Isayensi + Ukusebenzisana Kwemboni Kugcina Imboni Ye-Hong Kong Oyster Iphila

ngu-Alexis Valauri-Orton, uMdidiyeli Wohlelo

Emigwaqweni yaseLau Fau Shan, umphakathi omncane osendaweni esenyakatho-ntshonalanga yeNew Territories yaseHong Kong, umoya unuka kamnandi futhi unosawoti. Ngosuku libalele, amakhulukhulu ama-oyster alele phezu kwama-oyster okomisa - izigcawu zedolobha ziguqulwe zaba izimboni zobumnandi obudumile buka-Lau Fau Shan, i-oyster “yegolide” eshiswe ngabomvu. Echwebeni elincane, amabhange kanye namajethi akhiwe ngezitaki zamagobolondo e-oyster.

Eminyakeni emithathu nje edlule ngahamba kule migwaqo, futhi kwabonakala sengathi le mboni yokulima ukhwathu osekuphele amakhulu eminyaka ikhona isengozini yokuwa. Ngangilapho njengengxenye ye-Thomas J. Watson Fellowship eyathatha unyaka wonke, ngifunda ukuthi ukufakwa kwe-acid olwandle kungase kuyithinte kanjani imiphakathi encike olwandle.

UMnu. Chan, omncane kunabo bonke kubalimi be-oyster ngenkathi ngivakashela e-Lau Fau Shan ngo-2012, ume onqenqemeni lwezintanta zoqalo futhi uphakamisa omunye wemigqa eminingi ye-oyster elenga ngezansi.

Ngihlangane nabalimi be-oyster be-Deep Bay Oyster Association. Indoda ngayinye engangixhawula nayo yabelana ngesibongo esifanayo: Chan. Bangitshela ukuthi eminyakeni engu-800 edlule, ukhokho wabo wayehamba obishini lwaseShenzen Bay futhi wakhubeka entweni eqinile. Welula isandla ukuze athole i-oyster, futhi lapho eyivula futhi wathola into emnandi futhi ebabayo, wanquma ukuthola indlela yokwenza ezinye. Futhi kusukela lapho, abakwaChan bebelokhu befuya oyster kuleli chweba.

Kodwa omunye wamalungu asemasha omkhaya wangitshela ngokukhathazeka, “Mina ngiwuthunjana, futhi angicabangi ukuthi kuzoba khona okunye ngemva kwami.” Wangitshela ukuthi eminyakeni edlule ama-oyster abo ayehlaselwa ngokulimala kwemvelo - odayi abavela ezimbonini zezingubo ezikhuphuka nomfula iPearl ngeminyaka yama-80's, okuwusongo oluqhubekayo lwamanzi angahlanzwa. Lapho ngichaza indlela i-acidification yolwandle, ukwehla ngokushesha kwe-pH yolwandle ngenxa yokungcoliswa kwesikhutha, okwakucekela phansi amapulazi ezimbaza e-United States, amehlo akhe avuleka ngenxa yokukhathazeka. Sizobhekana kanjani nalokhu, wabuza?

Lapho ngivakashela e-Lau Fau Shan, abalimi bama oyster bazizwa belahliwe - babengazi ukuthi bangabhekana kanjani nesimo esishintshayo, bengenazo izinto zokusebenza noma ubuchwepheshe bokujwayela, futhi banomuzwa wokuthi abanalo ukwesekwa nguhulumeni. lulama.

Kodwa eminyakeni emithathu yonke into isishintshile. UDkt. Vengatesen Thiyagarajan waseYunivesithi yaseHong Kong useneminyaka efunda imiphumela ye-acidification yolwandle kuma-oyster. Ngo-2013, umfundi wakhe we-PhD, u-Ginger Ko, wasiza ukuhlela i-oyster symposium yokukhangisa oyster basekhaya base-Hong Kong kubafundi nasezifundweni zabo, futhi wamema abalimi baseLau Fau Shan ukuthi beze bazokwethula imikhiqizo yabo.

Ngokukhuthazwa yile workshop, ubambiswano lwaqhakaza. Kusukela kule nkundla yokucobelelana ngolwazi, uDkt. Thiyagarajn, uNksz Ko nabanye baseHong Kong University bahlanganyele nabalimi be-oyster kanye nohulumeni waseHong Kong ukwakha uhlelo lokuvuselela imboni.

Isinyathelo sabo sokuqala ukuqonda izinsongo zemvelo ama-oyster ase-Lau Fau Shan azibekezelela, kanye nokuthuthukisa amasu okubhekana nazo.  Ngosizo loxhaso oluvela ku-Sustainable Fisheries Development Fund, abacwaningi abavela eNyuvesi yase-Hong Kong bafaka uhlelo lokuvala inzalo e-ultraviolet. Uma ama-oyster esekhishiwe e-Deep Bay, azohlala kulesi simiso izinsuku ezingafika kwezine, lapho noma imaphi amagciwane okungenzeka ukuthi awamunce azosuswa khona.

Isigaba sesibili sale phrojekthi sijabulisa kakhulu: abacwaningi bahlela ukuvula indawo yokuchanyuselwa eLau Fau Shan ezovumela izibungu ze-oyster ukuthi zichume endaweni elawulwayo, ngaphandle kosongo lokugcwala kwe-asidi olwandle.

Izisebenzi ze-Deep Bay Oyster Cultivation Association zime ngaphandle kwehhovisi labo e-Lau Fau Shan.

Ngicabanga emuva eminyakeni emithathu edlule. Ngemva kokuba ngitshele uMnu. Chan mayelana nokufakwa kwe-asidi olwandle, futhi ngambonisa izithombe ezivela ekuzaleni okuhlulekile emazinyweni ka-Taylor Shellfish, nganikeza umlayezo wethemba. Ngamtshela ukuthi eWashington State, abalimi be-oyster, abaholi bezizwe, izikhulu zikahulumeni kanye nososayensi babehlangene kanjani ukuze babhekane nokukhuphuka kwe-acidity olwandle - futhi baphumelele. Ngamkhombisa umbiko we-Blue Ribbon Panel, futhi ngakhuluma ngokuthi abaphathi bama-hatchery bawathuthukise kanjani amasu okukhulisa izibungu ngokuphepha.

UMnu. Chan wayengibhekile wayesengibuza, “Ungangithumelela lezi zinto? Ingabe kukhona lapho engeza khona futhi asifundise indlela yokwenza lokhu? Asinalo nje ulwazi noma izinto zokusebenza. Asazi ukuthi senzeni.”

Manje, uMnu. Chan unalokho akudingayo. Ngenxa yokubambisana okukhuthazayo phakathi kweNyuvesi yase-Hong Kong, uhulumeni wasekhaya kanye nabalimi be-oyster base-Lau Fau Shan, imboni eyigugu kanye nomthombo wokuziqhenya okukhulu nomlando uzophikelela.

Le ndaba ibonisa ukubaluleka kokubambisana. Ukube iYunivesithi yaseHong Kong ayizange ibambe lowo mhlangano, ngabe kwenzekani kuLau Fau Shan? Ingabe besiyolahlekelwa enye imboni, omunye umthombo wokudla nemali engenayo, kanye nenye ingqalasizinda eyigugu?

Kunemiphakathi efana neLau Fau Shan emhlabeni jikelele. Kwa-The Ocean Foundation, sisebenzela ukuphindaphinda lokho i-Washington State eyakwazi ukukufeza nge-Blue Ribbon Panel yayo ezungeze i-United States. Kodwa le nhlangano idinga ukukhula - kuzo zonke izifundazwe nasemhlabeni jikelele. Ngosizo lwakho, singakufeza lokhu.
