Izinhlanzi ze-Asp ziyefana ne-whitefish, kepha azinayo i-adipose fin encane phakathi komsila nomhlane we-dorsal. I-asp inomlomo omkhulu ophela ngaphansi kwamehlo. Ikhula ize ifike kumitha elilodwa ubude futhi isisindo sayo cishe sibe ngu-10 kg.
Incazelo yezinhlanzi ze-asp
Unomzimba ovulekile futhi ominyene kamuva onekhanda elide elicijile, ikakhulukazi ngesiliva ngombala, ngemuva kunombala omnyama-womnqumo noma mpunga oluhlaza okotshani. I-iris iyisiliva, enesiyingi esincanyana segolide esizungeze umfundi kanye nombala ompunga omncane engxenyeni engenhla. Izindebe ziyisilivere, mpunga engxenyeni engenhla; kutholakala izibonelo ezinezindebe ezibomvu ngokugqamile nama-irises. Iphuzu lomhlathi ongezansi liphuma lize lingene ekhefini emhlathini ongenhla.
Ulwelwesi lwebranchial lunamathele kancane ku-isthmus, cishe ngaphansi komphetho ongemuva weso. Lezi zinhlobo zinamazinyo athe xaxa, ahlukaniswe kakhulu, axhumene.
Amaphiko angemuva naka-caudal anempunga, amanye amaphiko asobala ngaphandle kwe-pigment, i-peritoneum isuka kusiliva kuya koku nsundu.
Ungabamba kuphi
I-Asp itholakala emfuleni iRhine nasenyakatho eYurophu. Ukuphila emilonyeni yemifula egelezela olwandle olumnyama, iCaspian kanye ne-Aral, kubandakanya nogu lwaseningizimu. Izinhlanzi zihlanganiswa ngokuqinile ezimweni ezingezona ezendawo zokudoba eBelgium, eNetherlands naseFrance. Imizamo yokugcwala amadamu nge-asp yenziwa eChina nase-Italy.
I-Asp yizinhlobo zemifula ezihlala emiseleni, emithanjeni nasemanzini asezindaweni ezingasemuva. Inhlanzi ichitha ubusika emigodini ejulile, ivuka entwasahlobo, lapho imifula igcwele futhi ingena ezindaweni zokuzalela, ezisemibhedeni yemifula, izindawo ezivulekile zamachibi anomfula omkhulu, futhi ezimweni ezingavamile lapho lezi zindawo zigcwele buthakathaka izimila ezihhadlazekile, njengomhlanga nemihlanga.
I-asp biology yokuzala
Izinhlanzi zihamba zenyuse umfula ukuze zizale kusuka ngo-Ephreli kuya kuJuni. Ukuzalela kwenzeka emanzini ageleza ngokushesha kwi-substrate yesihlabathi noma yamatshe. UCaviar unamathela kugwadle noma izimila ezigcwele amanzi. Ukufukamela kuthatha izinsuku eziyi-10-15, insikazi izalela amaqanda angama-58,000-500,000 ngobubanzi obungu -1.6 mm. I-Asp gazinga ingu-4.9-5.9 mm ubude. Abantu bafinyelela ekuvuthweni ngokocansi eminyakeni engu-4-5.
Okudliwa yi-asp
Le nhlanzi ukuphela kwezinhlobo ezidla izinhlanzi emndenini we-carp. Esigabeni sokuqala sempilo, i-asp izondla ngama-crustaceans, izilwane ze-benthic, izinambuzane zasemhlabeni emanzini, nezibungu zenhlanzi. Ukudla okubaluleke kakhulu kwe-asp yabantu abadala yilokhu:
- mfiliba;
- i-roach;
- izinhlanzi zegolide.
I-asp endala nayo idla izinhlanzi ezingazidli izizukulwane ezincane ngenxa yokuba khona kwameva, njenge:
- ibhakede;
- i-ruff ejwayelekile;
- i-sand goby;
- umbono.
I-Asp nayo iyadla:
- I-European smelt;
- i-stickleback enezinhlaka ezintathu;
- i-gudgeon ejwayelekile;
- chub;
- i-podust ejwayelekile;
- nontokozo.
Inzuzo yezomnotho
I-Asp izingelwa ukudoba kwezemidlalo, kanti izinhlanzi zizuzisa ngokwezomnotho kuphela kubadobi ngabodwana. Ukudoba kwezokungcebeleka kanye nezokuvakasha kudala ukufunwa kokudla, indawo yokuhlala kanye nezinto zokuhamba, ukukhempa, ukuhamba ngesikebhe, ukuhamba ngesikebhe nokunye. Ukuzingelwa kwezemidlalo kwe-asp kuthinta ngokungaqondile imboni yezokuvakasha yasendaweni.
Awekho amapulazi amakhulu okuzalisa lolu hlobo. I-Asp ivunwa e-Iran njengenhlanzi yokudla, kepha yakha ingxenye encane kuphela yokubanjwa.
Umthelela emvelweni
I-Asp ixazululwe ngamabomu emizimbeni yamanzi kusukela ekupheleni kwekhulu lama-20. Izinhlanzi azinawo umthelela omubi ezindaweni ezintsha zokuhlala, azithinti inani labantu bezinhlanzi ezikhona.
Isikhathi esihle sokubamba i-asp
Kulula ukubamba izinhlanzi ngokushesha ngemuva kokuzala kanye nangesikhathi senyanga egcwele lapho i-asp izondla ngenkuthalo. Ngokuvamile, ibanjwa ubusuku nemini, ngaphandle kwenkathi yokuzala.
