Artificial Breeding, Nucleus Insertion and Pearl Culture Techniques of (Pinctada maxima, (Jameson)
The achievement was conferred National Science Congress Award in 1978, First Class of Science and Technology Advancement Award by Agriculture, Animal Husbandry and Fishery Ministry in 1985, and First Class of National Science and Technology Advancement Award in 1987.
SCSFRI successfully achieved in the artificial breeding of Pinctada maxima(Jameson) in 1970 for the first time. The international advanced technologies of artificial reproduction, larval rearing and mariculture of Pinctada maxima(Jameson) were then established, which laid the foundation for the development of big pearl industry.
The pearl cultivation with nucleus insertion technique was developed successfully in 1981. The first commercial big pearl was produced (size: 19.0 mm*15.5 mm, weight: 6 g, color: silvery white, shape: grape). This achievement has been popularized and applied in South China widely.
Artificial Pond Breeding of Bighead (Aristichthys nobilis, Richardson, 1844) and Silver Carp (Hypophthalmichthys molitrix, Valenciennes,1844)
The project was awarded National Science Committee Invention Award in 1965, National Science Congress Award in 1978 and Science Congress Award of Guangdong Province in 1979.
The project was started from the research on the artificial breeding of the pond-cultured fish in 1953. In June of 1958, the bighead and silver carp cultured in the pond spawned and hatched successfully after the flow-water stimulation and pituitary hormone injection. Then, Myulopharyngodon picens, Ctenopharynfodon idellus and Cirrhiua molitorella were bred artificially with these techniques. Artificial breeding of domesticated fish was not only pioneering work but also a great invention of aquaculture science and technology in the world; it had changed the fry production method of domesticated fish, which depended on fishing in rivers for the past thousands of years, and contributed greatly to the rapid development of the freshwater culture in China.

Research and Application of Deep-Water Anti-Wave Cage
The project of “Research and application of deep-water anti-wave cage” lays a foundation for the research on technology of deep-water anti-wave cage, which makes China become one of the few countries which comprehensively master deep-water cage technology, promoting the development of mariculture. Moreover, breakthrough has been achieved in studies on the global problem of fishing gears’ hydrodynamic properties which are more complicated than stiffened structure in ocean engineering. Since we first developed water modeling system in China, the country’s ability of design and manufacture of deep-water cage has been greatly improved.
This achievement can be applied in everywhere in South China and other important coastal provinces in China. Compared with similar cages in foreign countries, the deep-water anti-wave cage we developed has the following advantages: typhoon-resistant ability (Class 14) is much better than Norway’s (Class 10); anti-wave ability (4~6 m) is better than Norway’s (3~5 m); anti-current ability (0.75 m/sec) is better than Norway’s (0.45 m/sec). Until 2011 July, 3612 HDPE-C43 and HDPE-C60 deep-water cages have been used in South China, having saved 1.92 billion Yuan. Cumulative new economic effects of over 5.572 billion Yuan has been generated by cage manufacture and cage culture. This project has achieved 14 state authorized patents, among which two are registered by software copyright. All patents have been applied in industrial development and utilization. Based on the project, two provincial guidelines were made, one book was published, 36 papers were published in core journals, and three provincial or ministry demonstration bases for deep-water cage culture were established.
