Global warming is causing most marine fish species to seek cooler waters, moving closer to the North and South Poles.. Or they're starting to go deeper, according to the University of Glasgow..

For marine life such as fish, ambient water temperature plays an important role in maintaining many body systems.. In particular, it affects metabolism, growth and the reproductive system.. Moreover, the range of temperatures suitable for the survival of marine fish is often very narrow, due to which they cannot adapt to even small changes in temperature..

During the study, scientists studied data on 115 species that live in all major regions of the ocean..

“We have observed a striking trend in which species living in areas that are warming faster are also showing the fastest shifts in their geographic distribution.. It is possible that warming rates in some regions may be too high for fish to adapt, so relocation may be their best survival strategy.. At the same time, we see that their ability to do so is also affected by other factors, such as fishing, as commercially exploited species move more slowly,” said study lead author Carolyn Dames..

Earlier, scientists said that part of the United States is slowly sinking into the water. Sea rise rates are higher along the Gulf Coast and southeast, researchers say.
