Red Tide Hits the Black Sea: A Concern for Ecologists and Beachgoers

The Black Sea has undergone a dramatic transformation off the coast of Odessa, turning a tile-red color following a recent rainstorm. According to ecologists, this phenomenon is attributed to the rapid growth of phytoplankton, specifically algae.

As a precautionary measure, a recommendation to refrain from swimming has been issued. Furthermore, multiple dead rats have been discovered on the shore of one of the central beaches, sparking concerns about the potential health implications.

Vladislav Balinsky, head of the public environmental organization “Green List,” explained that the red tide is caused by the rapid growth of unicellular dinoflagellate algae, primarily Lingylodinium polyedra. This has led to the presence of toxins in the seawater, posing a risk of allergies and poisoning when consuming seafood.

Balinsky emphasized the need to investigate the cause of this phenomenon, citing potential factors such as seawater nutrient pollution, desalination, and the long-term effects of Kakhovka’s sabotage on the environment. The ecologist also noted the risk of mass starvation processes and the occurrence of bright bioluminescence.

Local residents have taken to social media to share videos of the numerous dead rats found on the shore of one of the city’s central beaches following the heavy rainfall.
