Isimo kanye neminyaka yokuphila kwezimfanzi ezincane kungaba nomthelela omkhulu ngenxa yendlala.Ukuze zilondoloze amazinga azo amandla, ukukhula, nokuphila kahle, la ma-crustaceans amancane adinga ukutholakala kokudla okuqhubekayo.Ukuntuleka kokudla kungase kubangele ukuba babe buthakathaka, ingcindezi, futhi bathambekele kakhulu ekuguleni nezinye izinkinga zempilo.
Lokhu kuhlanganisa ngokungangabazeki kunembile futhi kuhambisana nazo zonke izinto eziphilayo, kodwa kuthiwani mayelana nemininingwane ethile?
Uma sikhuluma ngezinombolo, ucwaningo luye lwembula ukuthi izimfanzi ezincane ezivuthiwe zingaya ezinsukwini eziyi-10 zingadli ngaphandle kokuhlupheka okuningi.Ukulamba isikhathi eside, ngaphezu kokulamba kuso sonke isigaba sokukhula, kungaholela ekululameni okude kakhulu futhi ngokuvamile kube nomthelela omkhulu kuzo.
Uma unentshisekelo ekuzilibaziseni kokugcina izimfanzi futhi ufuna ukwazi ulwazi olujulile, lesi sihloko kumele sifundwe.Lapha, ngizongena emininingwaneni eyengeziwe (akukho fluff) mayelana nokutholwe kokuhlolwa kwesayensi kokuthi indlala ingaba nomthelela kanjani empilweni yezimfanzi, kanye nokuba sengozini yazo yokudla okunomsoco ezigabeni zokuqala.
Indlela Indlala Ebathinta Ngayo Ama-Swarf Shrimp
Isikhathi sokusinda semfanzi encane ngaphandle kokudla singahluka kuye ngezinto ezintathu ezibalulekile, njengalezi:
ubudala be-shrimp,
impilo ye-shrimp,
izinga lokushisa kanye nekhwalithi yamanzi ethangini.
Ukulamba isikhathi eside kuzonciphisa kakhulu impilo yezimfanzi ezincane.Isimiso sabo sokuzivikela ezifweni siba buthaka, ngenxa yalokho, bathambekele kakhulu ekuguleni nasezifweni.Izimfanzi ezilambile nazo zizala kancane noma ziyeke ukuzala.
Indlala kanye Nezinga Lokusinda Kwe Shrimp Yabantu Abadala
Umthelela wendlala nokudla kabusha amandla e-mitochondrial phakathi ne-Neocaridina davidi
Phakathi nocwaningo lwami ngalesi sihloko, ngathola izifundo eziningana ezithokozisayo ezenziwa ngezimfanzi ze-Neocaridina.Abacwaningi baye babheka izinguquko zangaphakathi ezenzeka kulezi zimfanzi phakathi nenyanga ngaphandle kokudla ukuze balinganisele ukuthi kuzozithatha isikhathi esingakanani ukuthi zilulame ngemva kokudla futhi.
Izinguquko ezihlukahlukene zabonwa kuma-organelles abizwa ngokuthi i-mitochondria.I-Mitochondria inesibopho sokukhiqiza i-ATP (umthombo wamandla wamaseli), futhi ibangele izinqubo zokufa kwamaseli.Ucwaningo luye lwabonisa ukuthi izinguquko ze-ultrastructural zingabonwa emathunjini kanye ne-hepatopancreas.
Isikhathi sokulamba:
kuze kube yizinsuku ezingu-7, azikho izinguquko ze-ultrastructural.
kuze kufike ezinsukwini eziyi-14, isikhathi sokuvuselela sasilingana nezinsuku ezi-3.
kuze kufike ezinsukwini ezingu-21, isikhathi sokuvuselela sasingenani izinsuku ezingu-7 kodwa sasisengenzeka.
ngemva kwezinsuku ezingama-24, yaqoshwa njengephuzu lokungabuyi.Kusho ukuthi izinga lokufa liphezulu kangangokuthi ukuvuselelwa komzimba okulandelayo akusakwazi.
Ukuhlola kwabonisa ukuthi inqubo yendlala yabangela ukonakala kancane kancane kwe-mitochondria.Ngenxa yalokho, inqubo yokutakula yahlukahluka ngokuhamba kwesikhathi phakathi kwezimfanzi.
