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.
