Vatsvagiri Vanoona Yakakosha Clue muChakavanzika cheSawfish Mating

Tallahassee, Florida. Kubvumbi 13, 2017. Kekutanga mumakore gumi nemanomwe ekutsvagisa kwakavakirwa kuFlorida, masayendisiti akawana nzvimbo yekusangana yeEndangered smalltooth sawfish.

Ose ari matatu aiva nemavanga akasiyana, sezviri pachena akaitwa panguva yokukwirana, anofanana nepeteni yemazino pamhino dzemhuka dzakaita sesaha.

"Isu tave nenguva tichifunga kuti kusvirana kwemasawfish ibhizinesi rakaoma uye rinodonha, asi isu takanga tisati tamboona kukuvara kutsva kunoenderana nekukwirana kwazvino, kana humbowo hwekuti zviri kuitika munzvimbo dzatakanga tichidzidza senzvimbo dzekuberekesa masawfish," akadaro.

Masayendisiti akatsigira zvavakaona ne ultrasound uye ongororo yehomoni yakaratidza kuti vanhukadzi vaigadzirira kubata pamuviri. Vatsvagiri veFlorida vakabata hove dzechirume nedzechikadzi pamwe chete kashoma, uye munzvimbo shoma.

"Tese tinofara zvikuru nekukura uku mukuedza kwedu kufumura zvisinganzwisisike tsika dzekusvirana dzesawfish," akadaro Tonya Wiley, Muridzi uye Mutungamiriri weHaven Worth Consulting ane makore gumi nematanhatu eruzivo rwekufunda sawfish. “Kunyange zvazvo chikamu chikuru cheSouthwest Florida chakanzi ‘nzvimbo inokosha’ yesmalltooth sawfish, kuwanikwa uku kunosimbisa kukosha kunoshamisa kweEverglades National Park mukuchengetedza uye kupora kwemhuka dzacho.”

Iyo smalltooth sawfish (Pristis pectinata) yakanyorwa sePangozi pasi peESA mu 2003.

"Masowe eFlorida ane nzira refu yekupora, asi kubudirira kunonakidza kusvika parizvino kunopa zvidzidzo uye tariro kune vamwe vanhu vari mungozi pasi rose," akadaro Sonja Fordham, Mutungamiriri weShark Advocates International, chirongwa cheThe Ocean Foundation. "Zvitsva zvakawanikwa zvinogona kubatsira kuedza kuchengetedza sawfish panguva dzakaoma, asi zvakare kusimbisa kukosha kwekuchengetedza nzvimbo yepaki inova nechokwadi chekugara kwakakodzera, mari yekutsvagisa, uye mutemo wakakura waita kuti kubudirira kusvika parizvino kuvepo."
