Chinese Scientists Successfully Breed Eels In Captivity

WBUR Boston Beijing 13d11d Impact 5

Chinese scientists have managed to breed eels in captivity for the first time. This meticulous process allowed for the successful cultivation of the species. The study focused on environmental factors and feeding patterns in natural habitats. Researchers successfully cultivated more than 3,000 breeding pairs, resulting in 3 million baby eels. The study was conducted to address the demand for eels, which are considered a delicacy. The eel population has declined by approximately 90% over the last 30 to 40 years due to overfishing and other factors. The species is currently considered endangered by the IUCN. Japan remains the largest consumer of eels, accounting for roughly 70% of the global catch. Professor Lee Baumgartner noted that eel trafficking is a global industry. In 2020, more eels were trafficked to Asia than drugs or guns.

The breeding process involved meticulous signals to trigger reproduction, such as simulating salmon swimming upstream or wildebeest migrations.
