Explanation:
Although the basic fish-culture technology of China is largely based on traditional practices, a number of new innovations and improvements have been adopted. A major breakthrough in modern times is the artificial propagation of the major cultivated species of carp by the administration of hormones in 1958. Although this technique was also independently developed in India at about the same time, it is only in China that it has been possible to bring it down to the farm level on a country-wide basis and make it a common farm practice. Traditional Chinese fish culture was based on larvae and fry collected from the rivers. Hydro-electric and flood control projects implemented after liberation resulted in a drastic reduction in the availability of fry in rivers and hatchery production became a necessity. This, and effective extension work through the "three-in-one" (farmer-technician-party cadre) combination appears to have helped in the farm-level application of artificial propagation.
