Acidification thiab sov ntawm oceans yuav txo qhov kev noj haus zoo ntawm shellfish nyob rau hauv lub neej yav tom ntej, ib txoj kev tshawb kawm tshiab qhia.
Kev tshawb nrhiav pom tias kev hloov kev nyab xeeb yuav muaj kev cuam tshuam rau qhov kev hloov ntawm Marine cov tsiaj, yog li ua rau yav tom ntej, kev nyab xeeb thiab kev nyab xeeb.
Tam sim no, txoj kev tshawb fawb los ntawm cov kws tshawb fawb hauv University of Plymouth hauv Marine qhov kev tshawb fawb pom zoo tias cov hom kev lag luam thiab kev lag luam muaj peev xwm muaj kev noj haus zoo.
Cov ntsiab lus ntawm txoj kev tshawb ntawm Pacific oysters (Magallana oysters) thiab hauv zos plob hav zoov (oyster eaters) pom tau tias qhov kub thiab txias CO2 yuav ua rau kom qis qis dua cov protein, lipid thiab carbohydrate.
Nqa dej yog lub hauv paus ntawm ntau tshaj 15 feem pua ntawm lub ntiaj teb cov tsiaj noj protein, thiab kev lag luam aquaculture yuav xav hloov nws lub hom phiaj uas muaj zog tshaj rau kev hloov kev nyab xeeb thiab tsis yooj yim thuam, cov kws tshawb fawb hais tias.
Cov kws tshawb fawb Dr Anaelle elemasson, ib tus kws kho mob kawm ntawv hauv tsev kawm ntawv tau pom yav dhau los tau pom tias thaum lub sij hawm Physiology ntawm Pacific pob zeb yuav raug cuam tshuam txog kev hloov pauv yav tom ntej, lawv cov kev tsis zoo yuav tsis cuam tshuam rau.
"Yog hais tias lub koom txoos yog los xyuas cov khoom noj khoom haus, nws tseem ceeb heev kom paub cov kev hloov ntawm cov zaub mov zoo thiab cov tsiaj muaj kev pheej hmoo loj," nws said. Peb cov kev tshawb fawb dhau los tau qhia tias cov kev xav tau tshwm sim hauv 2050 thiab 2100 yuav muaj feem cuam tsis zoo. Tab sis qhov tseeb tias Pacific pob zeb, uas tam sim no yog li ntawm 90 feem pua ntawm UK oyster ntau lawm, yuav muaj cuam tshuam rau kev txhawj xeeb. "
Txoj kev tshawb no tau ua los ntawm cov kws tshawb fawb nrog lub tsev kawm ntawv lub chaw rau Marine Biology thiab Ecology (MBERC) thiab pab pawg neeg tshawb xyuas khoom noj khoom haus, kev noj qab haus huv thiab kev noj haus.
MBERC yog ib lub hauv paus hauv kev tshawb nrhiav ntawm lub ntiaj teb rau txoj kev kawm txog cov teebmeem ntawm ntau yam kev nyuab siab rau Marine lub neej thiab ib puag ncig. Cov menyuam kawm ntawv tiav thiab kawm tiav qib siab feem ntau koom nrog qhov kev tshawb fawb no.
Oysters tau raug rau 6 hom sib txawv ntawm dej hiav txwv nyob rau hauv 12 lub lim tiam, txij tam sim no kub thiab CO2 theem kev twv rau ob qho tib si thiab qhov kawg ntawm xyoo pua nce ntxiv.
Ntxiv rau cov kev hloov hauv kev noj haus ntau, cov neeg tshawb xyuas tau pom cov kev hloov tseem ceeb ntawm cov zaub mov tseem ceeb, ntxiv tias cov tooj liab ntxiv hauv Passters Pacific yuav yog ib qho kev txhawj xeeb tom ntej rau cov neeg siv khoom kev ruaj ntseg.
Dr Victor Kuri, tus kws qhia ntawv hauv cov khoom noj khoom haus zoo ntawm lub tsev kawm ntawv, said: "Cov ntses khis yog cov zaub mov thiab cov khoom noj khoom haus zoo tshaj plaws rau cov ntses thiab lwm yam tsiaj txhu vim lawv tsis muaj kev cuam tshuam dab tsi, tab sis lawv qhov kev vam meej yog nyob ntawm lawv cov cwj pwm zoo, nrog rau palatability, Kev ua haujlwm no qhia tau tias yuav tsum tau nkag siab txog kev tshawb fawb tom qab qhov kev pheej hmoo thiab cov qauv siv hauv cov tshuab qwj nplais, uas yuav tsum tau tsim kom muaj lub peev xwm ua tau zoo ntawm kev sau qoob loo thiab kev ua qoob loo.
Dr Antony Knights, associate professor ntawm Marine ecology, ntxiv: "kev nyab xeeb kev hloov thiab loj hlob thoob ntiaj teb yog tso qhov tsis tsim nyog xav tau ntawm cov protein ntau. thiab cov khoom noj khoom haus balanced.Qhov cov kab no muaj peev xwm los ua ib qho kev lag luam zoo rau cov tib neeg, tshwj xeeb tshaj yog, peb cov av piam thaj av ua rau pom tau zoo dua rau kev hloov pauv hloov yav tom ntej dua li dej hiav txwv Pacific. ib qho kev xaiv zoo aquaculture thiab txhawb kev tsim peev nyiaj nyob hauv cov khoom hauv UK.
