Annotatsiya. Mazkur tadqiqotda Buxoro viloyatining tabiiy hamda antropogen gidrostrukturalarida (Quyimozor, Sho‘rko‘l, Dengizko‘l, Oyoqog‘itma, Zamonbobo ko‘llari va kollektor-zovur tizimlari) tarqalgan gidrobiontlar jamoalarining taksonomik strukturasi, xususan, qisqichbaqasimonlar (Crustacea: Decapoda / Palaemonidae, Atyidae) vakillari bo‘lgan Krevetkalarning ekologik-fiziologik moslashuvi va bioindikatorlik imkoniyatlari tahlil qilindi. Tadqiqot davomida fitoplankton, zooplankton, zoobentos va ixtiofauna bilan bir qatorda, bentik va pelagik Krevetkalarning suv havzalari minerallashuvi, harorat dinamikasi hamda antropogen yuklamaga munosabati o‘rganildi. Qiyosiy-ekologik tahlillar Buxoro viloyatining yuqori minerallashgan zovur suvlarida va gipogalin ko‘llarida galotolerant Krevetka turlarining (Palaemon elegance, Palaemonetes spp.) ustunlik qilishini va ularning makrozoobentos trofik strukturasida muhim reduktor hamda ikkilamchi konsument vazifasini bajarishini ko‘rsatdi. Krevetkalarning suv muhitidagi og‘ir metallar va sho‘rlanish darajasiga yuqori sezgirligi sababli, ulardan ekologik monitoringda bioindikator va bioakkumulyator sifatida foydalanishning ilmiy-amaliy istiqbollari asoslab berildi.
