Live: Tides of Change Part II - How do croakers turn from silver to yellow?
CGTN, 11 Sep 2021
The wild yellow croaker was a scarce species in southeast China's Fujian Province. In the daytime, it is silver-white. At night, the golden skin gland under each scale in the lower part of the side of the large yellow croaker can secrete and make the fish golden. Over the past few years, Fujian's Sanduao, a deep water harbor, has put more efforts into increasing the number of yellow croakers by breeding them. CGTN reporters Zhao Yunfei and Yang Xinmeng visit a marine farm that breeds and sells the fish and witness the fish turning from silver to yellow as night falls. #TidesofChange
