As early as 15 years before the "clone sheep" was born, that is, in 1982, Chinese scientists successfully cultivated a "clone fish". This is the world's first "cloned fish" successfully created using somatic cell nuclear transfer cloning technology of crucian carp. This crucian carp lived in the world for two years, but later died due to careless breeding.
my country's "fish cloning" technology and the key technology of "sheep cloning" in the UK 15 years later - somatic cell nuclear transfer cloning technology, are almost at the same level in terms of technological breakthroughs and operational difficulty.
