A recent study by researchers at the University of Glasgow has discovered that fish around the world are relocating to colder waters due to global warming. As the Earth’s sea temperatures rise, fish are moving closer to the north and south poles or to deeper waters to keep cool.
The rising temperatures affect various aspects of fish life, such as their ability to reproduce, grow, and digest food. Many fish have specific temperature ranges they can survive in, so even a slight increase in temperature can make their habitats uninhabitable.
While some fish can adapt their bodies to the changing temperatures, most are unable to do so and have no choice but to move to different areas. This migration has led to declining fish populations globally, and in some cases, certain fish species have disappeared entirely.
The study examined 115 different fish species across all seven oceans, making it the first study of its kind on such a global scale. Researchers found that changes in marine life due to global warming have occurred up to seven times faster than changes in land animals.
