Chinese scientists replicate eel’s 6,000km breeding journey inside research pool

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.
