INTRODUCTION 

Biological diversity is one of the important features of 

the Earth's biosphere. In order to prevent and stop 

damage to biodiversity, we need to strengthen our 

knowledge about living organisms, especially algae, 

and their composition. Algae are widespread in nature 

and grow in various ecological conditions of the earth: 

water (rivers, lakes, seas, oceans), soil, barren lands 

and rocks, snow and ice bases, tree barks. Algae easily 

adapt to the environment, that's why they are 

distributed in all geographical regions and regions of 

the Earth. They grow in the deep places of lakes and 

seas where other plants do not grow, in caves, under 

snow and ice, and in hot springs.

The importance of algae in nature and human life is 

endless and diverse. A lot of biomass is produced from 

algae. Since the chemical composition of this biomass 

is different, it plays a big role in the life of people and 

animals. In particular, the life of fish is closely related to 

algae. Plankton algae that grow in water are of great 

importance in the nutrition of aquatic animals. That is 

why plankton organisms are of particular importance 

in the organization of fisheries. 

Also, some algae grow too quickly, causing water 

"blooms" that have a negative effect on aquatic 

animals. 

Algae can have a negative effect on the one hand, and 

a positive effect on the other. For example, 

representatives of euglenophytes, diatoms, and 

golden-colored algae, together with heterotrophic 

organisms, take an active part in cleaning polluted 

rivers, streams, and lakes. 

Algae, a source of food and oxygen in rivers, lakes and 

seas, are habitats for many invertebrates and 

spawning and spawning grounds for fish. 

In addition to providing oxygen to aquatic organisms, 

algae are important in the biological treatment of 

polluted water. Their massive increase in water also 

leads to biological pollution. 

Algae are widely used in various fields of the national 

economy. 

Algae is also a source of vitamins (thiamine, riboflavin, 

folate, nicotine and ascorbic acid), trace elements and 

a number of physiologically active substances. 

Vitamins contained in 100 g of chlorella algae meet a 

person's need for them in 1 night. Due to this, it is 

recommended to have algae in their food for patients 

with cardiovascular and stomach diseases. 

Algae are also known as food and are no less popular 

agricultural products. The percentage of protein in 

their content is high (up to 70%). Algae belonging to 170 

species (81 red, 54 brown, 25 green, 8 blue-green) 

growing in freshwater basins and seas have been 

found to be consumed by humans. Porhyra, Laminaria, 

Gelidium, Macrocystis, Undaria, Rhodymenia, 

Monostroma, Ulva, enteromoroha, Chondris are 

specially bred for these purposes. Among them, 

Porphyia is grown in large quantities in special 

reservoirs. 

From microalgaeMore than 500 tons of chlorella are 

used annually for food purposes in Malaysia and the 

Philippines. 

In Mexico and a number of other countries, the blue-

green algae Spirilina is specially bred to obtain 2000 

tons of biomass per year, and 5-10% of its powder is 

added to bakery products and used for other purposes. 

Algae is widely used as a feed additive in animal 

husbandry. In the 80s of the last century, the profit 

obtained due to the use of algae in animal husbandry 

and cocoon breeding in our republic was 290 mln. 

consisted of soums. 

When chlorella was added to livestock feed, a number 

of positive changes were observed. 

Soil algae are also important in increasing soil fertility 

by accumulating organic matter, improving its physico-

chemical properties and microbiological activity. 

Suvotiar has also been proven to have a positive effect 

on the activity of higher plants. 

Algae growing on the soil increases soil fertility. Algae 

is also used as a bioindicator to determine the 

suitability of lands where industrial waste has been 

removed.

Flacocolloids obtained from marine algae (agar, 

agaroid, agarose, carrageenin, agropectin), alginic acid 

and its salts - alginates, mannitol, sorbitol, etc. are 

important raw materials for various industries. 

Phycocolloids are the most necessary raw materials for 

the food, pharmaceutical, chemical, microbiological, 

textile, paper-cellulose, and perfume industries. Agar 

substance is used in large quantities for scientific 

purposes (bacteriology, applied mycology and 

algology) and sanitary-epidemiology. Alginites are 

used in the production of glue, varnish, paint, plastic, 

artificial fibers, and in food (making ice cream, fruit 

juice, bakery products). 

Most representatives of algae act as biological 

indicators. Depending on the type of algae, the level of 

pollution and purity of water is determined. That is, 

some indicator species live in dirty waters, and some 

live only in clean waters. 

Depending on the distribution of indicator - saprobic 

algae, it is possible to determine the level of pollution 

of the water basin in this area. 

According to the analysis of the literature, the algae 

flora of the water bodies of Central Asia, including 

Uzbekistan, has been studied by many scientific 

researchers. Margilonsoy, Shahimardonsoy, rivers in 

the Central Tianshan Mountains in the Fergana Valley, 

i.e. the tributaries of the Syrdarya, Karadarya, Norin 

Darya, Shahrikhansoy and their tributaries, mountain 

lakes, in the lakes of the foothills of the Amudarya, 

channels in the Fergana Valley, i.e. Big Fergana and 

northern Fergana, Big Chuy, collectors and cisterns in 

Mirzachol , in the Kattakurgan, Bukhtarma reservoirs, 

sholipoyas, biological treatment and fishing ponds, in 

the reservoir of the "Kalgan-Chirchik" fishery, in the 

Chordara reservoir, in the southern reservoirs of the 

Kyrgyz Republic, in the Bozsuv canal and Chirchik river 

basin water networks. 

CONCLUSION 

In conclusion, it can be said that the importance of 

algae in nature and human life is endless and diverse. 

Algae are widely used in various fields of the national 

economy. In particular, the life of fish is closely related 

to algae. Plankton algae that grow in water are of great 

importance in the nutrition of aquatic animals. That is 

why plankton organisms are of particular importance 

in the organization of fisheries. In addition, it plays a 

very important role in the preparation of medicines 

and pharmaceuticals. Therefore, the number of algae 

species should be determined and researched.
