Iintlobo zoKrebe eziseMngciphekweni
Ehlabathini, kukho malunga neentlobo ezingama-500 zookrebe, kwaye kwezi, malunga nama-25% asemngciphekweni wokuphela. Ezinye zezona ntlobo zisemngciphekweni ziquka:
- Ukrebe omhlophe (Carcharodon carcharias)
- Hammerhead shark (Sphyrna lewini)
- I-Basking shark (Cetorhinus maximus)
- I-thresher shark (Alopias superciliosus)
- Inkunzi shark (Galeocerdo cuvier)
Ezi ntlobo zihlelwa kumanqanaba ahlukeneyo esoyikiso, ukusuka emngciphekweni ukuya kwingozi enkulu, ngokutsho IManyano yeHlabathi yoLondolozo lweNdalo (IUCN).
Iimbangela zokuhla kwamanani ookrebe
Kukho oonobangela abaliqela abakhokelele ekwehleni kwamanani ookrebe. Ezinye zezona ziphambili ziquka:
1. Ukuloba ngokugqithisileyo: Omnye woonobangela abaphambili bokwehla kwamanani ookrebe kukuloba ngokugqithisileyo. Oku kuquka ukubanjiswa okujoliswe kuko, ukubanjiswa, kunye neempiko zookrebe, apho ookrebe babanjwa ukuze basebenzise amaphiko abo ukwenza isuphu yephiko likakrebe, isidlo esigqalwa njengento etyiwayo kwezinye iinkcubeko.
2. Ukutshatyalaliswa kwendawo yokuhlala: Ukuthotywa nokutshatyalaliswa kweendawo zokuhlala zaselwandle, ezinje ngeingqaqa zekorale kunye neebhedi zengca yolwandle, ngenxa yezinto ezenziwa ngabantu, ezinjengokwakhiwa konxweme, imigodi, kunye nongcoliseko, nako kuchaphazele ngokunzulu abemi bookrebe.
3. Ukutshintsha kwemozulu: Ukunyuka kwamaqondo obushushu bamanzi kunye ne-asidi yolwandle ngenxa yokutshintsha kwemozulu kunokuba neziphumo ezibi kwiindawo ezihlala ookrebe kunye nexhoba, nto leyo eyenza kube nzima kubo ukuba baphile kwaye bavelise kwakhona.
Amanyathelo okukhusela ookrebe
Ukuqinisekisa ukusinda kwezi ntlobo kunye nokunceda ukubuyiswa kwazo, kuyimfuneko ukuphumeza nokukhuthaza amanyathelo olondolozo. Ezinye izenzo eziphambili ziquka:
1. Ulawulo lokuloba: Ukuphumeza imimiselo nezithintelo ekulobeni iintlanzi zookrebe, ukuthintela ukutsalwa kweentlanzi zookrebe, kunye nokwamkela amanyathelo olondolozo kwiindawo ezizalela kuzo kunye nezokutya kuzo kubalulekile ukukhusela ezi ntlobo.
2. Ukudalwa kweendawo ezikhuselweyo: Ukuseka imimandla ekhuselweyo yaselwandle, apho ukuloba kunye nemisebenzi yabantu esongela indawo yokuhlala kookrebe ithintelwe, inokuqinisekisa ukulondolozwa kwemekobume yabo kwaye ibavumele ukuba bavelise kwaye bafumane ukutya ngaphandle komngcipheko omncinci.
3. Uphando kunye nokubeka iliso kubemi: Ukuqhuba uphando kunye nokubeka iliso kumanani ookrebe kunokubonelela ngedatha ebalulekileyo yokuqonda ukuziphatha kwabo, ukusabalalisa, kunye neemfuno zolondolozo.
Indima yemfundo nokwazisa uluntu
Enye yezona zinto zibalulekileyo zokukhusela iintlobo zookrebe ezisengozini kukwandisa ulwazi nemfundo yoluntu. Abantu abaninzi basababona ookrebe njengabanoburhalarhume nabayingozi, nto leyo enegalelo ekuswelekeni kovelwano nenkxaso kwiimfuno zabo zolondolozo.
Ngokufundisa kunye nokwazisa, unokutshintsha indlela abajonga ngayo ookrebe kwaye ukhuthaze abantu ukuba baxhase ukukhuselwa kunye nokugcinwa kwezi zilwanyana zingaqhelekanga.
Ukubaluleka kokukhusela ookrebe
ookrebe kubalulekile ukugcina ulungelelwano lwendalo yaselwandle, njengoko zilawula abemi bezinye iintlobo kwaye ziphelise izilwanyana ezigulayo nezibuthathaka. Ilahleko yookrebe inokuba nefuthe elibi kwi-ikhosistim kwaye ichaphazele ezinye iintlobo zezityalo nezilwanyana zaselwandle.
Kwakhona, ookrebe bane- isakhono esikhulu kukhenketho oluzinzileyo, njengokubukela ookrebe okanye ukuntywila ekhejini, imisebenzi enokuvelisa iingenelo zoqoqosho kuluntu lwasekuhlaleni kunye nokuxhasa ukulondolozwa kwezidalwa.
Ngamafutshane, ukukhusela iintlobo zookrebe ezisengozini yokuphela kubalulekile ukuze kugcinwe ulungelelwano lwendalo yaselwandle kunye nokulondoloza indalo eyohlukeneyo yesi sijikelezi-langa sethu. Kunyanzelekile ukuba kuthathwe amanyathelo angxamisekileyo nokukhuthaza ulwazi nenkxaso yolondolozo lwezi zilwanyana zimangalisayo.
