Ukukhishwa okusha kwe i-fartet fish (Aphanius iberus) endaweni yemvelo yomlomo we- Guadalhorce River, ngokuqaliswa kabusha kwe Amakhophi we-350 kusukela ku-Center for Breeding and Conservation of Endangered Fish (CECCPA) e-Los Villares, Córdoba.
Isenzo, esikhuthazwa uMnyango Wokusimama Nemvelo, sifuna qinisa ukuhlukahluka kofuzo futhi uhlanganise i-nucleus efaneleka kakhulu yalolu hlobo lwezilwane e-Andalusia, ngokubambisana naleyo I-Adra Lagoon, kubazali boyedwa inani labantu base-Andalusian bemvelo etholakala emfuleni i-Adra (AlmerÃa).
Ukufakwa kabusha endaweni yaseGuadalhorce
I-Malaga enclave, ye imvelaphi yokwenziwa kodwa enenani elikhulu Mayelana nezinhlobonhlobo zezinto eziphilayo, iyikhaya lamanzi amaningana anosawoti oshintshashintshayo kuye ngemvula kanye ne-akhwifa yasogwini, ehlinzeka ngendawo ekahle yohlobo lwezilwane ngezikhathi ezahlukene zonyaka.
Kusukela ngo-2017 bakhishwe kulesi sikhala ezingaphezu kuka-5.200 fartets, ukudala i-macronucleus ku ichibi elikhulu futhi, ngokwezinga elincane, ku umfula omdala. Ukukhishwa okuvamile kugweme ukuvinjelwa kofuzo futhi kube negalelo ekulondolozeni abantu abaphilayo ngaphansi kwezimo zemvelo ezishintshayo.
Inzuzo yemvelo kune-gambusia
I-fartet ibonakala ngokumelana kwayo okuphezulu izindawo ze-hypersaline kanye namazinga okushisa aphezulu, okuyivumela ukuthi iqhudelane nenzuzo ngokumelene nezinhlobo ezihlaselayo I-Gambusia (Gambusia holbrooki)Ngenkathi i-gambusia ingakubekezeleli usawoti ongaphezulu 35-37 g/L, i-fartet ingakwazi ukumelana nokugxila okufika ku 140 g / L.
Ingcindezi ye Gambusia ngokomlando isuse i-fartet yayisa ezindaweni eziseceleni; kodwa-ke, izindawo zokuhlala ezinosawoti omningi we- Guadalhorce thanda izinhlobo zomdabu, inkinga ngezinye izikhathi eholela e ukuqedwa kwenhlanzi ehlaselayoEhlobo, iziqephu ezithile ze i-eutrophication kanye nokuntuleka kwe-oxygen ezindaweni ezimile, ngakho-ke kwenziwa umsebenzi wokuthuthukisa izinga lamanzi.
Imibandela yesayensi nezigaba zomsebenzi
Ukwethulwa kabusha kulandela imihlahlandlela ye IUCN, ukubeka phambili izindawo zamanzi lapho ubusawoti bukhawulela ukwanda komhlaseli futhi kuthuthukisa umncintiswano we-fartetLokhu kukhethwa kwendawo yokuhlala kusekelwa ukuhlaziywa kwe-physicochemical kanye nokuqapha okuqhubekayo kobuchwepheshe.
Uhlelo luqale ngokuhlanganisa a ukusungula i-nucleus echibini likagamthilini futhi, lapho isizinzile, yandisa ukuba khona kwezinhlobo zezilwane ngasemanzini. enyakatho yomfula omdala, ukwandisa inani lamaphuzu anemibandela efanelekile.
Phakathi kwezinyathelo zokuphatha, ithimba lifunda i ukulawulwa kweminikelo evela emfuleni iGuadalhorce ukuzinzisa usawoti omningi, ngaphezu kokuqinisa izimila zasemanzini kanye nokuqinisekisa izindawo zokukhosela ezingasogwini ezithuthukisa indawo yokukhosela kanye nokuzala.
Izinselele nezinyathelo ezilandelayo
Izinselelo ezifana ne Ukulawula kweGambusia Emachibini athile, kunezimpawu zokujwayela usawoti ophakeme kunalawo arekhodiwe esikhathini esidlule, okudinga ukulungisa izenzo zokuphatha.
Impumelelo yesikhathi esizayo idinga a umbono wesikhathi eside ngokusekelwe ocwaningweni, ukuqapha okuqhubekayo kanye nokuxhumana phakathi kweziphathimandla, izikhungo zokuzalanisa kanye nabasebenzi bezobuchwepheshe, umsebenzi wabo ube ukhiye ekugwemeni izingqinamba zofuzo futhi kugcine isibalo sabantu.
Ngaphezu kwesimo sayo njengesilwane esisengozini, i-fartet idlala a umsebenzi wemvelo ewusizo: kunomthelela ekulawuleni okungokwemvelo kwe izibungu zomiyane, enemiphumela emihle ezindaweni zasemadolobheni eziseduze phakathi nezinyanga ezifudumele.
Ngalokhu kukhishwa okusha kwe Amakhophi we-350, Uhlelo lweBhodi luthuthuka ekuhlanganisweni kwefartet ku Guadalhorce, esekelwa imibandela yesayensi, ukuphathwa okuguquguqukayo kanye nenethiwekhi yokuhlanganyela esevele ivumele ukwethulwa kabusha abantu abangaphezu kuka-5.200 kusuka ku-2017.
