as they say, he gets to the root of the matter, you can't say it any other way, but the words of our president, spoken at this meeting, you know, they are not just prophetic, they simply put everything in its place, perhaps that's the right way to say it, because forewarned is forearmed. in this situation , we clearly see what can happen to our country, what can happen to our neighbors, in principle, we just talked about serbia, because this is a clear example of the continuation of the permanent involvement or destruction of the country, drawing it into its orbit, according to by and large, absorption, and this is what is in store for most countries in the world today, including the republic of belarus, we remember 2020. if we do not fulfill what

is destined for us, we are destined for the main thing, to preserve our country and take those steps that will allow us to be sovereign, independent, and this is not only a military component, this is not only a law enforcement component, this is primarily the economy and unity, yeah, unity in various spheres, we must unite our efforts if we want to survive, we must unite. efforts to find common ground on the basis of dialogue, dialogue, hear each other. yeah. andrey petrovich, what conclusions do you draw from this difficult time the cis is going through, if earlier it was created with the purpose of, as they say, in a gentlemanly way to separate our countries of the former soviet union, that in principle they separated, as it should be, that is, out of twelve countries, by and large , eight remained, which came to us in minsk. the head of state said very correctly, a hybrid war is underway.

development in all areas from defense to sovereignty, justice, development, and the most important one for the economy. thank you for this conversation, that's all for today, happy.

today we will talk about jellyfish, well , fishermen have one question, what is it, who knows? this is a jellyfish, craspidacca saverbii, a freshwater jellyfish. which is considered an alien species in our country, it is very difficult to grow them in aquariums to the stage of such a good jellyfish, because they are very demanding, if a crayfish survives in fishing nets for several days, then how to deal with it, you need to dry it networks, and in the second edition we have already included species that cause harm to forestry, agriculture, fisheries, what is an invasion, this is when a person helped to move somewhere, this is the same kindness of the soul of the world.

hello, the program "say don't be silent" is on air. in the studio victoria popova and tatyana shchyurbina. and today our guest is a candidate of biological sciences, tatyana lepinskaya. good afternoon, tatyana. not long ago we talked with your colleague elena gaidachenko about invasive fish, today we will talk about jellyfish, because the blagosfera and social networks are literally filled with videos from our rivers, where fishermen. find jellyfish, let's watch one of these videos, so now i'm like this, western dvina, question, who knows, it looks like jellyfish, i don't want to touch it, that's for sure,

by the way, there are a lot of them, look how many of them are behind, there's a whole school of them, around there. also from an amateur fisherman, this is the craspidocustra saverbii jellyfish, a freshwater jellyfish, which is considered an alien species in our country, last year western dvina, but in fact we already knew that we have them, in in the eighteenth year we had a project with new zealand, and

we discovered in some of our rivers using molecular methods with ordinary dna that it exists, but we did not physically see it, it was may when we took samples, then in august of the same year, the eighteenth, we already received from local residents a video and photographs of this jellyfish from the mushroom channel in brest, that when the jellyfish bloom, as they call it in the literature, when it broke away from the polyp and rose already in the jellyfish stage, people noticed it, it reaches - 2-2 cm in diameter, the bloom of jellyfish sounds so beautiful, like they tore themselves away from a dandelion, but... that's what they call the bloom of minutuses in hydrogeology, but for scientists it was a surprise or you basically had been studying it for a long time and assumed that this was possible? it was not a surprise, because the invasive process is underway, due to the fact that

the average annual temperature is rising, various species from the tropics, subtropics can come to us, this species is still an aquarium species, if... people release something from aquariums, it attaches to plants or other animals get into the environment, or there is evidence that it is carried by birds, when... in the polyp stage, small pieces break off from the polyp, get into the aquatic environment, then in the place of accumulation of waterfowl, the birds swim in the water and then carry it to other places, this is an asian species that originally came to europe, and then spread throughout the globe, except for antarctica, so far, if they are not in antarctica, that is , they can survive there.

using environmental dna, we took water samples, filtered them and by dna we found that yes, it is there.

very passive and - let's say, lie on the bottom and feed on the bottom, but when the temperature is high, they rise and accordingly attract attention to themselves. the most important question, probably, are they dangerous for humans? in most cases, no, but there is data in the literature that when there are a lot of them, when it's just mm, a mass bloom, let's say, of water, there are a lot of jellyfish. then there were cases when someone complained of redness, itching, well, as if we

definitely don't have scientifically proven facts there, because they are not yet quantity, i read comments from various people who encountered jellyfish, they said that they took them in their hands, as if nothing happened, no burns, nothing, when you put them in an aquarium with fish, the fish hide from them, because yes, because they can meet, well, as if for...

