Farm-drinking water used for the purpose of Quyimozor water reservoir, a water reservoir used for household purposes and cultural To'dako'l, Amu-Bukhara channel car pioner lake's main properties of the studied areas fitoplanktonning qualitative and quantitative study. Fitoplanktonkton had undergone determined that the type of the studied objects. Water samples from the lake and the water reservoir in Chlorophyta bacillariophyta and cyanophyta biomass, whilethehighest total ofthehighest fitoplanktonmany fitoplankton identified. Keywords: ecology, gidrobiologiya, open water bodies, biodiversity, channel, lake, and the totalnumber offitoplankton. Аннотация: Изучение основных качественных и количественных характеристик фитопланктона на изученных участках Куймозорского водохранилища хозяйственно- питьевого назначения, Тодакольского водохранилища культурно-бытового назначения, Аму-Бухарского машинного канала и Пионерного озера. Определение встречаемости видов фитопланктона изучаемых объектов. Cyanophyta имеет самую высокую общую численность фитопланктона в пробах воды озер и водохранилищ, а Bacillariophyta и Chlorophytaимеют самую высокую биомассу фитопланктона. Ключевые слова: экология,гидробиология,открытые водоемы,биоразнообразие, русло, озеро,общая численностьфитопланктонаи фитопланктона. Аnnotatsiya: Xoʼjalik-ichimlik suvi maqsadida foydalaniladigan Quyimozor suv ombori, madaniy-maishiy maqsadlarida foydalaniladigan Toʼdakoʼl suv ombori, Аmu-Buxoro mashina kanali hamda pionerlar koʼlining oʼrganilgan joylarida fitoplanktonning asosiy sifat va miqdoriy xususiyatlarini oʼrganish. Oʼrganilgan obyektlarning fitoplanktonkton turlarining uchraganligini aniqlash. Koʼl va suv omboridan olingan suv namunalarida eng yuqori umumiy fitoplankton koʼpligi Cyanophyta eng yuqori fitoplankton biomassasi esa Bacillariophyta va Chlorophytaaniqlangan. Kalit soʼzlar: ekologiya, gidrobiologiya, ochiq suv havzalari, bioxilma-xillik, kanal, koʼl, fitoplanktonningumumiysoni va fitoplankton. Introduction. As it is known of the ecological system of the colorful – consists of this wealth of biodiversity and enhancing the ecological system. Preserving and enhancing biodiversity is to preserve this nature. Using nature caused by the escalation of the fauna of uzbekistan in the last years, many animal species in uzbekistan remains reduced under strong anthropogenic impact. Of view of the science than with nazir, biomonitoringda fitoplanktonni because play an important role in the study of the development of the solar energy water assures the grass, it's in the form of organic compounds during photosynthesis balls at the same time himself and the other residents of algae produces oxygen, which is necessary for the water reservoir to breathe. Fitoplanktongeterotrof organic substances which are synthesized by organisms - bacteria, will http://www.internationaljournal.co.in/index.php/jasass 44 Volume15Issue03, March2025 Impact factor: 2019: 4.679 2020: 5.015 2021: 5.436, 2022: 5.242, 2023: 6.995, 2024 7.75 serve as a source of energy for animals. Therefore, the features of the ecosystem determines its stateoftied fitoplankton. Some open water ponds and lakes in fitoplanktonning number, biomass, composition and physiological taksonomik will bethebasis to conclude onthestatus ofitsactivity. The research of goal. Open water basinsof water samples from different points fitoplanktonning main qualitative and quantitative study and evaluation studying the properties consistof. Material and methods. When research Amu-Bukhara car channel, Quyimozor water reservoir, a water reservoir To'dako'l the city of bukhara and the lake pioner's fitoplanktonlarini the purpose of a liter samples were taken with a ruttner batometri fitoplankton study: samples were mixed and poured into 250 ml 500 ml containers integrated samples were taken. Plankton nets used for gas collection fitoplanktonni prepared from quality silk, dated 76. Lug solution is a slight yellow color, then 40% of the sample, i.e. formalin 40 ml to 10 liters of 0.5% formalin, adding samples fitoplankton "soft" to make fiksasiya were determined. It should be taken into account that this high-pigment color fiksatorning kontsentrasiyasi grass will lead to changes in thedisplacement of water tothem. Methods the survey was collected on the total samples received in the process of algologik fitoplankton.Fitoplanktonlarning usetodeterminethe determinant of acontent type led. The results of studies: The results of studies carried out shows the Amu-Bukhara car, channel, water reservoir To'dako'l, the city of bukhara pioner lake and reservoir Quyimozor's drinking, compilation of recreational, cultural and irrigation purposes, water used for facilities studied. The research was conducted in the spring and summer seasons of the year 2020-2021. This water sample taken from different areas of the reservoir and the lake of 27 units have been checked. As shown above the channel in the water reservoir and lake water
