Eminyakeni yamuva, i presencia de peces ama-giant kuma-ecosystem ahlukene kukhiqize kokubili ukukhathazeka njengento ethakazelisa ochwepheshe nezakhamuzi. Ubukhulu obufinyelela kwezinye izinhlobo, kungakhathaliseki ukuthi izinhlobo zemvelo ezisengozini noma izilwane eziphilayo ezandayo, zigqamisa ubuthakathaka bezinto eziphilayo zasemanzini kanye nokubaluleka kwesenzo esihlangene ukuze sizivikele.
Nakuba izifunda ezithile zaseYurophu zisaziqhenya ngokubamba izivakashi izinhlobo ezinkulu eziyisakhiwo sodumo ezisengozini, ezinye izindawo zibheke enzima de peces abezizwe esezikhule ngendlela engalawuleki, okunemiphumela emibi ezinhlobonhlobo zezinto eziphilayo zendawo. Kulesi sihloko, sibukeza amaqiniso amabili aphikisanayo: ukuqina kwezinhlanzi zomdabu e-Andalusia kanye nokuhlasela. de peces ama-dorados amakhulu emachibini aseMelika.
I-goldfish enkulu: Abahlaseli abamangazayo abaphazamisa amachibi ase-US
E-United States, i-Fish and Wildlife Service iye yahlaba umkhosi ngokwanda kwe inhlanzi yegolide enkulu -kufika cishe kumakhilogremu amabili- emachibini nasemachibini. Abanikazi abaningi, bekholelwa ukuthi ukuzikhulula kuyindlela ehlukile yokuzigcina emathangini ezinhlanzi, bazilahla endaweni yemvelo ngaphandle kokucabangela umthelela wezemvelo ukuthi bayachukuluza. Lezi zinhlanzi, ezafuywa ngaphezu kwenkulungwane yeminyaka e-Asia, zizalana kalula futhi zibonisa ukuziphatha okubi kakhulu.
Izibonelo ezitholiwe Ezindaweni ezinjengamachibi Amakhulu, aze aqanjwa ngokuthi "ama-megalodon" ngenxa yobukhulu bawo obungalingani. Ukudla kwabo kuhlanganisa amaqanda nezibungu zezinhlobo zendabuko, ezithinta ngokuqondile ukusinda kwezilwane zomdabu. Ngaphezu kwalokho, zinyakazisa inzika njengoba zidla, zigubuzele amanzi, zikhuthaze ukukhula kolwelwe, futhi zinciphise amazinga komoyampilo endaweni ezungezile, okungase kubangele ukufa phakathi kwezinye izinhlobo zezilwane.
Inkinga ibhebhethekiswa yi- ukungabi khona kwezilwane ezidla ezinye ezinkulu ngokwanele ukulawula lezi zibalo kanye nokumelana kwazo nezimo ezimbi, njengokushisa noma ukushoda komoyampilo. Lokhu kuhumusha ikhono elicishe lingenakuvinjwa lokuqoqa izindawo zokuhlala ezintsha. futhi nande ngesikhathi esifushane; kuye kwaba nezimo lapho, ngemva kokuqeda izinkulungwane zabantu, inani labantu liphinde likhule ngonyaka owodwa nje. Kuye kwaphawulwa nokuthi ukuba khona kwawo kungakhuthaza ukuvela kwamagciwane anobuthi, njenge-cyanobacteria, yona imelela ingozi eyengeziwe empilweni yemvelo zamachibi.
Ngakho-ke, iziphathimandla zigcizelela ukubaluleka kokungadedeli izinhlanzi ezifuywayo ziye endle nokukhetha ezinye izindlela ezinomthwalo wemfanelo lapho kudingekile ukuzilahla. ukunwetshwa kwezinhlanzi ezinkulu zegolide Kakade kuwusongo oluqashelwayo ezindaweni ezinkulu zaseNyakatho Melika.
I-giant guitarfish: uhlobo lwendabuko olusonqenqemeni lokushabalala olumelana ne-Andalusia
Ibhekene nokuthuthuka kwabahlaseli, iYurophu iyaqhubeka nokulwela gcina izinhlobo ezinkulu zendabuko, njenge- i-giantfish enkulu -noma isiginci, I-Glaucostegus cemiculus- Lesi silwane, esihlobene nemisebe noshaka, singesinye sezakhamuzi eziyingqayizivele kunazo zonke ogwini lwase-Andalusi, ikakhulukazi eCádiz naseHuelva, emele isiphephelo sokugcina saseYurophu lapho kusekhona abantu abazinzile.
Okwamanje, i I-giant guitarfish isohlwini lwabasengozini enkulu yi-International Union for Conservation of Nature (IUCN). Lesi simo siwumphumela wokudoba ngokweqile, ukucekelwa phansi kwezindawo zokuhlala, kanye nokucindezela kwabantu ogwini. Nokho, ngenxa yokubambisana kososayensi, izinhlangano, kanye nokubandakanyeka kwezakhamuzi, lolu hlobo lwezilwane luyakwazi ukuphila, nakuba ikusasa layo lihlala lingaqinisekile.
Ukuvikelwa kwale nhlanzi enkulukazi yase-Andalusi kugqamisa ukubaluleka kokulondoloza izinhlobonhlobo zezinto eziphilayo zendabuko kanye ukukhuthaza ukuhlalisana ngokuqaphela nemvelo yasolwandleIzenzo ezinjengokuqapha kwesayensi, ukuncishiswa kwezinhlanzi, nokufundisa ngemvelo kuyisihluthulelo sokumisa ukunyamalala kwazo.
Ubukhona obukhulayo be izinhlanzi ezinkulu, kokubili okuhlaselayo kanye nendabuko, kubonisa isidingo sesenzo esihlangene sokuqinisekisa ibhalansi yemvelo yasemanzini nokuvikela ingcebo yemvelo esisayigcina. Izindaba zokuhlasela nokumelana nazo zikhombisa ukuthi, lapho kubhekene nezingozi zemvelo, isibopho kanye nokubamba iqhaza kwezakhamizi kungamathuluzi abalulekile okwenza umehluko.
