Sea saliva in marmara #Turkey

The nightmare of mucilage known as sea saliva, which has been common in the Marmara Sea in recent years, continues to increase this year. IMM and Bandırma Onyedi Eylül University started working together against sea saliva under the coordination of Istanbul Provincial Directorate of Agriculture.

The thick and sticky substance “mucilage” produced by almost all plants and some organisms, which fishermen call “sea saliva” or “skateboard,” covered the Sea of ​​Marmara.

Istanbul Metropolitan Municipality (IMM), the Ministry of Agriculture and Forestry and Bandırma Onyedi Eylül University, started to work together against the problem of sea saliva, which manifests itself as a white layer on the Marmara Sea and causes fish deaths and bad odor.

In order to find a solution to the sea saliva affecting all the coasts of the Marmara Sea, Bandırma Maritime Faculty faculty members conduct field research under the coordination of Istanbul Provincial Directorate of Agriculture. IMM also provides the necessary assistance by monitoring the process in constant contact with the institutions.


Sea saliva is seen for the first time in the Marmara Sea. The following information was included in the statement made by IMM:

“Sea surface cleaning boats (DYTT) are being struggled against sea saliva that looks like white, light brown and foam. Studies are carried out in deep and wide areas. With the propellers of DYTTs, it is aimed to break down the saliva clusters and collect them. However, due to their fluidity, sticky and liquid-like nature, DYTTs cannot show enough effect against sea saliva. “


Experts say the sea saliva will disappear when the seasonal transition is complete and the sea water reaches a sufficient temperature. Sea saliva is a thick, sticky substance produced by almost all plants and some microorganisms. Sea saliva clinging to fishing nets makes hunting difficult.

Stating that this increase in sea saliva will also affect human health, Istanbul University Faculty of Science Biology Department Hydrobiology Department lecturer Assoc. Dr. Muharrem Balcı said, “Sea saliva is formed as a result of organic compounds secreted by microorganisms in the marine environment by an excessive increase. When these organic compounds come into contact with water, they swell, become visible and sea saliva is formed. Some special conditions are needed for sea saliva to form. “High degrees of nitrogen and phosphate input and water temperature are needed for these special conditions.”

Istanbul University Faculty of Science, Department of Biology, Hydrobiology Department lecturer Assoc. Dr. Muharrem Balcı said, “As the effect of global warming increases with this trend, some special microorganism groups will emerge together with sea saliva. These microorganisms are highly toxic. These toxic substances affect some fish more and some fish less. For example, mussels are less affected by toxic substances. Mussels accumulate these toxic substances and come to our table. You can even paralyze the moment you eat this mussel ”made the assessment.

Sea saliva seen in the Marmara Sea for a while also had its effect in Erdek Bay. While the shores of Avşa Island are covered with sea saliva besides Erdek, the citizens who see the layer surrounding the sea are watching the scenery they encounter with anxiety.
