On July 26, in Shenyang, Liaoning, heavy rains led to an extraordinary sight as large numbers of fish leapt out of the water, creating a breathtaking scene.

Mr. Wang, who captured the event, said there were so many fish it was impossible to count them, suggesting the phenomenon was due to oxygen depletion in the water. This spectacular display lasted for over half an hour, marking his first encounter with such an event.

Meteorological experts explained that the heavy rains caused a rapid rise in water levels in rivers and lakes, disrupting the natural habitat of the fish. The increased water levels likely destroyed the fish's usual living areas, forcing them to seek new environments. Additionally, the rainwater washed in large amounts of sediment and debris, making the water murky and limiting sunlight penetration. This murkiness impedes photosynthesis in aquatic plants, reducing oxygen levels in the water. Facing a severe oxygen shortage, the fish resorted to jumping out of the water to breathe air directly.

This collective behaviour, known as "Berber leaping," is not an isolated occurrence but a survival strategy employed by fish in response to specific environmental changes. It allows them to cope with the crisis and increase their chances of survival.

7月26日，辽宁沈阳。连日暴雨后，鱼群纷纷跃出水面，场面十分壮观。
拍摄者王先生称，鱼多得数不过来，推测是因为水质缺氧造成的，这样的场面持续了半个多小时，自己也是第一次见。
据气象专家介绍，暴雨使得河流、湖泊等水体的水位迅速上涨，改变了鱼类的生存环境。水位的上升可能导致鱼类原本的栖息地受到破坏，迫使它们寻找新的生存空间。雨水冲刷地面，带入大量泥沙和杂质，使得水体变得浑浊。浑浊的水体阻碍了阳光照射，影响了水生植物的光合作用，进而减少了水体中的氧气供应。由于水体浑浊和溶解氧含量下降，鱼类面临严重的缺氧危机。为了获取更多的氧气，鱼群会选择跃出水面，直接呼吸空气中的氧气。鱼群跃出水面并非个别现象，而是一种集体行为。在面临共同威胁时，鱼类会通过这种行为来共同应对危机，提高生存几率。这种现象被大家形象地称为“Berber跃”，它并非偶然发生，而是鱼类应对特定环境变化的一种生存策略。
