Chinese researchers successfully recreated the complex life journey of a migratory eel within an artificial pool. This groundbreaking work, spanning from hatching to spawning, may offer a vital path to prevent the species' decline.

Researchers in China have replicated the epic journey of one of the world’s most fascinating migratory fish within the confines of an artificial pool, potentially saving it from extinction. From hatching to maturity and spawning, eels undergo six stages of physical transformation over at least five years as they travel 6,000km (3,700 miles) from the ocean depths to freshwater rivers and lakes. Zhao Feng and his team from the Chinese Academy of Fishery Sciences used satellite-tracking technology....