Qaphela: Akukho mehluko obonwe phakathi kwabesilisa nabesifazane, ngakho-ke incazelo iphathelene nobulili bobubili.
Indlala kanye Nezinga Lokusinda Lama-Shrimplets
Izinga lokusinda lama-shrimplet nentsha phakathi nendlala liyahlukahluka kuye ngesigaba sokuphila kwazo.
Ngakolunye uhlangothi, izimfanzi ezisencane (amaphuphu) zithembele ezintweni ezigciniwe ku-yolk ukuze zikhule futhi ziphile.Ngakho, izigaba zokuqala zomjikelezo wokuphila zibekezelela indlala.Indlala ayikuvimbeli izingane ezisachanyuselwa amandla okuncibilika.
Ngakolunye uhlangothi, uma lokho sekuphelile, ukufa kuyanda kakhulu.Lokhu kungenxa yokuthi, ngokungafani nezimfanzi ezindala, ukukhula ngokushesha kwento ephilayo kudinga amandla amakhulu.
Ukuhlola kubonise ukuthi iphuzu lokungabuyi lalilingana:
izinsuku eziyi-16 zesigaba sokuqala sezibungu (ngemuva nje kokuchanyuselwa), kuyilapho sasilingana nezinsuku eziyisishiyagalolunye ngemva kokuqunjelwa okubili okwalandela,
ezinsukwini eziyi-9 ngemuva kokuqhakaza okubili okwalandela.
Endabeni yezibonelo zabantu abadala ze-Neocaridin davidi, isidingo sokudla siphansi kakhulu kunesama-shrimplets ngoba ukukhula nokucwiliswa kulinganiselwe kakhulu.Ngaphezu kwalokho, izimfanzi ezincane ezikhulile zingagcina izinto ezithile ezigciniwe kumaseli e-midgut epithelial, noma ngisho nasemzimbeni okhuluphele, okunganweba ukuphila kwazo uma kuqhathaniswa nezibonelo ezincane.
Ukondla Shrimp Encane
Izimfanzi ezincane kufanele zidliwe ukuze ziphile, zihlale ziphilile, futhi zizalane.Amasosha abo omzimba ayagcinwa, ukukhula kwawo kuyasekelwa, futhi umbala wawo ogqamile uthuthukiswa ngokudla okunomsoco.
Lokhu kungafaka ama-pellets e-shrimp, ama-wafers we-algae, nemifino emisha noma e-blanched njengesipinashi, i-kale, noma i-zucchini.
Ukudla ngokweqile, nokho, kungaholela ezinkingeni zekhwalithi yamanzi, ngakho-ke kubalulekile ukondla izimfanzi ngokulinganisela futhi ususe noma yikuphi ukudla okungadliwanga ngokushesha.

Izizathu Ezisebenzayo
Ukwazi ukuthi ama-shrimp angaphila isikhathi esingakanani ngaphandle kokudla kungaba usizo kumnikazi we-aquarium lapho uhlela iholidi.
Uma wazi ukuthi izimfanzi zakho zingahlala isonto noma amabili ngaphandle kokudla, ungenza amalungiselelo kusengaphambili ukuze uzishiye ngokuphepha ngesikhathi ungekho.Ngokwesibonelo, ungakwazi:
yondla izimfanzi zakho kahle ngaphambi kokuhamba,
setha okuphakelayo okuzenzakalelayo ku-aquarium ezobaphakela ngenkathi ungekho,
cela umuntu omethembayo ukuthi ahlole i-aquarium yakho futhi ondle izimfanzi zakho uma kunesidingo.

Ekuphetheni
Ukulamba isikhathi eside kungaba nomthelela omkhulu empilweni yezimfanzi ezincane.Ngokuya ngeminyaka yezimfanzi, indlala inemiphumela ehlukene yesikhashana.
Izimfanzi ezisanda kuchanyuselwa zimelana kakhulu nendlala ngoba zisebenzisa izinto ezigciniwe ku-yolk.Nokho, ngemva kwama-molts amaningana, isidingo sokudla siyanda kakhulu ezimfanzini ezisencane, futhi ziba yizona ezikwazi ukumelana nendlala.Ngakolunye uhlangothi, izimfanzi ezindala yizona ezikwazi ukumelana nendlala.
