanzi emifula, utholakala oLwandle iMedithera, oLwandle Olumnyama nasemifuleni ejwayelekile kubo.
Kutholakala futhi ku-fairway yoMfula iYenisei. Kukhona futhi uhlobo oluhlukile - iBlack Sea flounder, ebaluleke kakhulu kubadobi bezentengiselwano, inekhono lokulingisa, lihola indlela yokuphila yesihlabathi nokuzingela.
Uhlamvu nendlela yokuphila
Njengoba kushiwo ngenhla inhlanzi i-flounder ezansi ebumba indlela yakhe yokuphila. Yize ngokwemvelo i-flounder iyinhlanzi yasolwandle futhi iyisilwane esidlayo, kepha lokhu akuphoqeleli ukuthi isebenze, ithanda ukuzingela ngokuqamekela.
Esithombeni, i-flounder ifihliwe olwandle
Zilala zinganyakazi, uma kunesidingo, zigobhoza esihlabathini nasemhlabathini, ukuzulazula ekunyakazeni okunyakazayo kwenza ukucindezeleka futhi kuvuze inhlabathi ebazungezile, bese ilele emgodini bese inhlabathi ehleliyo imboze umzimba wayo.
Kepha akupheleli lapho inhlanzi ingakwenza khona ukufihla - umzimba wayo unephethini ohlangothini olubonwayo, olungashintsha ukujwayela imvelo, okwenza ingabonakali nakakhulu. Leli khono libizwa ngokuthi ukulingisa kuzo zonke izidalwa, kepha zonke izinhlobo zobugqila zingalisebenzisa, izinhlanzi eziyimpumputhe azikwazi ukushintsha umbala wazo.
Uma kwenzeka kuba nosongo noma ingozi, i-flounder inyuka ngamandla isuke ezansi, iphendukele ohlangothini lwayo bese ukunyakaza okucijile kuyantanta kude nendawo ephephile, bese uphinde ulale ngohlangothi olungaboni bese ucasha
Esithombeni, umfula ugeleza
Ukudla
Etafuleni le-flounder kukhona "izitsha" ezahlukahlukene, ukudla kwalo kuyahlukahluka: iplankton, izimbungulu ezincane, izibungu, kanye nama-crustaceans nama-crustaceans. Angadla nezimfanzi nezinhlanzi ezincane - ngokwesibonelo, i-capelin, uma bebhukuda besondela eduze kwendawo ayecashe kuyo, yize engathandi izinhlanzi ezibabazekayo nezinambuzane ukuthi zivame ukushiya indawo yakhe yokuhlala, ukuze angabi yisidlo sasemini somunye umuntu. Ithanda ukuzingcwaba enhlabathini enesihlabathi, lapho ingazitholela khona ukudla, imihlathi yayo ikwenze kahle lokhu.
Ukuzala kanye nesikhathi sokuphila
Ngenxa yokwehlukahluka kwezinhlobo zezinto eziphilayo nendawo yokuhlala ebanzi, ukuzala kwe-flounder futhi kwenzeka esikhathini esibalulekile, kubanjwa cishe zonke izinkathi zonyaka. Ukuzala kungenzeka kusukela ngoMeyi kuze kufike ebusika, kanti ezinye izinhlobo ze-flounder zizalela ngaphansi kweqhwa. I-subspecies ngayinye yama-flounders inesikhathi esithile sokuzala.
Esithombeni, izinhlanzi ezihamba olwandle
Indlela yokuphila yenza ukuthi i-flounder ibe yisizungu, ngoba kulula ukuzitholela ukudla, kepha lapho kufika isikhathi sokukhiqiza kabusha, izinhlobo ezahlukahlukene ziyahlangana bese zibhidlika. Lokhu kuholela ekuweleni kwezinhlobo eziningana.
I-flounder ifinyelela ebusheni ngeminyaka emi-3 - 4, izinhlobo ezihlukile ziyakwazi ukubeka amaqanda ayizigidi eziyi-100 kuye kweziyi-13. Usayizi wabo omaphakathi ucishe ube imilimitha elilodwa ububanzi, kodwa mhlawumbe eyodwa nohhafu.
Isikhathi sokukhulisa amaqanda sincike ezimweni zezwe nezimo zezulu: esimweni sezulu esishisayo esinamazinga okushisa aphezulu wamanzi, ukukhula kombungu kungenzeka ngosuku, ezindaweni ezingasenyakatho, ukufukamela kungahlala cishe izinyanga ezimbili nengxenye.
Lapho amaqanda ebhukuda mahhala ebugqineni bamanzi, abonakala ngokusobala, kepha njengoba eshona phansi ezansi, aqala ukushintsha. I-Metamorphosis ishintsha ukubukeka kwayo - amaphiko, i-anal ne-dorsal ishintshelwa ezinhlangothini, ezinye izitho zomzimba zinezinguquko ezifanayo.
Amafry aqhamukayo aqala ukufuna ukudla, esigabeni sokuqala adla i-zooplankton, njengoba ukudla kwawo kugcwala ngokwengeziwe, ukubukeka kwenzeka ezinye izinguquko - iso ohlangothini lwesobunxele luye ohlangothini lwesokunene, kanti uhlangothi lwesobunxele luba phansi.
Kwesinye isikhathi izinhlangothi zingakha enye indlela, yingakho izichyyyologists zingakakwazi ukuphendula, kepha kuye kwabonwa ukuthi ukuphambuka okunjalo kokujwayelekile kuvame ukwenzeka emfuleni ogelezayo.
Isikhathi sokuphila sabantu besifazane singafinyelela eminyakeni engama-30 ngaphezulu, kanti abesilisa baneminyaka engama-20-25. Siphetha incazelo ephansi kubalulekile ukuthi uqaphele ukuthi iyiphi le ndlela enkulu yokuziphendukela kwemvelo yokuthuthuka le nhlanzi edlulile, ifunde ukufihla ngokungabonakali ezansi, ukuhlala ezimeni ezahlukahlukene nokuzala kabusha.
Ngeke ubone izinhlanzi ezi-flounder, ngoba akunakwenzeka ukuyidida nomuntu. Uma ubuza umuntu ukuthi uluhlobo luni lwezinhlanzi oluyi-flounder, khona-ke uzothola impendulo ngokushesha - iflethi, iVedic yisici sayo esihlukile. Izinhlobonhlobo zezinhlobo zehlukene zihlukaniswe imindeni eyi-6, eminingi yayo eyasolwandle, okubanjwa kuyo ukuhweba okusakazwa ePacific nase-Atlantic Ocean.
Ukudoba izinhlanzi ngenhloso yokuzijabulisa kuvame kakhulu olwandle olumnyama, olumhlophe, olweMedithera nolweBaltic. Muva nje, isidingo se-flounder sikhule e-United States. Ogwini loLwandle Olumnyama, abantu bale nhlanzi, ngenxa yokudoba okuqhubekayo, lapho ukufunwa kweTurkey kwaholela khona, babola.
