Eminyakeni embalwa edlule, ngibhale izihloko eziningi mayelana nezimfanzi ezincane (Neocaridina kanye neCaridina sp.) nokuthi yini ethinta ukuzala kwazo.Kulezo zihloko, ngikhulume ngomjikelezo wabo obukhoma, izinga lokushisa, isilinganiso esifanele, imiphumela yokukhwelana njalo, njll.
Nakuba ngifuna ukungena emininingwaneni kuzo zonke izici zempilo yabo, ngiyaqonda futhi ukuthi akubona bonke abafundi abangachitha isikhathi esiningi bezifunda zonke.
Ngakho-ke, kulesi sihloko, ngihlanganise ulwazi oluthakazelisa kakhulu noluwusizo mayelana nezimfanzi ezincane kanye namaqiniso okuzalanisa ngolwazi olusha futhi.
Ngakho-ke, qhubeka ufunda ukuze wazi kabanzi, lesi sihloko sizophendula imibuzo yakho eminingi.
1. Ukukhwelana, Ukuchanyuselwa, Ukukhula kanye Nokuvuthwa
1.1.Ukukhwelana:
Umjikelezo wempilo uqala ngokukhwelana kwabazali.Lokhu kufushane kakhulu (imizuzwana embalwa nje) futhi inqubo engase ibe yingozi kwabesifazane.
Iphuzu liwukuthi izimfanzi zesifazane zidinga i-molt (zichithe i-exoskeleton yazo endala) ngaphambi kokuzala, kwenza ama-cuticles azo athambile futhi aguquguquke, okwenza ukuvundiswa kwenzeke.Uma kungenjalo, ngeke bakwazi ukudlulisa amaqanda kusukela ku-ovary kuya esiswini.
Lapho amaqanda esevundisiwe, izimfanzi ezincanyana zizowathwala cishe izinsuku ezingama-25 - 35.Ngalesi sikhathi, zisebenzisa ama-pleopod (ama-swimmerets) azo ukugcina amaqanda ehlanzekile ekungcoleni futhi enomoya omuhle kuze kube yilapho achanyuselwa.
Qaphela: Izimfanzi zesilisa azibonisi ukunakekelwa kwabazali ngenzalo yazo nganoma iyiphi indlela.
1.2.Ukuchanyuselwa:
Wonke amaqanda achanyuselwa emahoreni ambalwa noma ngisho nemizuzu.
Ngemva kokuchanyuselwa, izimfanzi ezincane (ama-shrimplets) ziba cishe ngo-2 mm (0.08 amayintshi) ubude.Ngokuyisisekelo, angamakhophi amancane abantu abadala.
Okubalulekile: Kulesi sihloko, ngikhuluma kuphela ngezinhlobo ze-Neocaridina ne-Caridina ezinokukhula okuqondile lapho ama-shrimp ezingane akhula abe abantu abavuthiwe ngaphandle kokushintshashintsha.
Ezinye izinhlobo ze-Caridina (isibonelo, i-Amano shrimp, i-Red Nose Shrimp, njll.) zinokuthuthuka okungaqondile.Kusho ukuthi isibungu sichanyuselwa sisuka eqandeni bese sishintsha sibe umuntu omdala.
1.3.Iyakhula:
Emhlabeni wezimfanzi, ukuba mncane kuyingozi enkulu, zingawela cishe yonke into.Ngakho-ke, amaphuphu awanyakazi e-aquarium njengoba kwenza abantu abadala futhi ancamela ukucasha.
Ngeshwa, lolu hlobo lokuziphatha lubenza bangakwazi ukuthola ukudla ngoba abavamile ukuya obala.Kodwa noma bezama, maningi amathuba okuthi izimfanzi zezingane ziphushelwe eceleni abantu abadala futhi zingase zingakutholi nhlobo ukudla.
Izimfanzi zezingane zincane kakhulu kodwa zizokhula ngokushesha.Lesi isinyathelo esibalulekile sokuzisiza ukuthi zikhule zibe zinkulu futhi zibe namandla.
Yingakho kudingeka sisebenzise uhlobo oluthile lokudla okuyimpushana kubo.Kuzokwandisa izinga lokusinda kwazo futhi emasontweni ambalwa, zizoba zikhulu futhi ziqine ngokwanele ukuba zidle noma kuphi lapho zithanda khona.
Njengoba izimfanzi ezisanda kuzalwa ziba zinkulu ziba intsha.Cishe zingu-2/3 wosayizi omdala.Phakathi nalesi sigaba, namanje akunakwenzeka ukuhlukanisa ubulili ngeso lenyama.
Isigaba sokukhula sithatha cishe izinsuku ezingama-60.

● Indlela yokwandisa izinga lokusinda kwama-shrimplets?
