Into ebingalindelekile iphakamise ukukhathazeka kubadobi basePucusana nasePunta Negra.. Ezinsukwini ezimbalwa ezedlule, kuye kwaphawulwa ubukhona obuphawulekayo be-silverside ne-squid osebeni lwamadokodo, into engavamile ngalesi sikhathi sonyaka futhi eye yadonsa ukunaka kwabo bobabili amatilosi neziphathimandla zendawo.
Omakhelwane abaningana nabadobi basebenzise lesi simo, baqoqa ngokuqondile izibonelo eziboshwe ngezandla zabo, njengoba kuboniswa amavidiyo amaningi abiwe ezinkundleni zokuxhumana. Lokhu inala engazelelwe Inikeze imali yesikhashana kubadobi bezandla, nakuba nayo ikhiqize ukukhathazeka ngekusasa yomsebenzi wokudoba kanye nokuba khona kwezinhlobo zezilwane endaweni.
I-alamu phakathi kwabasebenzi basolwandle mayelana nomthelela ekudobeni kwezandla
UJuan José Siles, umholi wenyunyana yabadobi basePucusana, uzwakalise ukukhathazeka kwakhe ngaphambi kwe ubukhona obungavamile bezikole ezinkulu zama-squid eduze kwedokodo. Ngokusho kukaSiles, ingwane ibonakala njenge izilwane ezidla inyamazane nezilwane ezidla ezinye okuthi, lapho isondela ogwini, ingasongela ukusinda de peces encane njenge silverside kanye ne-pintadilla. Ungakwazi futhi ukubuza mayelana i-giantfish enkulu ukuqonda kangcono lolu hlobo lwezilwane ezisengozini yokushabalala.
«Ekuqaleni kubonakala kuyithuba lokwenza imali esheshayo., kodwa uma isimo siqhubeka, inani lezilwane ezincane, ezibalulekile ekudobeni kwezandla, cishe lizoncipha kakhulu,” kuchaza uSiles.” Lo mholi ugcizelela ukuthi Yini i-boom namuhla ingase ibe ukushoda okukhathazayo emasontweni ezayo uma ukucindezela kwezinhlobo zasogwini kuqhubeka.
Izimbangela ezingenzeka kanye neqhaza lezici zemvelo
Ongoti bezokudoba kanye neziphathimandla baxhumanisa lesi simo izinguquko ezimweni zasolwandle, njengokuhlukahluka okungavamile kwezinga lokushisa nomoya-mpilo, okungaphoqa lezi zilwane ukuba zishiye izindawo zazo ezivamile futhi zifune isiphephelo eduze nogu. I-squid, ikakhulukazi, ivame ukuhlala emanzini ajulile. futhi akuvamile ukuyithola iseduze kakhulu phezulu.
Futhi, ukucindezeleka kwemvelo okubangelwa ukungcola noma i-hypoxia Kuphinde kukhulunywe njengento engase ibangele, njengoba lezi zici zingaphazamisa izinhlanzi futhi zibangele ukuthi zigcine zivaleleke ngaphandle kwezindawo zazo ezivamile. Le phethini ye-strandings irekhodiwe kwezinye izindawo zogu lwasePeru emasontweni asanda kwedlula, okubonisa ukuphindaphinda komkhuba okhathazayo. Kungase futhi kusize ukubukeza ukuthi kanjani Izinguquko ku-ecosystem yasolwandle zithinta izinhlobo ezifana ne-silverside.
Ukufuna ukudla kungesinye sezizathu ezishiwo. Ezindaweni ezine ukugxila okuphezulu de peces amancane noma ama-crustaceans, ingwane ingalandela inyamazane yayo ogwini, ize nezinye izinhlobo ezifana ne-silverside.
Ukusabela kanye nezilinganiso esimweni se-silverside
Umphakathi odobayo uthatha izinyathelo. Ezinsukwini zakamuva, kuye kwabanjwa imihlangano ephuthumayo phakathi kwabadobi neziphathimandla zendawo. ukuchaza izenzo ezidingekayo ukuze kuvikelwe ukudotshwa kwezandla nokuqinisekisa lokho silverside nezinye izinhlobo zendabuko unganyamalali ogwini.
Abadobi ngokwabo bayakugcizelela lokho "izinhlanzi ezincane", lapho uhlangothi lwesiliva luyinkanyezi, Iwukudla kwansuku zonke kwenqwaba yemindeni endaweni. Ukuhlasela kwezingwane kuphoqa abaningi ukuba bacabange kabusha amasu abo okudoba, kuyilapho befuna ukulinganisela okubavumela ukuba basebenzise leli thuba elikhona manje ngaphandle kokubeka engcupheni ikusasa lomkhakha.
Okwamanje, ugu lwasePucusana nePunta Negra lusaqhubeka nokubonisa izinto ezingavamile, ezine-silverside nesquid okutholakala kalula. Ukungaqiniseki mayelana nemiphumela yalesi simo kuhlala kufihlile ngenkathi ochwepheshe beqhubeka nokusihlaziya ngokujula okwengeziwe.
