Annotatsiya: Ushbu maqolada suv resurslari cheklangan sharoitda kichik hajmli sun’iy havzalarda Bioflok texnologiyasini (Biofloc Technology – BFT) qo‘llash orqali baliqlarning tirik vazni o‘sishi, ozuqa konversiyasi koeffitsiyenti (FCR) va umumiy mahsuldorlik ko‘rsatkichlarini oshirish masalalari yoritilgan. Tadqiqot davomida uglerod va azot (C:N) nisbatini 15:1 darajasida saqlash orqali hosil qilingan mikrob massasining baliq oziqlanishi hamda suv sifatini barqarorlashtirishdagi roli tahlil qilindi. Natijalar shuni ko‘rsatdiki, BFT tizimida parvarishlangan baliqlarning tirik vazni an’anaviy oqova usulga nisbatan 22,4% ga yuqori bo‘lib, ozuqa sarfi 23,8% ga qisqardi va suvdan foydalanish samaradorligi 90% dan ortiq tejaldi.
