Tropical fish migrate to the extreme because of climate change

Climate change and global warming are becoming more and more negative, which will likely push tropical fish to migrate to polar regions (cold waters) to live, avoiding heat rise. degrees in tropical waters.

According to ScienceAlert, researchers have recently investigated a number of tropical fish species and discovered unexpectedly that they are showing signs of leaving the familiar warm waters to move to the water bodies. cold in the polar. The reason scientists pointed out is climate change.

Each year, a huge number of tropical fish larvae unknowingly move out of Australia's Great Barrier Reef to the South Sea and die from failing to cope with the sudden cold sea temperature. However, under the impact of climate change, many oceans especially in the polar regions are warming up rapidly and opening up to tropical fish larvae to move in and grow easily.

Tropical fish show signs of leaving the familiar warm waters to move to the cold waters of the polar regions.

According to researcher Rebecca Fox from the University of Technology in Sydney, Australia, "Scientists are trying to figure out which species will win and which species will be eliminated when the climate is gradually warming up. , the main purpose is to calculate the effect of warming on biodiversity and ecosystem functions. "

However, researchers are also concerned that, if tropical fish move to cold waters at the two poles, polar life will be seriously overturned . Fox and the team suspect that the migration of tropical fish will inadvertently resemble a territorial "invasion " and push the organisms that live in cold water out of where they live.

If tropical fish move to cold waters at the two poles, polar life will be overturned.

Going deeper, researchers have looked at the body shape of some fish to predict their "invasion" ability in cold water.

Shannen Smith, a member of the research team shared: "When the minimum water temperature rises above the threshold, in which some fish species can survive the winter, they will gradually form a reproductive population. After that, they will compete and share life with temperate and tropical creatures, which can tell us a lot about how fish live and control the community. .

One of the fish species is confirmed to be capable of moving and invading the southern waters of Moorish Idol. This tropical fish has no compatibility with low fruit temperatures. However, Moorish Idol's body shape also revealed that they will not affect the populations of organisms living in cold water.

One of the fish species confirmed to be capable of movement and invasion is Moorish Idol.

That said, the risk of disturbing the biota in the cold water is always present and cannot be underestimated. It is hard to imagine that such turmoil can cause struggles for life, the risk of extinction is very likely to occur and indirectly affect human life.

Fox's team hopes that this study will help scientists better understand what might happen in the future under the current climate change model. The study has also been published in the journal Biology Letters.
