The technology of the solar pond project realizes the integrated heating of the protective-styled cultivation of the aquatic products for the first time in the Northern coastal area of China. In the process of the over-wintering production of the cultivation objects, the percentage of solar energy supply is 100%. In the process of cultivation in spring, the contribution percentage of solar energy achieves more than 70%. It achieves the industrialized development preliminarily. Technology of high-health cultivation is developed in the mechanism of the operation of brine solar pond. The production line of bio-baits of mono-cellular algae is used in shallow-styled solar pond. The production line of heat-integration, the technology of over-wintering and cultivation and developing commodities are used in the conservatory-modeled solar pond. The system can endure power 11 wind in the integrating process and can save energy of 100 tons each year.

4. The prospect of application and dissemination

With the support of the heat-supply system of the integrated solar pond project, the protection-styled cultivation of super cultivation objects of sea water is carried out in the coastal tidal-flat area and saline and alkaline land, such as fish, shrimps, crabs and shellfish. With the help of technology, high-health cultivation objects of sea water are reproduced and cultivated. It creates high-efficiency technology in the conservatory shed. It opens up a new way of adjusting the industrial make-up of agriculture in the coastal rural area of China. Marvelous prospect of application and dissemination is demonstrated in the experiment.

The coastline of China is 18000 kilometers long. The tidal-flat and saline and alkaline land is broad and wide. The advantages make it suitable for the multipurpose industrialized development in large scale.

4.1 Pursue the scheme of on-the-sea pasture of solar pond project.

In the offshore gulf of the Bo hai Sea, the Huang hai Sea and the East China Sea, (center on the sea with a depth of -10m), mechanism of the solar pond is used to transform the environment of the fishery, to improve water temperature in the sea area, to prolong the growth period of breeds, to change the migration of bio-population and eventually to develop on-the-sea pasture of solar pond.

4.2 Implement fishery project scheme of land sunlight.

In the coastal seashore north of Fu jian Province, brine or sea water is adopted to build a large-scaled over-wintering field of solar pond for fish, shrimps, crabs and shellfish. With the support of green sunlight system, modern technology of water treatment and modern biotechnology, an industrial belt of the sunlight project about high-health fishery is built along the coast.

4.3 Develop sunlight industry of high protein

In the coastal seashore and beside the inland salt lake, industry of high protein is developed. Brine worm powder is a kind of additive with low cost, high quality and rich nourishment in the field of new food. The content of dried protein is above 60%. Worm eggs are used as baits for young fish and shrimps widely. The worm can survive in a wide range of temperature and salt concentration. The temperature from 3"C to 40"C and salt concentration from 5%o to 120%o are all suitable for them. Growth period of brine worms can be prolonged with the development of protective cultivation of brine worms in solar pond. Brine worms and worm eggs can also be raped in winter. The content of dried protein in spiral alga is 60%. Spiral alga is a kind of micro-algae of high economic value. It is a key development object all over the world and is a future food resource universally admitted. It can also survive in a wide range of temperature and salt concentration. It is distributed in both sea water and fresh water. The percentage of light-conversion is 18%. The ecological environment of the spiral alga is suitable for carrying out protective cultivation production in large scale in the use of solar pond project.

4.4 Study and develop the industrialized production technique of lithium bromide

The integration technology of solar pond is fit for all the protective cultivation of aquatic living things in the sea. People should carry out multi-purpose development and application creatively according to the various natural conditions.

In a word, the issue has already showed outstanding prospect in the experiment and research. The economic benefit can be increased greatly with the popularization of the technique in the coastal area of China.

It is estimated that in the future research and development of the coastal solar pond, great technical breakthrough will be made with the joint effort of the scientists all over the world and by way of modern technology in the aspect of constructing ponds, establishing and maintaining salt gradients, forming and maintaining temperature field, simulating bio and ecological environment, reproducing and cultivating bio-population and so on. It will be made more scientific and perfect. It can be fully believed that building the modern aquatic cultivation industry in the protection-styled solar pond all over the world, developing coastal solar pond project with complete functions, rational distribution and scientific structure and building up on-the-sea blue agriculture will surely come true in the near future.
