Iqembu lokucwaninga eliholwa ososayensi abavela enkabeni yeSayensi uNishin (RNC NISina Center for Accelerator-based Science (RNC), enziwe ngempumelelo kunezinto ezinhle ze-zooplankton, ezisetshenziswa ezinhlanzini zezinhlanzi ngokwenza izinguquko ezinzima. Izingqinamba ezintsha ze-zooplankton zizosiza ukukhulisa ukusinda nokwenza kahle ukukhula kwezinhlanzi e-aquaculture.
Izinhlobo ezibalulekile zezomnotho zezinhlanzi, ezinjenge-tuna eluhlaza okwesibhakabhaka, i-u-e-Japanese u-i-SHARHDDEDER (I-YardStorm), i-Flounder kanye ne-FERRUGE, yokondla izithiyo eziphilayo kuze kube zikhulu ngokwanele ukuba zidle okuphakelayo ngokwanele.
Izivilovu, zibukwa nge-Plankton yezilwane, zivame ukusetshenziswa njengokuphakelayo komthombo. Kodwa-ke, njengoba ikhula, inhlanzi idinga isisekelo sokuphakelayo esandayo, kepha ama-proofrs amancane awakwazi ukukuqinisekisa, okuholela kuma-anomalies wokukhula kwezinhlanzi ngisho nakuma-cannibalism.
"Sinqume ukudala amaphutha amakhulu asebenzisa isipiliyoni sethu nolwazi lwethu ukwenza lula ukuqiniswa kwemali etholwayo evela e-aquaculture," kusho uTomoko Abe eRenc, umholi ocwaningweni.
Ngokubambisana ne-ejensi yaseJapan yocwaningo nemfundo emkhakheni wezokudoba kanye neNyuvesi yaseNagasaki, iqembu lososayensi laqala ukuzama usizo lwendlela eyaziwa ngokuthi yi-iradiation nge-a Ugongolo lwe-athomu esindayo ye-athomu, okubangela ukuguqulwa kwezezimali kahle kakhulu kunezinqubo zemvelo.
Ukulungisa uhlobo lwe-ion nethamo, i-irradiation isetshenziselwa ukunxenxa ukuguqulwa okungahleliwe ku-genome, futhi ungakhetha ama-denotypes afiselekayo. Ososayensi sebevele bakwazile ukuthola ama-microalgae akhiqiza kahle ama-microalgae ahamba phambili, irayisi evutha kakhulu nemvubelo yezentengiso ngendlela efanayo.
Abaphenyi baye balwela ukwanda kwezinkampani ngemishayo ye-argon nama-carbon ion. Ngemuva kwalokho wakhetha abantu abakhulu kunabo bonke futhi batshala iplankton izizukulwane eziningana ukudala umugqa wezinguquko ezinkulu.
Amavoti anikezelwe acishe abe yi-1,2 izikhathi ezingaphezu kwabanye, futhi abe elungele ukondla ngezingane.

Kungenzeka futhi ukuthola izinguquko ezikhula ngokushesha ze-Proplen.
"Ngokuvamile, ukuguqulwa okukhulu kukhula kancane kune-provitratka ejwayelekile, kodwa saba nenhlanhla yokuthola umugqa okhula hhayi omkhulu kuphela, kodwa futhi wakha ngokushesha," kusho u-Abe.
Ukushoda kokudla ngenxa yokukhula kwabantu kuyinkinga enkulu yomhlaba, futhi amazwe emhlabeni jikelele afuna izindlela zokwandisa ukukhiqizwa kokudla.
Ikakhulu, eJapan, njengesifunda esiqhingini, i-aquacilture ibheka indlela ebabazekayo yokuthuthukisa ukuphepha kokudla. Futhi ama-proof allged atholwe kulolu cwaningo anganikeza ukuhlinzekwa okuzinzile kokuphakelayo okubukhoma ngamanani aphansi.
