Due to the large catch of anchovies in the Sea of ​​Azov, a “jellyfish catastrophe” may occur, including in the Taganrog Bay.

This year, fishermen increased their catch of anchovy in the Azov-Black Sea basin by 30% compared to last year. At the beginning of February, 5 thousand tons of anchovies (anchovies) had already been caught. At the same time, due to the increase in water salinity in the Sea of ​​Azov, the number of jellyfish has also increased. Since the anchovy is a natural enemy of jellyfish, a decrease in its numbers leads to an even greater spread of jellyfish, which negatively affects tourism and fishing. Scientists have proposed two ways to combat this problem: increase the flow of fresh water into the Sea of ​​Azov and increase biological competition for food, stimulating the spread of anchovies, which limit the number of jellyfish. However, for this it is necessary to reduce commercial production of anchovies and try to restore their population in the Sea of ​​​​Azov, otherwise the number of jellyfish will increase every year.