● Ukudla Okuphezulu Kwe Shrimp – Bacter AE
1.4.Ukuvuthwa:
Isigaba sobusha siphela lapho uhlelo lokuzala luqala ukukhula.Ngokuvamile, kuthatha cishe izinsuku ezingu-15.
Nakuba kungenakwenzeka ukubona izinguquko kwabesilisa, kwabesifazane singabona ubukhona be-ovary enombala osawolintshi (okuthiwa “iSaddle”) endaweni ye-cephalothorax.
Lesi yisigaba sokugcina lapho izimfanzi ezisencane ziphenduka umuntu omdala.
Bavuthwa ezinsukwini ezingama-75-80 futhi phakathi kwezinsuku ezi-1 - 3, bazobe sebelungele ukukhwelana.Umjikelezo wempilo uzoqala kabusha.

2. I-Fecundity
Ku-shrimp, i-fecundity ibhekisela enanini lamaqanda alungiselelwa ukuzala okulandelayo ngowesifazane.
Ngokocwaningo, izici zokuzala zikaNeocaridina davidi wesifazane zihambisana kahle nosayizi womzimba wabo, inani lamaqanda, kanye nenani lezingane.
Abesifazane abakhulu bane-fecundity ephakeme kunamancane.Ngaphezu kwalokho, abesifazane abakhulu banokufana okuphezulu kakhulu kosayizi wamaqanda, kanye nesikhathi sokuvuthwa esisheshayo.Ngakho-ke, inikeza inzuzo enkulu yokufaneleka ehlobene ezinganeni zabo.
Imiphumela yokuhlolwa
Abesifazane abakhulu (2.3 cm) Abesifazane abamaphakathi (2 cm) Abesifazane abancane (1.7 cm)
53.16 ± 4.26 amaqanda 42.66 ± 8.23 amaqanda 22.00 ± 4.04 amaqanda
Lokhu kubonisa ukuthi i-fecundity ilingana ngokuqondile nosayizi womzimba we-shrimp.Kunezizathu ezi-2 zokuthi kungani kusebenza ngale ndlela:
1.Ikhawulela ukutholakala kwendawo yokuthwala amaqanda.Ubukhulu bensikazi yezimfanzi bungakwazi ukumumatha amaqanda amaningi.
2.Izinsikazi ezincane zisebenzisa amandla amaningi ekukhuleni, kanti izinsikazi ezinkulu zisebenzisa amandla ekuzalaneni.
Amaqiniso athakazelisayo:
1.Isikhathi sokuvuthwa sivame ukuba sifushane kancane kwabesifazane abakhulu.Isibonelo, esikhundleni sezinsuku ezingama-30, kungaba izinsuku ezingama-29.
2.Ama-diameter eqanda ahlala efana kungakhathaliseki ukuthi usayizi wesifazane.
3. Izinga lokushisa
Ku-shrimp, ukukhula nokuvuthwa kuxhumene kakhulu nezinga lokushisa.Ngokwezifundo eziningi, izinga lokushisa liyathinta:
● ubulili bemfanzi encane,
● isisindo somzimba, ukukhula, nesikhathi sokufukamela kwamaqanda ezimfanzi.
Kuyathakazelisa impela ukuthi izinga lokushisa nalo lidlala indima ebalulekile ekwakhekeni kwama-gametes ubulili bezimfanzi.Kusho ukuthi isilinganiso sobulili siyashintsha kuye ngezinga lokushisa.
Amazinga okushisa aphansi akhiqiza abesifazane abaningi.Njengoba izinga lokushisa likhuphuka, inani labesilisa liyakhula ngokufanayo.Ngokwesibonelo:
● 20ºC (68ºF) - cishe u-80% wabesifazane kanye no-20 % abesilisa,
● 23ºC (73ºF) - 50/50,
● 26ºC (79ºF) – 20% kuphela abesifazane kanye 80% abesilisa,
Njengoba sibona amazinga okushisa aphezulu akhiqiza izilinganiso zobulili ezichemile besilisa.
Izinga lokushisa libuye libe nomthelela omkhulu ekutheni mangaki amaqanda izimfanzi zesifazane ezingawathwala kanye nesikhathi sokuchanyuselwa.Ngokuvamile, abesifazane bakhiqiza amaqanda amaningi emazingeni okushisa aphezulu.Ku-26°C (79ºF) abacwaningi babhalise ubuningi bamaqanda angama-55.
Isikhathi se-incubation sincike ekushiseni.Izinga lokushisa eliphezulu liyayisheshisa kuyilapho izinga lokushisa eliphansi lilehlisa kakhulu.
Isibonelo, ubude besikhathi obujwayelekile besikhathi sokufukamela bukhuphuke ngokuncipha kwezinga lokushisa lamanzi ethangini:
