NOVELTY - The device has an electric heating boiler for controlling breeding temperature in a cultivation pool by using a plastic thin film solar energy pipeline. An open circulation ecological system is provided with a completely closed loop circulation ecological system.    USE - Totally enclosed full-euphoticintelligent organic prawn ecological cultivation device for use in a municipal market and an industrial factory.    ADVANTAGE - The device reduces cultivation difficulties, and has low death rate, high yield, high prawn quality, prolonged service life and high survival rate. The device is inexpensive. The device timely and accurately regulates and controls water illumination, light quality, temperature, salinity, dissolved oxygen level, nutrition salt level, carbon dioxide level, pH value, transparency, ammonia nitrogen content, nitrite content, hydrogen sulfide content, organic matter, environmentalperformanceindex, substrate anoxic degradation, bacterial viral disease, stress reaction, antibiotic residue and medicine residue so as to maintain specific illumination condition in an intelligent manner. The device satisfies wide application range requirements. The device reduces cultivation risk and increases operation profit. The device performs prawn ecological cultivation process in an automatic manner. The device is convenient and quick to manufacture and mount. The device reduces cultivation tank modify cost and avoids loss of carbon dioxide, oxygen and nutrition element. The plastic thin film pipeline is utilized for pouring water so as to enhance greenhouse heat absorber effect. The device utilizes solar energy to remove ammonia nitrogen, nitrite, sulfured hydrogen, bait, excrement, waste metabolites and biological remains in water by using photosynthetic germ. The device converts nutrition element into live bait material so as to reduce water organic load. The device reduces water loss caused by evaporation. The device increases water body cultivation density and cultivation material utilization efficiency. The device protects prawns from local over-dense hypoxia prawn condition.    DETAILED DESCRIPTION - The cultivation pool is made of clay, steel, cement, concrete, masonry and a plastic film. The plastic film comprises a polyethylene plastic thin film and a high molecular material thin film, and is made of high light-transmitting resin, PVC, polypropylene, polystyrene, polymethyl methacrylate, polycarbonate, organic glass, acryl material, silicate glass and high transparent material.