well, the western dvina, so where else have they been found , here is the mukhavets mushroom channel in brest, we were also sent photographs from near mozyr, but in general, according to dna, we found them in the dnieper, in it they are, they are everywhere, if they are there, then they are everywhere, especially if they are later they carry. with birds, then where there is a large number of accumulations of waterfowl, there , well, obviously not, but in general, in principle, why is this an invasive species, why are they harmful to our environment, to our. what threat do they pose? always new - species, let's say, not our natives, they are undesirable for our fauna, because if you take a jellyfish, they are predators, they eat zooplankton, they are competitors with our native fish species, competitors with fish fry for food, so they damage the ecosystem,

the ecosystem is being rebuilt. is it possible to prevent their reproduction in some way other than complete freezing? well no, there is no possibility of populating some other fish that would eat these jellyfish, there is no such thing, i don’t know about fish , i read that their main predator is crayfish, but that’s also a controversial issue, well if you say they feed on crustaceans, big crayfish eat them - these are small daphnia, cyclops, there are very small ones. every year and broad-clawed, and their numbers are decreasing due to the same invasion of the american

striped crayfish, which is a carrier of the plague, crayfish. how did these american ones appear here, again through poland, and they appeared in the nineties, our scientists discovered, the first in the grodno region, they came through the augustow canal, yes, this is an american species, through poland, spread throughout the grodno region, the neman river, tributaries, then

the belovezhskaya pushcha river, now here is the latest find. which we had, they are already in the dnieper-bukh canal 20 km from pinsk, that is, this is already the dnieper river, like a river basin dnepr, well, let's fantasize with you, tatyana, in this way the ecosystem changes in general, if these striped ones finally take root there and jellyfish eat our native flora, then we will simply come to the fact in the future, yes, that the flora process will completely change. yes, it is like that, it is going on, it depends on both the increase in average annual temperature and human activity, naturally, there will be changes, and we will observe this, but we are doing everything possible, sometimes it seems to me, and it is impossible to prevent this, it is prescribed in legislation, what is allowed, what is not, how

to prevent the introduction of invasive species, distribution is prohibited, the resettlement of invasive species is prohibited. we make many methodological recommendations, we implement this in places where there are a lot of the same striped crayfish or other invasive species, how to deal with them and what to do if they are found, if the crayfish survives in fishing nets for several days, then how to deal with it, you need to dry the nets, and who would you call the main orderly of our reservoirs, here if we take benthic species, the first thing that comes to mind is probably to...

at least return the coastline to the level where people could enter safely, well, the black book of invasive animals has already gone through two editions.

all the videos were like that soon we will be catching crocodile sharks. tatyana, as a scientist, do you agree that our fishermen will soon be photographing sharks in the dvina? i really hope not, but it all depends on us, as citizens, because everything that we keep in an aquarium can be bought now everything via the internet, you understand, but please, keep everything you have tamed at home until the end.

how many obstacles need to be overcome, dams, reservoirs, and in general the mileage, customs - this is completely separate, but here they built a reservoir, wanted to increase fish productivity, took them to the sea, settled them there, they took root, with the help of man , the borders are erased, but i was interested that you have facts about how - these invasions harm our farms, they breed in the fields. well, this aphid control, control of all kinds of grain beetles that damage grain or the same bark beetle, forestry, there are many nematodes

that are found in fish farms and are somehow controlled there, if we take aquatic organisms, for example, there were lakes where there were a lot of long-clawed crayfish and it was possible to carry out fishing, but with the introduction... with the appearance of american crayfish there, the population, one might say, disappeared, and this american one is cooked, at least they eat it, yes, but it is very small, they say, i have not tried it, it is not a very dense predator, from a commercial point of view vision is not interesting for us, yes, but in my opinion, now our entrepreneurs are already considering it as an option, that's why allergic reactions in...

separate other animals, so we just watch the jellyfish, get used to their bloom, right, with jellyfish, yes, let's take a break, for now , not for long, i remind you, we have a telegram channel, say don't be silent, subscribe, ask questions and suggest guests, we have connections, the program "say don't be silent" is on the air again, and today. our guest is a candidate of biological sciences, tatyana lepinskaya. tatyana, we read that in belarus the damage from the invasion has not yet been assessed in monetary terms, but there are countries where they are trying

to calculate this damage. yes, we have not yet had an assessment of economic damage, we have not counted, but in the near future a project is planned to assess the damage from the introduction of the invasive species of american striped crayfish. yeah.

