Uburyo Penaeus vannamei yakira ibintu bihinduka mu bidukikije byitwa "stress response", kandi impinduka z'imiterere itandukanye y'umubiri n'imiti mu mazi ni ibintu bitera stress. Iyo shrimp zitabiriye impinduka z'ibintu bidukikije, ubushobozi bwazo bwo kwirinda stress buragabanuka kandi imbaraga nyinshi z'umubiri zizakoreshwa; Niba urwego rw'impinduka z'ibintu bitera stress rutari runini kandi igihe kitari kirekire, shrimp ishobora guhangana nabyo kandi ntizangiza cyane; Ahubwo, niba igihe cy'stress ari kirekire cyane, impinduka ni nini, birenze ubushobozi bwa shrimp bwo guhangana nabyo, shrimp izarwara cyangwa ikanapfa.

Ⅰ. Ibimenyetso by'ingaruka z'imihangayiko y'isambaza byari ibi bikurikira

1. Ubwanwa butukura, umufana w'umurizo utukura n'umubiri utukura w'isambaza (bizwi cyane nka stress red body);

2. Kura cyane ibikoresho, ndetse ntukarye ibikoresho, koga kuri pisine

3. Biroroshye cyane gusimbuka mu kidendezi

4. Udupira tw'umuhondo, utupira tw'umukara n'ubwanwa bwavunitse biroroshye kugaragara.

Ⅱ、 Impamvu zitera stress y'isambaza zari izi zikurikira:

1. Impinduka mu gice cy'ibimera: nko gupfa mu buryo butunguranye kw'ibimera, ibara ry'amazi meza cyangwa kwiyongera kw'ibimera, n'ibara ry'amazi menshi cyane;

2. Imihindagurikire y'ikirere, nk'ingaruka zikomeye z'ikirere nk'umwuka ukonje, inkubi y'umuyaga, imvura idashira, imvura igwa, amanywa y'ihangu, itandukaniro rikomeye ry'ubushyuhe hagati y'ubukonje n'ubushyuhe: imvura igwa ikanashira bizatuma amazi y'imvura ateranira ku buso bw'ikidendezi cy'udusimba. Nyuma y'imvura, ubushyuhe bw'amazi yo hejuru buba buke kandi ubushyuhe bw'amazi yo hasi buba bwinshi, ibyo bigatuma amazi ahindagurika, kandi umubare munini w'udusimba tw'ubushyuhe bw'amazi (photosynthesis algae) urapfa (amazi ahinduka) bitewe no kubura udusimba tw'ubushyuhe bw'amazi. Muri iki gihe, amazi agira ikibazo cyo kubura umwuka uhagije mu mubiri; Ingano nto y'ibinyabuzima mu mubiri w'amazi iracika, kandi udukoko twangiza dukwirakwira mu bwinshi (amazi aba umweru kandi akaba umukungugu), ibyo bigatuma byoroshye ibintu by'ibinyabuzima biri munsi y'ikidendezi kubora no gukora hydrogen sulfide na nitrite mu gihe nta mwuka mubi kandi bigatera kwirundanya, ibyo bikaba byatera uburozi n'urupfu rw'udusimba.

3. Impinduka mu bipimo by’umubiri n’ibinyabutabire mu mazi: impinduka mu bushyuhe bw’amazi, ubuziranenge, agaciro ka pH, azote ya amoniya, nitrite, sulfide ya hydrogen n’ibindi bipimo nabyo bizatuma isambaza zitanga igisubizo ku muvuduko.

4. Gusimbuza igihe cy'izuba: bitewe n'impinduka mu miterere y'izuba, ikirere kidahinduka, itandukaniro rikomeye ry'ubushyuhe n'icyerekezo cy'umuyaga kitazwi, impinduka zimara igihe kirekire, bigatuma ibintu bifatika n'ibinyabutabire byo mu mazi y'isambaza bihinduka cyane, bigatuma imbaraga nyinshi z'isambaza zitera icyorezo cya virusi n'amazi menshi yo mu bidendezi.

5. Gukoresha imiti yica udukoko, imiti yo mu byatsi nka sulfate y'umuringa, sulfate ya zinc, cyangwa imiti yica udukoko irimo chlorine bishobora gutera ikibazo gikomeye ku bisimba.

Ⅲ、 Gukumira no kuvura ingaruka z'imihangayiko

1. Ubwiza bw'amazi n'ibitaka bigomba kunozwa kenshi kugira ngo hirindwe ko amazi anyura mu mazi;

Kongeramo isoko ya karuboni bishobora kongera ubwiza bw'amazi no gukumira ko algae igwa.

2. Mu gihe habaye umuyaga mwinshi, imvura nyinshi, inkuba, imvura nyinshi, umuyaga uturuka mu majyaruguru n'ibindi bihe bibi, intungamubiri zigomba kongerwa ku mazi ku gihe kugira ngo hirindwe ko habaho stress;

3. Ingano y'amazi agomba kuba menshi cyane, muri rusange ingano ya 250px ni yo ikwiye. Ibikoresho bigabanya stress bishobora gukoreshwa mu kugabanya stress;

4. Witondere cyane imihindagurikire y'ikirere kenshi, kandi ukoreshe ibikoresho bigabanya stress kugira ngo uhindure ubwiza bw'amazi ku gihe.

5. Nyuma yo gutemagura cyane, isambaza zigomba kongerwamo kalisiyumu ku gihe kugira ngo zikomere vuba kandi zigabanye ingaruka mbi.
