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.
