Ocean oxygen reduces deep marine fish population and marine health, new alerts of the study

An international study headed by the Institute of Environmental Science and Technology, the University of Auto Nonoma de Barcelona (ICTA-UAB), has investigated how the marine ecosystem responded to the past episodes of the Ocean Documentation. To do this, researchers studied the remains of lantern fish – which is one of the most abundant and important fish families in the deep sea – which is preserved in the Eastern Mediterranean sea floor, which is more than 10,000 years old. Their searches have appeared in the journal Communication Earth and Environment.

Lantern Fish is a very small marine fish in the Myctophoid family, named for their ability to produce light through the bioylomanis organs. Regardless of their small size, with an estimated 600 million tonnes, the global lantern fish is in large quantities, possibly making them the most abundant on the ground in terms of weight.

During the day, the lantern fish lives in the Dark Mesopalic Zone (200-1,000 meters deep) to hide from hunters, while at night they float at sea level to feed on zoplankton. Due to both their great biomass and Dell’s vertical migration, the lantern play plays a very important role in the fish climate rules, and the nets of the sea, which connects the surface to the deep sea. Therefore, the lantern fish is widely regarded as a good indicator group for the health of the mesophalogy ecosystem.

However, the focal record shows that the lantern fish was largely absent during the period of extreme oxygen deficiency. They only increased the oxygen level once again 6000 years ago.

Researchers, including bio -diverse research centers. The Eastern Mediterranean Sea, which has changed well in the last 10,000 years between oxygenid and extreme molecules, has provided a unique natural archive to study the biological effects of doccination events.

“The case of lantern fish clearly makes it clear that if the Ocean Docs continues on a large scale. If such a large group of large Bidamas disappears, other maritime species is also at risk,” the main author of the study, Swin Palex, warned.

The twilight zone – the mesophyllic zone, which is located at 200 and 1,000 meters deep, plays a key role in the land climate system, mainly through its influence on the global carbon cycle. The results suggest that the mesophyllic ecosystem is particularly at risk of oxygen damage. Their elimination can destabilize the environmental balance in the sea, damage its role in global carbon cycling, and pose a threat to marine biological diversity and global food protection.
