How was the Rottweiler shrimp species introduced in China? How is the current culture status?

Rotterdammern is widely distributed in the Indian Ocean, the Pacific region of the tropical and subtropical areas. In Pakistan, India, Sri Lanka, Myanmar, Thailand, Malaysia, Indonesia, the Philippines, Cambodia, Vietnam and Australia and other countries in fresh or brackish waters are distributed. When the larvae metamorphosis into juvenile shrimp will gradually upstream anadromous. There is no distribution of the roach shrimp in the natural waters of China.

Chinese official at the United Nations biologist Dr. Lin Shaowen in 1961, in Malaysia, Binlangyu, the first to carry out the artificial propagation of Rottweiler's marsh shrimp, and achieved success. In 1962, he also carried out pond culture experiments, in 1963 achieved success. From the end of a hundred years of Rochester shrimp farming shrimp fry rely on the natural passive situation, so that the Rochester shrimp farming to the artificial direction of the development of new progress, the Rochester shrimp to the Americas across the ocean, Europe and China's promotion is also a major breakthrough.

In the fall of 1976, the Chinese Academy of Agricultural Sciences from Japan, introduced by the Guangdong Fisheries Research Institute, breeding success in 1977, has been divided into 14 provinces and municipalities **** more than 40 units of trial breeding, so far has been the promotion of aquaculture in Guangdong, Guangxi, Fujian, Zhejiang, Shanghai, Shandong, Jiangsu and other places.

Shanghai since 1977 after the introduction of Shanghai, by the Shanghai Aquatic Research Institute trial breeding, seedling and pond in 1979, the success of the trial breeding in 1982, Shanghai East China Sea Farms Aquaculture Company began to culture, after several years of breeding, seedling technology has a new development, the breeding area from 500 acres in 1980 to expand to this year's more than 30,000 acres of nursery farms have also been developed to more than 10, with an annual output of shrimp seedlings more than 400 million tails. The annual output of more than 400 million shrimp seedlings. The country's existing Rochester shrimp farming area of 20 million mu, mainly distributed in the south of the Yangtze River. Now some areas in the north also began to carry out Rochester shrimp nursery farming, with the increase in aquaculture production, Rochester shrimp commodity prices have dropped significantly, the price per kilogram from the past 80 yuan down to 40 yuan or so, to become the masses are happy to accept the aquatic products.
