The Research About The Facility Fishery Micro-climate Mechanism And Theirs Influence On Aquatic Animals

The reason of Chinese fishery developing rapidly, the total output of the aquaticproducts is from 4,650,000t of 1978 to 42,789,900t in 2000, besides China hasconfirmed correct fishery tactics and policy of development, an important factor isthat the scientific and technological progress plays an important role to fishery'sdevelopment. Gross output value contribution rate of the aquatic products of fishery'sscientific and technological progress is 42%, 46% respectively during the SeventhFive-Year plan period and the State's Eighth Five-Year Plan period. The fishery of facilities utilize engineering and industrialized mode of production,set up modernized fishery facilities, offer the best environment of artificial control forthe fact that fishery's economic variety grows, and make it in the most economicgrowth space, obtain supreme output, best quality and a kind of high-efficient fisheryof the greatest economic benefits. The main characteristic of the fishery of facilities is,production goes on under the condition with relatively controllable environment, themode of production is a factory, intensivism, modernization, the target of productionis high cost efficiency variety or special aquatic products, products can produce whilebeing seasonal anniversary to realize, not ultra to list proportionally. The fishery offacilities depends on the scientific and technological progress and forms the newhigh-tech industry, realize traditional fishery to modernized fishery, managed to theintensive management to change from the extensive type, utilizes the limited waterresource and less workforces, brings into play the greatest growth latent energy ofliving beings, and produces more aquatic products by effective way. The fishery offacilities is new technical revolution on the development history of aquatic productsindustry of our country, which is the only way to realize fishery's industrialization andmodernized. The way of facility aquaculture is much comparatively. This paper mainly talkabout the warm flowing water of remaining energy of power plant and the factorygreenhouse of aquatic cultivates. This full text circumfuse two cultivate modes andresearch theirs micro-climate characteristic(mainly including temperature,illumination and water quality mainly). About the mode of warm flowing water of remaining energy of power plant, thispaper mainly research: â‘ The difference analyzing of water temperature amongdifferent positions and different layers of water in the same cultivated pool; â‘¡Thedifference analyzing of water temperature in different cultivated pool; â‘¢Change lawof the water temperature in the ditch; â‘£The relation between average watertemperature of cultivated pool and the infall water temperature of the source of hotwater and atmospHere temperature.The result indicates that the water temperature ofthe warm flowing water in the cultivated pool is directed by the infall watertemperature of the source of hot water mainly, the water temperature in the cultivatedpool is highest in the afternoon; To the same cultivated pool, infall water temperatureis always the highest, outlet water temperature is the lowest. At the same time, upperstrata water temperature is higher than the temperature of lower floor in cultivatingthe pool; The water temperature change is remarkable dependence to the enter watertemperature of the source of aquatic products animal.