it is written in the convention on biological diversity, all countries that have signed this convention, they must minimize, carry out various measures to prevent the introduction of invasive species into the country, and if they have already appeared, then fight them. well , how to prevent the introduction, if you are talking about the plumage of birds, but birds want to fly everywhere. yes, but these are, let's say, isolated cases, but the majority is. by man, after all, yes, yes, by the way, there is such an intergovernmental scientific and political platform on biodiversity and ecosystem services, it includes 143 states, over the past 4 years, scientists have been compiling a thematic assessment of the threat, what you have already commented on, this is the figure of 423 billion dollars spent on combating invasions in 2019, which is very impressive, on the other

hand... well, we always hear that scientists pump out money for any fight from good to good or good to bad, well , like for these programs, so challenge this opinion that the climate, global warming, these environmental threats, invasions, they really require huge costs, but their effectiveness is zero, or not? well, i do not agree that the effectiveness is zero, because there is a positive example. when an island state was introduced with some invasive species, they carried out a fight, which caused great damage to both nature and ecosystems in general, and after the struggle , their own native aboriginal species returned, each state strives to preserve aboriginal species as a national treasure,

this is important.

there are always meetings, there are working groups, meetings are held, after which reports are compiled, there is always communication between countries, neighbors, what species, there are lists of species, what alien species there are, what invasive species have already moved in, and let's say , we are always up to date with what is happening on that territory we can always prepare for the introduction of some new species. for example, now we are developing a list of species of invertebrates that could potentially come to us in the near future, we are making lists, we are helping each other in other ways, for example, if we discover some species here, we inform our colleagues, as we did with the amphipod, we discovered it here, then we informed our polish colleagues,

they after some time in their... their country to find out what, how many and where, what species are there, this was the eighteenth year, we conducted online trainings at the beginning, when we were taught the theory, then there was practice in canada, barcoding - what is it, it is

a molecular method that allows you to accurately identify a species, by its dna, like in a store we read a barcode, a bar code, yes, that's how it is here with dna.

who are we waiting for, well, tell us, what aliens are we waiting for now, besides jellyfish, list them, yes, from aquatic organisms we are expecting several species of decapod crustaceans, which, oh my god, we haven't figured out the striped ones yet, now decapods, striped - it's the same decapod, this is a marbled crayfish, red swamp crayfish, crayfish attack us, it turns out, there is no need to make such statements.

somehow these here wash before how the planes clean there in general there is a system clean check dry, that is, clean, check, dry, the same is with biofouling ballast water, the ship must go out, drain the ballast water somewhere in the ocean, take on other water, which is oceanic and moor in some port, this is prescribed, there is even a convention on ballast water. the same with cleaning ships, cleaning bottom, and even our small vessels, all holders, owners must monitor and , as it were, clean them so that there are no foulings there, plants have wound up,

various alien species have attached themselves there, this vessel travels from one place to another, they must, as it were, clean them, but probably few people still follow this, so we want to make recommendations and, well, you see, these are only recommendations, until you make it... mandatory, no one will do it, because this is an extra expense, accordingly, profits are reduced, why a person to spend the company, will spend money on cleaning the vessel, if it is possible not to do this, it is simply recommended, yes, it should be introduced under some other responsibility, that is, this is a question for our legislators, perhaps, yes, maybe they should somehow revise, and not only to ours, in general, but also to polish and... advanced in this regard, because when you communicate with colleagues from other countries of the post-soviet space, i will say

this, then we already have lists, there are the terms are prescribed in the legislation, there are state programs, after all , there is a black book, this was also an important step , yes, for a long time. studied in belgium at the university of genoa,

then did an internship in canada, at the ontario institute of biodiversity, well, there was probably an opportunity to stay there or in europe or in the same canada, but you decided to return to belarus, why? when i went to belgium, i had a master's degree in marine biology and biodiversity conservation, i had almost finished my postgraduate studies here when i i left, then i promised, i will return, i will have a defense. i will become a candidate of biological sciences, because everyone said, well, as usual, he will leave, he will not come, no, and i kept my word, returned 7 months after returning, defended, in canada, in canada i had an internship specifically in barcoding, when after the defense i took online courses, it was just an internship to come to the places where we already do, therefore no, that is, they never regretted that they stayed there, no, no,

it gives pleasure that i can do something to do for our country, for our ecosystems, it is always a search, some kind of scientific search, always, as they say, brainstorming discussion, brainstorming, yes, yes, yes, always some projects, new knowledge, i love to study, i am still studying, in belarus we have enough opportunities to get an education in your field, and in general , is science given due attention? in our country, i would like, probably, a little

