Cov kws tshawb fawb tshawb pom qhov tseem ceeb hauv kev paub tsis meej ntawm Sawfish Mating

Tallahassee, Florida. Plaub Hlis 13, 2017. Thawj thawj zaug hauv 17 xyoo ntawm Florida-based kev tshawb fawb, cov kws tshawb fawb tau tshawb pom ib qho chaw sib tw rau cov Endangered smalltooth sawfish. Thaum lub sij hawm mus ncig ua si thaum lub Plaub Hlis Ntuj mus rau qhov dej ntiav dej rov qab-lub teb chaws ntawm Everglades National Park, pab pawg tshawb fawb tau ntes, sau npe, thiab tso peb tus neeg laus sawfish (ib tug txiv neej thiab ob tug poj niam) nyob rau hauv ib cheeb tsam yav dhau los paub yuav luag tshwj xeeb tshaj yog cov menyuam yaus sawfish nyob. Tag nrho peb muaj qhov sib txawv lacerations, pom tau tias muaj kev txhawb nqa thaum lub sij hawm mating, uas phim tus qauv ntawm cov hniav ntawm cov tsiaj 'zoo li snouts. Pab neeg no suav nrog cov kws tshawb fawb los ntawm Florida State University (FSU) thiab National Atmospheric and Oceanic Administration (NOAA) uas ua kev tshawb fawb tsis tu ncua tso cai raws li Txoj Cai Endangered Species (ESA) los saib xyuas cov ntses ntses noj qab haus huv.

"Peb tau xav ntev txog sawfish mating yog kev lag luam ntxhib thiab ua lag luam, tab sis peb tsis tau pom ua ntej kev raug mob tshiab raws li kev sib deev tsis ntev los no, lossis ib qho pov thawj tias nws tau tshwm sim hauv thaj chaw uas peb tau kawm feem ntau yog sawfish pupping grounds," said. Dr. Dean Grubbs, Associate Director of Research for FSU's Coastal and Marine Laboratory. "Kev txheeb xyuas qhov twg thiab thaum twg sawfish ua khub, thiab txawm tias lawv ua ua khub lossis sib sau ua ke, yog lub hauv paus rau kev nkag siab txog lawv lub neej keeb kwm thiab ecology."

Cov kws tshawb fawb tau thim lawv cov kev soj ntsuam nrog ultrasound thiab tshuaj ntsuam xyuas cov tshuaj hormones uas qhia tias cov poj niam tab tom npaj rau cev xeeb tub. Cov kws tshawb fawb Florida tau ntes cov neeg laus txiv neej thiab poj niam sawfish ua ke ntawm ob peb lub sijhawm, thiab hauv ob peb qhov chaw.

"Peb txhua tus zoo siab heev los ntawm qhov kev loj hlob tseem ceeb hauv peb txoj kev mob siab los nthuav tawm cov cwj pwm tsis sib xws ntawm sawfish," said Tonya Wiley, Tus tswv thiab Thawj Tswj Hwm ntawm Haven Tsim Nyog Kev Sib Tham nrog 16 xyoo ntawm kev kawm sawfish. "Txawm hais tias feem ntau ntawm Southwest Florida tau raug xaiv los ua 'qhov chaw tseem ceeb' rau cov hniav me me, qhov kev tshawb pom no qhia txog qhov tseem ceeb tshwj xeeb ntawm Everglades National Park rau kev txuag thiab kev rov zoo ntawm cov tsiaj."

Cov ntses me me (Pristis pectinata) tau teev npe raws li Kev Nyab Xeeb hauv ESA hauv 2003. Raws li kev coj noj coj ua ntawm NOAA, cov npe tau ua rau muaj kev tiv thaiv tseemfwv qib siab rau cov tsiaj, tiv thaiv qhov chaw nyob tseem ceeb, cov phiaj xwm rov qab zoo, thiab ua tib zoo tshawb xyuas.

Sonja Fordham, Thawj Tswj Hwm ntawm Shark Advocates International, ib txoj haujlwm ntawm Ocean Foundation tau hais tias "Florida's sawfish muaj txoj hauv kev ntev mus rau kev rov qab los, tab sis qhov kev ua tiav zoo siab txog tam sim no muab cov lus qhia thiab kev cia siab rau lwm cov neeg muaj kev puas tsuaj thoob ntiaj teb," "Qhov kev tshawb pom tshiab tuaj yeem pab kev siv zog los tiv thaiv sawfish nyob rau lub sijhawm tseem ceeb, tab sis tseem hais txog qhov xav tau los tiv thaiv cov chaw ua si uas ua kom muaj chaw nyob zoo, nyiaj txiag rau kev tshawb fawb, thiab cov kev cai lij choj uas tau ua tiav rau hnub no."
