Abstract
Ushbu maqolada Namangan viloyatining turli gidrohavzalari (Norin daryosi, Sirdaryo, Norin tumani Fishville va Sirdaryo atrofi yer osti suvlari) gidrokimyoviy koʻrsatkichlarining qiyosiy tahlili hamda ularning akvakultura baliqlarida stress-reaksiyalarni keltirib chiqaruvchi omil sifatidagi roli tadqiq etilgan. Laboratoriya tahlillari natijasida suv manbalaridagi organik va mineral ifloslanish darajalari (XPK, BPK-5, ammoniy azot, xlorid va sulfatlar) baholandi. Gidrokimyoviy stressorlarning baliqlar gomeostaziga taʼsirini aniqlash maqsadida qonning gematologik hamda biokimyoviy biomarkerlari (kortizol, glyukoza) va Lidokain anesteziyasining himoya effekti (n=14) oʻrganildi. Aniqlanishicha, yer osti va Sirdaryo oʻzani suvlari tarkibidagi biogen (ammoniy azoti >2,1mg/l) hamda mineral birikmalarning yuqori konsentratsiyasi qon zardobida kortizol va glyukoza miqdorini keskin oshiruvchi biramchi stressogen omillar hisoblanadi. Olingan natijalar akvakulturalarda suv muhitini optimallashtirish va stressga chidamli baliq kolleksiyalarini shakllantirishda amaliy ahamiyatga ega.References
