Izinhlanzi ezibushelelezi

Enye yezinhlanzi etholakala kakhulu kuzo zonke izilwandle zomhlaba yi- izinhlanzi ze-mullet. Izinhlobo zayo zisabalele kakhulu, ngakho-ke, kuya ngendawo lapho ibonwa khona, ingaba namagama ahlukile ahlukile, ngaphandle kwenhlanzi ye-mullet. Kuyaziwa ngamagama afana no-mujol, muble, mule noma mugil. Igama layo lesayensi ngu I-Mugil cephalus. Oweqembu de peces ama-teleosts kanye ne-oda lama-muljiforms.

Kulokhu okuthunyelwe sizochaza izici, indlela yokuphila nokukhiqiza kabusha izinhlanzi ze-mullet. Ngabe ufuna ukwazi kabanzi ngayo? Ungaphuthelwa!

Izici eziyinhloko

Le nhlanzi inamandla aphakeme kakhulu okumelana nosawoti ophakeme. Lokhu kubizwa ngokuba yinhlanzi ye-euryhaline ne-eurythmus. Into yesibili ukuthi ingamelana namazinga okushisa ahlukahlukene. Ngokuvamile, zonke izinhlanzi zingahlala ziphilile ebangeni elihlukile lamazinga okushisa. Noma kunjalo, izinhlanzi ze-mullet zisekela izinhlobo eziningi. Lo mthamo uba yisinqumo esinqumayo ekwandeni kwawo emhlabeni jikelele futhi uyimbangela enkulu yokwanda kwawo emhlabeni wonke.

Akuyona inhlobo edinga izimo eziningi ezidinga usizo, ngakho-ke impumelelo yayo yokuphila iphezulu impela.. Ingaphila emanzini asuka ku-4,5 degrees aye kwamanye akuma-37 degrees. Le banga lokushisa eliphakeme liyayivumela ukuthi iguquguquke kakhulu lapho ivumelanisa nezindawo ezahlukahlukene. Usawoti nawo unebanga eliphakeme ngokwanele. Ingaphila ngosawoti kusuka ku-0 kuye ku-45 up.

Ikhono lokuzivumelanisa nezindawo ezihlukene nokujula kuhlobene nosayizi wesifanekiso. Izinhlanzi ezibushelelezi ezingaphansi noma ezilingana namasentimitha ayi-7 zivame ukuhlala isikhathi eside emanzini ahlanzekile. Yize bekwazi ukuhlala emanzini ahlanzekile, akuyona indawo ekahle kunazo zonke yokuzala nokukhula kuyo.

Inomzimba ohlangane kahle futhi inezimpiko ezimbili zasemuva, amaphiko we-pectoral nomsila. Amaphiko anosayizi omncane kakhulu uma usiqhathanisa nengqikithi yomzimba. Inezikali ezahlukahlukene futhi umlomo wayo awumkhulu futhi awubizwa njengezinye izinhlobo. Amazinyo aso mancane kakhulu ngosayizi futhi awanayo imicu.

Usayizi nesisindo

Sithola izibonelo ukuthi zinosayizi ohamba phakathi kwamasentimitha angama-30 kuye kwangama-60. Ngokuya ngohlobo ngalunye, sizothola izilinganiso ezahlukahlukene. Kutholakale izibonelo ezingajwayelekile ezinosayizi wamasentimitha ayi-120. Imvamisa zikhula phakathi kuka-3,9 no-6,4 cm ngonyaka. Abesifazane bakhula ngokushesha kunabesilisa. Kokubili ehlobo nasentwasahlobo bathola ukukhula okubonakalayo ngoba amazinga okushisa aphakeme futhi ukudla kugcwele kakhulu.

Mayelana nesisindo, into ejwayelekile kakhulu ukuthi baphakathi ububanzi obuphakathi kuka-1,5 kg ngezinhlobo ezincane noma ezisathuthuka kanye no-8 kg, enkulu kunazo zonke futhi esefinyelele ekuvuthweni.

