Introduction
Tikamaganizira za nyama zimene zimalemera kuwirikiza kawiri kuposa njovu ya ku Africa, kaŵirikaŵiri timaganiza za nyama zazikulu zakumtunda monga anamgumi kapena njovu iwo eni. Komabe, pali mitundu ingapo ya nsomba zomwe zimatha kukula kuposa njovu. M’nkhani ino, tiona kuti ndi nsomba iti imene ingalemera kuwirikiza kawiri kulemera kwa njovu ya ku Africa ndi kuphunzira zambiri za nyama zochititsa chidwi zimenezi.
Nsomba Zam'madzi Zam'madzi Zazikulu Kwambiri Padziko Lonse
Mbalame yotchedwa Mekong Giant Catfish ndi nsomba yaikulu kwambiri ya m’madzi opanda mchere padziko lonse lapansi ndipo imatha kulemera makilogalamu 600, kuwirikiza kawiri kuposa njovu ya ku Africa. Nsomba zazikuluzikuluzi zimapezeka mumtsinje wa Mekong kum’mwera chakum’mawa kwa Asia ndipo ndi zofunika kwambiri pa chikhalidwe ndi zakudya za m’derali. Tsoka ilo, chifukwa cha kusodza mochulukira komanso kutayika kwa malo okhala, Mbalame Yaikulu ya Mekong tsopano ili pachiwopsezo chachikulu.
Makhalidwe a Nsomba Yaikulu ya Mekong
Mbalame yotchedwa Mekong Giant Catfish imatha kukula mpaka mamita 10 kutalika ndi kulemera makilogalamu 600, zomwe zimapangitsa kuti ikhale imodzi mwa nsomba zazikulu kwambiri zam'madzi padziko lapansi. Nsombazi zili ndi mtundu wotuwa wabuluu komanso mutu waukulu, wosalala wokhala ndi mphuno yotuluka. Amadziwikanso ndi zida zawo zazikulu zokhala ngati ndevu, zomwe amagwiritsa ntchito pozindikira malo omwe amakhala komanso kupeza nyama. Mekong Giant Catfish kwenikweni amadya udzu ndipo amadya ndere, zomera, ndi zomera zina.
Malo okhala ku Mekong Giant Catfish
Mbalame yotchedwa Mekong Giant Catfish imapezeka mumtsinje wa Mekong, womwe umadutsa maiko angapo ku Southeast Asia, kuphatikizapo Thailand, Laos, Cambodia, ndi Vietnam. Nsomba zimenezi zimakonda maiwe akuya okhala ndi mitsinje yothamanga kwambiri ndipo zimasamukira kumtunda kukabereka m’nyengo yamvula. Tsoka ilo, kumanga madamu, kusodza mochulukira, ndi kuwonongeka kwa malo okhala kwachepetsa kwambiri kuchuluka kwa nsomba za Mekong Giant Catfish m'zaka zaposachedwa.
Zowopseza Mbalame Yaikulu ya Mekong
Mekong Giant Catfish tsopano ili pachiwopsezo chachikulu chifukwa cha ziwopsezo zosiyanasiyana. Kumanga madamu pamtsinje wa Mekong kwasokoneza njira zawo zosamukira komanso kutsekereza njira zoberekera. Kupha nsomba mopambanitsa kwachepetsanso kwambiri chiŵerengero chawo cha anthu, chifukwa m’madera ambiri a kum’mwera chakum’maŵa kwa Asia amaonedwa ngati chakudya chokoma. Kuwonongeka kwa malo okhala ndi kuipitsidwanso ndizomwe zimawopseza kwambiri moyo wa nsombazi.
Kuyesetsa Kuteteza Nsomba Zamgulu La Mekong
Ntchito zingapo zoteteza nyamazi zikugwira ntchito pofuna kuteteza nsomba za Mekong Giant Catfish ndi kubwezeretsanso chiwerengero cha anthu. Izi zikuphatikizapo kuyesetsa kuchepetsa kupha nsomba mopambanitsa, kukonza madzi abwino, ndi kubwezeretsa malo awo achilengedwe. Mayiko ena a m’derali akhazikitsanso ziletso za usodzi ndi ziletso pofuna kuteteza nsombazi m’nyengo zoberekera. Komabe, pali zambiri zofunika kuchita kuti zolengedwa zodabwitsazi zikhalebe ndi moyo.
Nsomba Zina Zolemera Kuposa Njovu
Kuwonjezera pa Mphaka Wachimphona wa Mekong, palinso mitundu ina ya nsomba zambiri yomwe imatha kulemera kwambiri kuposa njovu. Ocean Sunfish, yomwe imadziwikanso kuti Mola Mola, imatha kulemera mapaundi 2,200 ndipo ndi nsomba yolemera kwambiri padziko lonse lapansi. Whale Shark, yomwe ndi nsomba yaikulu kwambiri padziko lonse lapansi, imatha kukula mpaka mamita 40 ndipo imalemera mapaundi 40,000. Goliath Grouper, yomwe imapezeka ku Atlantic Ocean, imatha kulemera mpaka mapaundi 800 ndipo ndi nsomba yotchuka kwambiri.
Kutsiliza
Ngakhale kuti nthawi zambiri timaganizira za nyama zazikulu zakumtunda tikaganizira za nyama zomwe zimalemera kwambiri kuposa njovu, pali mitundu yambiri ya nsomba zomwe zimakhala zazikulu kwambiri. Mbalame yotchedwa Mekong Giant Catfish ndi nsomba yaikulu kwambiri ya m’madzi opanda mchere padziko lonse lapansi ndipo imatha kulemera makilogalamu 600, kuwirikiza kawiri kuposa njovu ya ku Africa. Komabe, chifukwa cha kusodza kochulukira ndi kutayika kwa malo okhala, zolengedwa zodabwitsazi tsopano zili pachiwopsezo chowopsa. Tiyenera kuchitapo kanthu kuti titeteze nsombazi ndikuonetsetsa kuti zikukhalabe ndi moyo kuti mibadwo yamtsogolo isangalale.
