Oceanologist Mukhametov said that the grouper for which the reward was announced will not take root in the Black Sea
Expert in the field of oceanology from the Faculty of Geography of Moscow State University named after M.V. Lomonosov, Sergei Mukhametov, said that the Mediterranean predator grouper, for whose capture a reward was announced in Crimea, will probably not be able to successfully adapt to the Black Sea due to differences in salinity levels. He noted that cases of such relocation are isolated.
Earlier, the director of the Alushta Aquarium offered a reward for the capture of a dangerous Mediterranean predator, several individuals of which were initially caught off the coast of Crimea in the Black Sea. As reported, this is a grouper that reaches sizes of up to 2 meters and is capable of threatening the food supply of Black Sea fish.
According to Mukhametov, such cases of relocation to the Black Sea are rare due to the significant difference in water salinity between the Mediterranean and Black Seas. The grouper entered the Black Sea from the Mediterranean through the Dardanelles and Bosporus.
The scientist emphasized that although the grouper is a predator, it does not pose a danger to people. However, any new species entering an ecosystem can negatively impact local flora and fauna. He gave examples of other “invaders”, such as rapan and Mnemiopsis, which had a serious impact on the Black Sea in the past.
Mukhametov concluded that grouper, compared to other species, is a more favorable “guest” for the local ecosystem.