Umbala wesisekelo ungwevu futhi uvame ukuba mhlophe. Ukuguqulwa kombala kuvela kufomu elehlayo kanti indawo yasemuva iyingxenye emnyama kakhulu yomzimba wonke. Iyakwazi ukufinyelela phakathi kweminyaka engu-4 nengu-16 ubudala, kuya ngezici eziningi. Ingagcinwa futhi ekuthunjweni, yize kujwayelekile, isikhathi sokuphila sifushane.

Indawo nendawo okusatshalaliswa kuyo

Ukukwazi ukuzivumelanisa cishe nanoma yisiphi isimo endaweni yasemanzini, ububanzi bayo bukhulu kakhulu. Iyakwazi ukuqhubeka nokuhlala kuzo zombili izinto eziphila emanzini angenasawoti kanye nasolwandle. Kubhekwa njengezinhlobo zomhlaba wonke, njengoba kungaba ezindaweni eziningi ezahlukene.

Lapho kuvame kakhulu sizokwazi ukuthola izinhlanzi ze-mullet ezilwandle zamanzi asezindaweni ezishisayo nakwezifudumele. Indawo lapho izinhlanzi zizonquma ukuhlala khona kuzonqunywa ezinye zezinto ezibalulekile kubo. Into yokuqala ukuthi ungaba nesikhala esanele ngemifula kanye nohlaza oluningi. Okwesibili ukuthi idinga ogwini ukuze ihlale. Imvamisa zitholakala ekujuleni kwamamitha ayi-120 futhi yile ndlela ezingahamba ngayo ziye emanzini angajulile.

Ngokuphathelene nendawo yayo yokuhlala, sithe isakazwa kabanzi emhlabeni wonke nasezindaweni eziseduze nogu nezimila eziningi. Sigqamisa izibonelo de peces ULisa ohlala eSpain. Singayibona eCatalonia, eValencia naseMurcia, phakathi kweminye imiphakathi.

Ukudla kwezinhlanzi okushelelayo nokuzala kabusha

Phakathi kokudla kwalezi zinkomishi singabona izinketho ezahlukahlukene ezahlukahlukene. Kuyinto yezinhlobo ezi-omnivorous, ngakho udla konke. Umthombo oyinhloko wokudla udoti wemvelo nezinto zokwakha ezintantayo emanzini noma olwandle. Uhlala azi ukuthi yini engatholakala olwandle olugcinwe ku-substrate. Ubulembu obakhiwa olwandle nabo bungadliwa.

Ngokuvamile, ukudla okugcwele kakhulu ekudleni kwakho:

• Izimila zasolwandle, njenge ulwelwe obomvu noma i ulwelwe oluhlaza.
• Ama-crustaceans ahlukahlukene.
• Ama-Nematode nezinye izinhlobo zonyaka.
• I-Zooplankton.

Phakathi kwalezi zinhlobonhlobo, i-mullet iyona ehamba kakhulu.

Manje siqhubekela ekukhiqizweni. Le nqubo ifingqwe ngokuhamba okuhle ngenzalo entsha. Ukuzalela isikhathi eside kunokujwayelekile, uma kuqhathaniswa nezinye izinhlobo, ngenxa yokuthi kufanele zithole indawo ekahle yazo.

Babheka ukuthi indawo engcono kakhulu yiyona ekude kakhulu nokuxokozela futhi lapho ukuphepha okuthile kwamaqanda kungaqinisekiswa khona. Amajolo azala ngezikhathi ezimbili ngonyaka. Owokuqala wenziwa ekwindla kanti omunye ubusika. Bafinyelela ekuvuthweni kwabo ngokobulili beneminyaka emithathu noma lapho befika kubude obungamasentimitha angama-3. Akuzona zonke izinhlanzi ezinamandla okuvuthwa afanayo. Amanye angama-20 cm ubude futhi awakasebenzi ukuzala kabusha.

Babeka amaqanda ayizigidi ezi-0,5 kuya kwezi-2 kowesifazane ngamunye, nokho eziningi zazo azisindi. Amaqanda athatha izinsuku ezimbili kuphela ukuthi achamusele. Izibungu zihlala eduze kombhede lapho amaqanda achanyuselwe khona futhi zondla imfucumfucu eseduze ne-substrate njengoba zikhula futhi zikhula.

Ngiyethemba ukuthi ngalolu lwazi ungafunda kabanzi ngezinhlanzi ze-mullet.
