Kufuneka Uhambe Ngohola wendlela

Le projekthi ixhaswa ngemali nguShark Conservation Fund kunye neNational Geographic Society.

I-smalltooth sawfish sesinye sezidalwa ezintsonkothileyo emhlabeni. Ewe, yintlanzi, kuba bonke ookrebe kunye nemitha igqalwa njengeentlanzi. Ayingokrebe kodwa yiray. Kuphela, inophawu olukhethekileyo oluyahlulayo nakwimitha. Ine "saw" - okanye ngokwemigaqo yesayensi, "i-rostrum" - egqunywe ngamazinyo kumacala omabini kwaye isuka kumphambili womzimba wayo.

Le sarha iyinike umda owahlukileyo. I-smalltooth sawfish iya kudada kwikholamu yamanzi isebenzisa ubundlobongela obuvumela ukuba ibambe ixhoba. Iya kuthi ke ijiwuze ithathe ixhoba layo ngomlomo wayo - othi, njengomtha, uphantsi komzimba wayo. Enyanisweni, kukho iintsapho ezintathu zookrebe kunye nemitha ezisebenzisa iisarha njengezinto zokuzingela. Esi sixhobo sikrelekrele nesisebenzayo sokufuna ukutya siye savela ngamaxesha amathathu ahlukeneyo. 

I-rostra ye-sawfish nayo ibe sisiqalekiso.

Ayisiyonto nje inomdla oye wabonwa kwinkulungwane yeminyaka ziinkcubeko ezahlukeneyo ezifana nophondo lwendlovu okanye amaphiko kakrebe. Neminatha iyabarhintyela ngokulula. Njengoko ingaqhelekanga njenge-sawfish, ayifanelekanga njengomthombo wokutya. I-cartilaginous kakhulu, okwenza ukutsalwa kwenyama ibe yinto engcolileyo kakhulu. Ayizange ibe maninzi kodwa ngoku inqabile kulo lonke uluhlu lwayo kwiCaribbean, i-smalltooth sawfish kunzima ukuyifumana. Nangona kukho amabala ethemba (iinxalenye zolwandle ezifuna ukukhuselwa ngenxa yezilwanyana zasendle kunye neendawo zokuhlala ezibalulekileyo ezingaphantsi kwamanzi) eFlorida Bay kwaye kutshanje eBahamas, kunzima kakhulu ukufumana kwiAtlantiki. 

Njengenxalenye yeprojekthi ebizwa Inyathelo lokuGcina iCaribbean Sawfish (ISCS), Isiseko soLwandle, Abathetheleli bakaShaka bamazwe ngamazwe, yaye ULondolozo loNxweme lwaseHavenworth bazisa amashumi eminyaka omsebenzi kwiCaribbean ukunceda ukufumana olu hlobo. I-Cuba ingumgqatswa ophambili wokuyifumana, ngenxa yobukhulu bayo kunye nobungqina obungenambaliso obuvela kubalobi ecaleni kweemayile ezingama-600 kunxweme olusemantla.

Oosonzululwazi baseCuba uFabián Pina noTamara Figueredo benze uphando ngo-2011, apho bathetha nabalobi abangaphezu kwekhulu. Bafumene ubungqina obubambekayo bokuba i-sawfish yayiseCuba ukusuka kwidatha yokubamba kunye nokubonwa okubonakalayo. Iqabane le-ISCS, uDkt. Dean Grubbs weYunivesithi yaseFlorida State, wayefake i-sawfish ezininzi eFlorida naseBahamas kwaye ngokuzimeleyo wayekrokrela ukuba iCuba ingaba enye indawo yethemba. I-Bahamas kunye neCuba zihlukaniswe kuphela ngumjelo onzulu wamanzi - kwezinye iindawo kuphela iikhilomitha ezingama-50 ububanzi. Ngabantu abadala kuphela abafunyenwe kumanzi aseCuba. Ke, i-hypothesis eqhelekileyo kukuba nayiphi na i-sawfish efunyenwe eCuba iye yafuduka isuka eFlorida okanye eBahamas. 

Ukuzama ukufaka ithegi kwi-sawfish kukudutyulwa ebumnyameni.

