Chinese Fish Culture,
Abstract
One-third of China's 45 million acres of rivers, lakes, ponds and reservoirs have the necessary conditions for fish culturing. In addition, there are storage reservoirs, waste disposal ponds, and 7 or 8 million acres of rice fields in which some fish culturing can be conducted. Most of China is situated in temperate and subtropical zones, which affords a suitable water temperature and a long growing season for fishes. For instance, in the Pearl River and Yangtze River, where 60-70% of the freshwater areas in China occurs, fish feed and grow all year long. After 1949, the Chinese government instituted radical reform. Fisherman were given their own fish ponds and culturing tools, many forms of government assistance were made available, and communes were developed to further enhance fish production. As a result, freshwater fish production increased from 50,000 tons in 1949 to 1,000,000 tons in 1959. New techniques have been successful in developing large scale artificial hatching, utilizing naturally occurring fry, culturing of species and improving survival rates of carp and other fish species. In addition, improvements have been made in fish food production, elimination of fish diseases and enemies, and harvesting of adult fish.