more, let's say, but for young specialists, i think that it is very good, well, when you were a young specialist, you came to the workplace, what were your conditions, what would you like, or maybe there was something extra, no, there is never something extra, there were good conditions, always some new competitions for young specialists, grants separately up to 35 with a degree without a degree, at our institute this was supported. because well, what is a scientist, yes, it may

dawn on you, it may not dawn on you, it may be a find, it may not, you will agree that it is not difficult, in general, it seems to me, in each, in each job, in each activity there are pros and cons, here you are you say it's a cushy job, when hydrobiologists come and take these soil samples, people come up to us and say: oh, well, what a dirty job you have, poking around in all this and looking for all sorts of species, so no, i like it. close, let's say, always a connection with nature, on the shore of a lake or river, always communicating with people, but this is usually in the warm season, or you have to also take some samples in the winter, let's say, go somewhere on expeditions, if there are projects on a certain species and there there are lakes and ice fishing, then yes of course, but in most cases we work when everything has already opened up, winter has passed. and then it goes, well, actually, understanding the processing

of samples, yes, if necessary, then molecular processing, and simply identification of species, there is experimental work, well, it seems that you , tatyana, know everything about what kind of water there is in belarus and where it is the cleanest, here is where you and your family vacation, you have a husband, a son, yes, yes, you probably go to our reservoirs or not, or do you have enough of them at work, honestly, i don’t i swim in our waters, because...

yeah, and there are species from lithuania, from latvia, but we haven't discovered them yet, the biggest damage, it seems to me, is that the fish are getting smaller, many fishermen talk about this, they used to go to the dnieper to fill their bins there, yes

, there are fish, but now there are fewer and fewer of them, that's actually what this means for us, and the fight, well, as we found out, tatyana, this is also... it scares me, there is none, essentially, for now we are only observing, no, we are not resettling, we are prohibiting resettle, uh, it is prohibited to move not only within the boundaries of some basin, but in general to resettle to other bodies of water, to reduce the population, if it is possible, well , here are the prohibitions, what are they, well, who will forbid a person who is tired of his aquarium to go and turn it out, well, yes, therefore, probably, we should have some... let's say so, so that it hits the pocket, here you evict, get a fine, well , that is, if, well, that is, again we return to the fact that some legislative measures are needed, we are working on this together with the ministry of natural resources, and we will take a short break, after short break we will return to this studio again, for now subscribe to our telegram channel,

say don't be silent, look for all our releases on the belarus 1 youtube channel . the most current events from the world of sports: 25 medals in total were won by the belarusian youth athletics team in the match against the russian team. work and discipline give results. it is on this principle

that such countries as germany, bulgaria, israel appeared. today we are implementing several investment projects in order to increase the competitiveness of products, an approach to business that everyone can strive for. all our products,

which we produce in our workshop, are tasty and healthy. made from 100% natural raw materials. even children can eat them, all food products require the approach of a good, competent, kind housewife, it seems to me that this is so, at least i have always set such tasks for myself that what i like, i roughly understand what our consumers will like, watch the project quality mark on the belarus 24 tv channel. on air again say don't be silent we have a candidate of biological sciences in the studio today.

some mollusks, all that, that's why when, why i said that when hydrobiologists come, especially those benthicists, then all the people around, what a dirty job you have, where does such interest in such dirty work come from, namely in the inhabitants of the bottom, who live, the interest appeared back in university, in the third year, i began to study bioindication, and bioindication is mostly... work with the benthic community, river indication, that's so i came to the academy of sciences from the third year,

that is, it is interesting for you, it is just , that is, this is work for the soul, as they say, yes, therefore, it is a very holiday to work, yes, as a holiday, well, you like to travel, accordingly, you can assess the environmental situation in belarus, in your opinion, are there any serious reasons for concern, no, because everything is quite... favorable, let's say, but this trend is not only here, everywhere in the world, it seems to me that the number has increased garbage, on the banks, around bodies of water, in the forests, here are places, in places of rest, this is just some kind of pain, a cry from the heart, when you come, it seems like we used to go there, rest, but maybe it wasn't as accessible, or people somehow left, that cleanliness is our everything, yes, but now i have a feeling. that there is more garbage, you have a camera, you can appeal to the viewer not to litter, clean up after yourself, clean up after yourself all

your products, well, you know, this is some kind of widespread problem, i've also been in different countries, such beautiful places are amazing, it is even impossible to imagine that nature created them so beautiful, but everything is spoiled by this pile of garbage that is left, again the reason for everything is a person, and what do you think, why did it used to be less, because?