Ngokukodwa kwilizwe apho kungekho nanye ibhalwe ngokwesayensi. I-TOF kunye namaqabane aseCuba bakholelwa ukuba ulwazi oluninzi luyafuneka phambi kokuba indawo ichongwe ukuzama uhambo lokumaka. Ngo-2019, uFabián noTamara bancokola nabalobi ababesiya kude eBaracoa, idolophu esempuma ekude apho uChristopher Columbus wafikela eCuba okokuqala ngo-1494. Ezi ngxoxo azivezanga nje iirostra ezintlanu eziqokelelwe ngabalobi kule minyaka idlulileyo, kodwa zanceda ukukhomba indawo ekunokuthegiswa kuyo. malizame. Isitshixo esikwanti seCayo Confites kumantla kumbindi weCuba sikhethwe ngokusekwe kwezi ngxoxo kunye nobubanzi obungaphuhliswanga bengca yolwandle, imango kunye neeflethi zesanti - ezithandwa yi-sawfish. Ngokwamazwi kaGqr Grubbs, oku kuthathwa njenge "sawfishy habitat".

NgoJanuwari, uFabián noTamara bachitha iintsuku bebeka imigca emide kwiphenyane lokuloba elenziwe ngamaplanga.

Emva kweentsuku ezintlanu bengabambisi kwanto, babuyela eHavana bebeke iintloko phantsi. Kuhambo olude olugodukayo, bafumana umnxeba ovela kumlobi wasePlaya Girón kumazantsi eCuba, owalathisa kumlobi waseCardenas. ICardenas sisixeko esincinci saseCuba eCardenas Bay. Njengamabheyi amaninzi kunxweme olusemantla, iya kuthathwa njenge-sawfishy kakhulu.

Ekufikeni kwabo eCardenas, umlobi wabangenisa kwikhaya lakhe waza wababonisa into eyayixaka zonke iimbono zabo. Esandleni sakhe umlobi wayephethe iqonga elincinane, elincinane kakhulu kunayo nantoni na abayibonileyo. Ngenkangeleko yakhe, wayephethe umntwana. Omnye umlobi wayifumana ngo-2019 ngelixa ekhupha umnatha wakhe eCardenas Bay. Okubuhlungu kukuba, intlanzi yasesarha yayifile. Kodwa oku kufunyaniswayo kuya kubonelela ngethemba lokuqala lokuba iCuba inokusingatha abahlali be-sawfish. Isibakala sokuba okufunyenweyo kwakusandul’ ukuvela sasithembisa ngokufanayo. 

Uhlalutyo lwemfuzo lwezicubu zalo mntwana, kunye nezinye iirostra ezintlanu, ziya kunceda ukuhlanganisana nokuba i-sawfish yaseCuba ngabakhenkethi abangenelelayo okanye bayinxalenye yabantu basekhaya. Ukuba le yokugqibela, kukho ithemba lokuphumeza imigaqo-nkqubo yokuloba ukukhusela olu didi kunye nokulandela abazingeli abangekho mthethweni. Oku kuthatha ukufaneleka okongeziweyo njengoko iCuba ingayiboni i-sawfish njengesixhobo sokuloba.

Ibali leCardenas sawfish ngumzekelo wento eyenza ukuba sithande isayensi.

Ngumdlalo ocothayo, kodwa into ebonakala ngathi into encinci efunyenweyo inokutshintsha indlela esicinga ngayo. Kule meko, sibhiyozela ukufa kwe-ray encinci. Kodwa, lo mtha unokunika ithemba koontanga bawo. Inzululwazi inokuba yinkqubo ecothayo. Nangona kunjalo, iingxoxo nabalobi ziphendula imibuzo. Xa uFabián endifowunela ngeendaba wandixelela ukuba, “hay que caminar y coger carretera”. NgesiNgesi, oku kuthetha ukuba kufuneka uhambe kancinci kuhola wendlela okhawulezayo. Ngamanye amazwi umonde, ukuzingisa kunye nokufuna ukwazi okungapheliyo kuya kuvula indlela eya ekufumaneni okukhulu. 

Oku kufunyaniswayo kukuqala, kwaye ekugqibeleni kusenokuthetha ukuba i-sawfish yaseCuba ngabantu abafudukayo. Nangona kunjalo, inika ithemba lokuba i-sawfish yaseCuba ingaba kwinqanaba elingcono kunokuba sasikholelwa.
