Ukuqapha okuqhubekayo de peces abafudukayo Ezinhlelweni zemvelo zasemanzini njengoMfula iParaná, ukuqapha sekuthole ukubaluleka eminyakeni yamuva, ikakhulukazi ngenxa yokufakwa kwezinhlelo ze-telemetry ezithuthukisiwe. Lolu hlobo lokuqapha luvumele abacwaningi ukuthi baqonde kangcono imizila efudukayo, impilo yendawo yokuhlala, kanye nezinselelo ezibhekene nezinhlobo ezahlukene zezilwane.
Njengamanje, izinhlangano eziningi, njenge-Itaipú Binacional, Basebenzisa ubuchwepheshe be-PIT (Passive Integrated Transponder). ukulandela umnyakazo de pecesLawa mathegi, afakwe ngaphansi kwesikhumba sezilwane, awanawo amabhethri, njengoba asebenzisa amandla avela ezinkambini zikazibuthe akhiqizwa izimpondo zokulandelela. Ngakho, banganikeza idatha iminyaka., ngaphandle kokuqeda ukuphila kwayo okuwusizo, okuthile okubalulekile ezifundweni zesikhathi eside zemvelo.
Kusukela ngo-2009, ukuqapha kuye kwaqiniswa Ngokumakwa kwezinhlobo ezingaphezu kuka-12.000 zezinhlobo ezingu-42, lokhu kuye kwavumela ukwakhiwa kwamamephu okufuduka kanye nolwazi lwangempela ngezimo zemvelo zezindawo ezinkulu njengamadamu avikelwe uhlaza olukhulu lwezimila.
Esinye sezici ezibalulekile kule nqubo kube ukufakwa kwe izimpondo ezisatshalaliswa eziteshini zokwenziwa -njengePiracema Canal-kanye nezinhlelo ezifanayo ezikhuphuka nomfula, njengasesikhumulweni sikagesi sasePorto Primavera. Ngenxa yalawa madivayisi, kuyenzeka ukurekhoda ukuba khona kwabantu abamakiwe, okubalandele banqamule amakhulu amakhilomitha omfula nemingenela, inikeze umbono onemininingwane eminingi wokuthi bayisebenzisa kanjani indawo ezungezile ukuze baqedele imijikelezo yabo yokuphila.
Izindlela ezifudukayo kanye nomehluko phakathi kwezinhlobo zezilwane
Lapho kuhlaziywa idatha eqoqwe eminyakeni yamuva, kuvela lokho Izinhlobo zibonisa ukuziphatha okuhlukile kokufudukaIsibonelo, kuye kwaqashelwa ukuthi ama-piapara avame ukusebenzisa usebe lomfula omkhulu ukuze azulazule, kuyilapho i-pacús ivame ukukhetha ukungena kwesibili njenge-Piquiri, i-IvaÃ, noma i-Ocoy. Lokhu kwehlukahlukana kwamasu kukhombisa ukubaluleka kokongiwa komfula omkhulu kuphela, kodwa nezindawo zayo ezingenelayo kanye nezindawo ezihlala eduze komfula, ezisebenza njengendawo yokukhosela nezindawo zokuzalela.
Amanye amarekhodi, njengalawo ama-piapara amathathu amakwe futhi akhululwa ngosuku olufanayo, asivumela ukuba sibheke izinto ezicashile emizileni yesikhathi neyokuthutha, lapho umuntu ngamunye engathatha izinyanga ukufinyelela amaphuzu abalulekile njengamapulazi ezinhlanzi noma adlule ezakhiweni ezinkulu zamachibi. Lokhu kuhlola okuningiliziwe kusiza izazi zebhayoloji ukuthi zinqume ukusebenza kahle kwamaphasishi ebhayoloji okwenziwa kanye nokusabela kwezinhlobo zezithiyo ezidalwe abantu.
Imibiko yenkundla ihambisana nocwaningo. Ngokwesibonelo, ukubamba ngezikhathi ezithile de peces Izilwane ezimakiwe ezikude nezindawo zokukhishwa futhi ngaphandle kokudlula ezintini zamashaneli avamile ziphakamisa imizila engalindelekile, njengokudlula kumaturbine asebenza ngamanzi, okuphakamisa imibuzo emisha ngokusinda nokuzivumelanisa nezimo kwalezi zilwane.
Umthelela wokuqapha ekuphathweni kwemvelo kanye nezinselelo zesikhathi esizayo
Ulwazi olutholakala ngalezi zindlela Kubaluleke kakhulu ekuphathweni ngendlela eqhubekayo kwamadamu nemifula. Idatha ibonisa ukuthi ingqalasizinda efana ne-Piracema Canal isebenza njengamaphasishi ebhayoloji asebenzayo., okuvumela izinhlanzi ukuba zifuduke futhi ziqedele umjikelezo wazo wokuzala. Ngaphezu kwalokho, ulwazi oluqoqiwe lubalulekile ekuqondiseni izinqubomgomo zokongiwa kwemvelo kanye nokuhlola isimo sezindawo ezihlala emanzini, okusekelwe intuthuko yezobuchwepheshe nokusebenzisana phakathi kwezikhungo zendawo nabadobi.
Lo msebenzi owenziwa amathimba esayensi anomthwalo wemfanelo walezi zinhlelo zokuqapha ubeka isisekelo se-, okuhloswe ngaso ukulondoloza ukuhlukahluka kwezinhlobo zezilwane kanye nokuqinisekisa impilo yemvelo yezinto eziphilayo ezihambisana nengqalasizinda enkulu yamanzi.
Umzamo oqhubekayo ekubukeni de peces Izinhlelo zemifula efudukayo ziyithuluzi elibalulekile, njengoba ziveza kokubili amathuba nezinselele ezibangelwa ukuphathwa kwalezi zinhlelo zemifula eyinkimbinkimbi. Ukugcina ngisho nokwandisa lezi zinhlobo zezinhlelo kubalulekile ukuze kuzuzwe ukulingana phakathi kwezidingo zomuntu kanye nokongiwa kwezilwane zasemanzini.