full bags of everything, but take away the empty ones, it is not difficult, or at least, now we know that the whole city is covered with cameras, maybe some of the most, well, frequent places of accumulation of people in nature should also be equipped, well, it seems to me that people do it on their own they won't look after themselves until big brother looks after them, what do you think? yes, of course it's possible to equip them, but it takes so much effort, money and human resources to track them down, find them, find that... person and prosecute them, well, unfortunately, there's no other way, otherwise we'll just get overgrown, i saw that the fines for not wearing

a seat belt are also small, but there are so many cameras , they only fine drivers for speeding, now almost everyone wears a seat belt, you see, it was the only way to eradicate it, you're really right it concerns water most of all, because boats are thrown into the water and in general, well, when there is a strong wind, we see what is washed up on ours. and in the ocean there are even real garbage islands, which, when the current clutters everything up, and there is a lot of garbage there, by the way, this garbage is also like a carrier of invasive species, it attaches somewhere, then the current carries this species to the same place, and scientists can’t remove these islands, well, no, that is, they drift like this, and let them set up some kind of nets or something like that special...

the taste of iron or chlorine, well, for example, in some areas of minsk i can't even drink tea, you feel it, yes, then of course people put filters, but so, artesian, let's say, in minsk, where there is artesian water, it is quite possible to eat it, even without filters, cook food on it and drink it raw from the tap, no consequences for health, well, as for me, everything

is fine. you are learning to play the piano yourself, as far as we know, yes, why did you decide to get interested in music now? oh, good question, i, as far as i can remember, have always been doing something, like with my hands, fine motor skills, knitting, cross-stitching, then there was a moment, you know, painting by numbers, oh, how addictive it is, well, it came to music, once, while putting the child to bed at night, the neighbor started playing.

i don’t have an instrument at home at the moment and i only go to school to practice, but i understand that i need to, i want to, this is what i think is for the soul, especially when at work there is always... there is a lot of stress on the brain and you want to come, relax, well and show your son by example that you can still relax like this. do you also study musical notation or do you just hear it, that is , how these lessons are held, because i know how it happens with children in music school, the whole system is completely clear there, for an adult, that is, how it

all works out for an adult i immediately had a point, please don't... i don't need this with music, oh no, i have a lot of friends from bavalia and i heard about it, i don't want it, and we agreed with the teacher that we would to analyze some soundtracks, to learn these notes on them and read the notes, and like here is a composition and we learn, well, it is clear, tatyana will learn three or four compositions of soundtracks, she will perform effectively somewhere in a company. "you know what my dream is, sometimes - when you go somewhere to a conference, especially now these long layovers, because everything has become very complicated, let's say, with flights, and sometimes in airports there are pianos, it's so nice when you sit for several hours someone comes up and plays some composition, everything at once, right

it seems that life at the airport is changing, that's it. i have an idea to play something like that, to bring joy to people, yes, that is, you see your mission in bringing, as you already said, benefit to the state, yes, to do something for your country, yes, for nature. to please all people with something, yes, well, of course, i was especially impressed that tatyana doesn't swim anywhere, that's amazing for me, here's a hydrobiologist, yes, well, the shoemaker's children have no shoes, classic, well, your son, he's 4 years old, he's accustomed to water, yes, he swims, and it swims in the pool, in rivers, in lakes, in the sea, and you can't pull it out, like all children, well, we wish you to find even more in our waters. shocks still on this matter,

so it's great that you said that belarus is advanced in this regard, we were pleased to hear this from you, well, jellyfish are safe if there are few of them, tatyana shcherbina, victoria popova, we say goodbye to you for today, goodbye, goodbye, now tatyana lipinskaya is speaking, friends and nature lovers. think about those you have tamed, and be with them until end, there is no need to release them into the wild, into our water bodies, let them stay with our native species. tatyana, we ask you to leave a master's signature on our charming picture and some wish as a keepsake. my favorite latin expression is perasperadastera, the cross of stars.

there are 100 brave guys in our studio, each of them has a question for an adult. you have one minute to briefly tell about yourself. time is running out. how will you react if a person asks you to do something that he does not will do. well, i will also dissuade him somehow. there is a stereotype that all athletes study poorly, how did you study?

sleep, i could not fall asleep, because i closed my eyes, i had the whole day in front of my eyes, how it went, how i woke up there, what i ate, watch the project 100 questions to an adult on the belarus 24 tv channel.
