Rare Chinese bahaba detected in Hong Kong waters using new DNA tracking

By PulseAugur Editorial · [1 sources] ·

Researchers have successfully used environmental DNA (eDNA) technology to detect the critically endangered Chinese bahaba, also known as the "Tai O fish," in Hong Kong waters for the first time in over a decade. This breakthrough was achieved by Jack Ip Chi-ho of Lingnan University and Wang Junjie of South China Normal University, who developed a highly sensitive genetic identification method. The detection of the fish's DNA in September of last year suggests that some of the approximately 1,300 hatchery-reared juveniles released into the Pearl River Estuary in August may have migrated into Hong Kong's western waters.
