Because the Mediterranean is warming, marine species migrate tens of meters deep into cold waters to ensure their survival, MTI was cited in a meta-analysis of 236 species by researchers at Tel Aviv University.
While the entire planet has warmed in recent decades, this process is especially noticeable in the Mediterranean. In thirty years, the average water temperature has risen by one degree Celsius, and this increase is accelerating. The Mediterranean water temperature range is very cold in the northwest and very warm in the southeast. For this reason, the area is an ideal land for studying how species are adapting to global warming, he said. Jonathan Pilmaker Professor in the university statement.
“Our research clearly showed that species respond to climate change by altering their depth distribution,” said Shahar Chaikin, one of the study’s authors. In the future, decision makers should be prepared for this, for example, this should be kept in mind for marine reserves.
When fishing, be prepared for the fact that the same fish can be caught at greater depths, which means having to sail far to the sea, which requires burning more fuel. “Migration” in this case means rapid adaptation, but there is a limit, which is the sea floor. We are already seeing this in the case of deep-sea fish, such as cod, whose numbers are declining, possibly because they can no longer go deeper,” Professor Belmaker added.
