Shark fish and other cartilage fish move to the coast in the Marmara Sea with low oxygen quantities in deep water, Türkiye today I mentioned.
What is happening?
The warmer pollution and water reduced oxygen in the deepest sections of the sea. Hakan Kapasakal, a World Wide Fund for Nature-Türkiye, said that in parts of less than 200 meters in the eastern region, oxygen is now in zero.
This change pushes sharks and similar fish towards shallow beach areas, where they face risks. These fish need at least 4.5 milligrams of oxygen per liter of sea water to survive, but many areas of the Marmera Sea now have less than 2 milligrams per liter.
“Because of the continued removal of oxygen in the deep water, these fish cannot return, but they cannot flourish in their new coastal environments due to overfishing,” Capasakal explained.
Why is this lower marine oxygen in relation to?
When sharks swim to the beach, they create a problem for marine life and people who rely on healthy oceans.
Of the well -known 1,266 cartilage fish, a third of this century can die if nothing changes. These animals are the best fishermen in seafood chains, and when they fade, full food networks can collapse.

The issue is More than just sharks. Low oxygen creates “dead areas” where most marine animals cannot survive. This harms hunting functions and food sources for towns near the Marmara Sea.
In a three -year study, scientists have noted a preliminary rise in shark numbers, but they quickly decreased in 2024. This indicates that the new areas cannot maintain the health of these high fish over time.
For humans, these marine animals lose fewer normal hunters for pests and the lowest mixture of life in the water that coastal cities need for food and functionality.
What is done about this lower marine oxygen?
Work grows to help these threats and increase oxygen in sea water.
WWF-Türkiye has built a wildlife tracking application entitled Gozum Dogada (my eyes on the ground) so that people can report sharks along Türkiye about 9,000 km from the beach.
“The more data we have, the more our efforts are saved,” Kapasakal indicated.
Scientists also fight misconceptions about sharks that instill fear rather than enhance care. He looks at the old shark attack records from the Mediterranean to show that they are very less than people.
If you live by sea, help by reporting the scenes of unusual marine life Local nature groups Or by using the application of wildlife. This gives important information to scientists to follow these changes.
