The People's Republic of China has instituted a programme of scientific breeding of fish in order to meet the needs of the people in Hunan Province. In the past, Hunan has had to have fish brought in from other provinces. In an effort to meet increased demands for more fish, the West Lake Production brigade in the province has built a fish reproduction centre in which fish fry hatch artificially. Members of the brigade have succeeded in making the female spawn early in a controlled pond by giving it an injection of hormone. Several years practice have improved that the artificially hatched fry are pure in stock and low in cost with a survival rate exceeding 95 per cent. Fresh water fishery has developed rapidly because of the work of the brigade and reportedly there is a much better yield of fish.
This programme of scientific fish breeding has also been instituted in other provinces and the Chinese report a 37 per cent rise in output for the first half of 1971. Close to four million fish were successfully hatched artificially in May of this year, two months earlier than usual.

SYNOPSIS: This is a fish breeding station in Hunan Province in the People's Republic of China. It is operated by the member of the West Lake Production Brigade.
The members of the Brigade are working on the scientific method of artificially increasing the yield of fish in the province. In the past, Hunan Province was compelled to bring in fish from other Chinese Provinces. But this practice proved unsuccessful in meeting the needs ??? Hunan's population. In an effort to increase the yield in Hunan's own fisheries, the members of the brigade built the breeding station.
The goal of the programme is to artificially speed up ??? the natural process of egg production. In order to accomplish this, different species of fish are bred in different depths of water. Then, brigade members inject the female spawn with a hormone which induces the early production of fish eggs. The eggs are then filtered out of the controlled environment and out into natural water sources such as lakes or ponds. After a period of time, the eggs grow and the brigade hauls out of the water the benefits of their work, the mature fish.
The scientific method has proved successful. The artificially hatched fish are pure in stock and low in cost with a survival rate exceeding 95 per cent. Fresh water fishery in Hunan has developed rapidly and there is reported to be a much better yield of fish. Scientific fish breeding has been instituted in other provinces in China who also report a rise in output of fish production.
