“Attack” mucus in the Thracian Sea


Fishermen The Thracian Sea is afraid that they will remain Without fishsince they are “attacking” phytoplankton – the so -called mucus, a phenomenon that is directly associated with increasing the temperature of the sea.

“We have not seen such a phenomenon since 2021, – says in an interview with the publication “TO” Dimitris Sarikaspresident The Aliyevtical Union of Alexander Popoli. – This mucus is a viscous substance that forms a layer on the networks, as a result of which the “wall” is created, and the fish cannot be caught in this way, as well as with the help of trawl guns. ”

In recent days, the shapeless masses of the so -called sea mucus reappeared in the waters of the North Aegean, in Treki Gulf And on the shores Xantiain the beach area Avdirov. According to Mr. Sarikas, most coastal fishermen stopped throwing networks, the same thing is expected from trawl ships, as this phenomenon is damaged by fishing guns.

“The mucus attacks us again” He says. Mucus, as it is called, is not something new to the region’s fishermen. “She appears every year, but in some years, as in this, she is very intense. We came across her in 2021, and then we did not work at all, ”he recalls. – We know that the main reason is an increase in temperature caused by climatic changes. “.

This phenomenon is also observed in The marble seawhere it is associated with acute cases of pollution and an increase in temperature due to the climatic crisis.

“This affects many people. In our Union, coastal fishermen, together with medium -sized fishermen, make up about 200 families. We learned that this phenomenon even reaches LemnosaAnd Samofrakia Also crowded. But it was found west of us, that is, in Porto-Halace and in Caval. The last time we encountered this phenomenon, it lasted a long time, from mid -February to June, and the situation was dramatic. We are looking for places where you can go, where this phenomenon is not so strong to earn a living. ”

As explains in an interview with the newspaper TO doctor Sotiris Orfanidisdirector Greek agrarian organization (ελγο) “Dimitra”, “This phenomenon is associated with the formation of suspended organic units (viscous macro (macro), which in recent years, especially in the spring of 2021, have created significant problems for the fishermen of the North Aegean, especially in the Gulf of Trucky. They stick to fishing guns, making it difficult to use them. ”

The professor explains that the reasons for the formation of mucus, which is still an unpredictable and irregular phenomenon, are not fully understood. However, he emphasizes: “In our region, it is necessary to investigate the interaction of biological parameters, such as an increase in phytoplankton and the release of exopolimators, with special hydrographic conditions of the region, such as the presence of rivers Evros And Nestos, and currents Black Seathat constantly enrich the Tycian bay with nutrient salts. ”

Although this phenomenon is not new, since it is observed in Mediterranean Sea Since 1729, Mr. Orphanidis explains that climatic changes made him more intense and frequent. “Over the past 50 years in the area Adriaticas well as in other parts of the Mediterranean Sea, large and intensive episodes were recorded, during which viscous macro -sgns covered large sea areas, with serious consequences for fishing and tourism. This phenomenon is also observed in The marble seawhere it is associated with acute cases of pollution and an increase in temperature due to the climatic crisis. Mucus volumes pass through Dardanella and in the Treki Gulf, as was recorded with the help of satellite images in June 2021 “, He explains.

“The main problem is that the increase in temperature leads to heating surface water, which leads to a decrease in mixing and increasing stratification, limits the exchange of nutrients between layers, creating food lack and stress for phytoplankton. From these exopolimators an extracellular matrix is ​​formed, which contributes to the accumulation of particles, forming a jelly -like viscous substance to which bacteria that secrete exopolisaccharides, inorganic particles, fragments, and peeled pollen and mushrooms, creating a certain mucus. There is no way to stop this phenomenon, and today it has acquired the frequency, as we see. ”

“Unfortunately, there is no way to solve this problem so that we can continue our work, and nothing can be done in advance,” says in an interview to the newspaper TO Dimitris Sarikas. – We repeatedly submitted applications for compensation, sent documents from institutes and scientific reports confirming everything that we tolerate, but still have not received any answer. I want to emphasize that in 2021, when the situation was also very serious, and we notified, they told us that this would be considered, but nothing happened. If we do not get help, this year there will be no fish in the summer, and not one summer in the future. ”
