Igisubizo cya Penaeus vannamei kubintu byahinduwe by ibidukikije byitwa "igisubizo cyo guhangayika", kandi ihinduka ryibipimo bitandukanye byumubiri nubumara mumazi nibintu byose bitera impungenge.Iyo shrimps isubiza impinduka zibidukikije, ubushobozi bwumubiri wabo buzagabanuka kandi imbaraga nyinshi zumubiri zizakoreshwa;Niba impinduka ziterwa nimpungenge zitari nini kandi igihe ntikiri kirekire, urusenda rushobora guhangana na rwo kandi ntiruzatera ingaruka zikomeye;Ibinyuranye na byo, niba igihe cyo guhangayika ari kirekire, impinduka nini, irenze guhuza imiterere ya shrimp, urusenda ruzarwara cyangwa rupfa.

Ⅰ.Ibimenyetso bya shrimp stress reaction byari nkibi bikurikira

1. Ubwanwa butukura, umuyaga utukura n'umubiri utukura wa shrimp (bakunze kwita umubiri utukura uhangayitse);

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

3. Biroroshye cyane gusimbukira mu cyuzi

4. Ibara ry'umuhondo, ibara ry'umukara hamwe na whiskers yamenetse biroroshye kugaragara.

Ⅱ 、 Impamvu zitera igisubizo cya prawn nizo zikurikira:

1. Guhindura icyiciro cya algae: nkurupfu rutunguranye rwa algae, ibara ryamazi meza cyangwa gukura kwa algae, hamwe nibara ryinshi ryamazi;

2Nyuma yimvura, ubushyuhe bwamazi yo hejuru buragabanuka kandi ubushyuhe bwo mumazi bwo hasi buri hejuru, butera guhuza amazi, kandi umubare munini wamafoto ya fotosintezeza apfa (impinduka zamazi) kubera kubura algae ya fotosintezeza.Muri ubu buryo, amazi agira hypoxia ikabije;Uburinganire bw’ibidukikije bw’umubiri w’amazi buracika, kandi mikorobe yangiza ikwirakwira ku bwinshi (amazi ahinduka umweru n’umuvurungano), ibyo bikaba byoroshye gutuma ibintu kama kiri munsi yicyuzi byangirika kandi bikabyara hydrogen sulfide na nitrite muri leta ya anaerobic na form kwirundanya, bizatera uburozi nurupfu rwa shrimp.

3. Guhindura ibipimo ngenderwaho byumubiri nubumara mumubiri wamazi: ihinduka ryubushyuhe bwamazi, gukorera mu mucyo, agaciro ka pH, azote ya ammonia, nitrite, hydrogen sulfide nibindi bipimo nabyo bizatera intangangore gutanga ibisubizo byikibazo.

4 imihangayiko ikomeye ya prawn kugirango itere virusi hamwe n’amazi manini manini.

5. Gukoresha imiti yica udukoko twangiza, imiti ya algal nka sulfate y'umuringa, sulfate ya zinc, cyangwa chlorine irimo imiti yica udukoko irashobora gutera impungenge zikomeye kuri prawn.

Ⅲ Gukumira no kuvura ibibazo biterwa no guhangayika

1. Ubwiza bw’amazi n’ibimera bigomba kunozwa kenshi kugirango birinde amazi;

Kuzuza isoko ya karubone birashobora kuzamura ubwiza bwamazi no kwirinda ko algae igwa.

2. Mugihe habaye umuyaga mwinshi, imvura y'amahindu, inkuba, umunsi wimvura, umuyaga uva mu majyaruguru nibindi bihe bibi, imirire igomba kongerwa mumubiri wamazi mugihe kugirango hirindwe ko habaho guhangayika;

3. Ingano yinyongera yamazi ntigomba kuba nini cyane, mubisanzwe hafi 250px irakwiriye.Ibicuruzwa birwanya guhangayika birashobora gukoreshwa kugirango ugabanye imyitwarire;

4. Witondere cyane ihindagurika ryikirere kenshi, kandi ukoreshe ibicuruzwa birwanya stress kugirango uhindure ubwiza bwamazi mugihe.

5. Nyuma yo kurasa kwinshi, prawns igomba kongerwamo calcium mugihe kugirango ikorwe vuba kandi igabanye reaction.
