Cage fish culture and reservoir water quality of the relationship between research Abstract: reservoir resources in China is very rich, and the rapid development of the reservoir cage culture, but the prevalence of the development of the disorder, regulatory delays, deterioration of water quality problems. Cage culture and the relationship of the reservoir water quality changes, and put forward to maintain reservoir water ecosystems benign The balance some suggestions. Keywords: cage culture, reservoir water quality, mutual relations, it is recommended Our existing 8900 Block various types of reservoirs, with a total water surface of more than 2 million hectares, accounting for 11.5% of the total water surface of fresh water, which fish the water is estimated at more than 1.8 million hectares, accounting for 32% of the national freshwater can be raised on the surface of the water reservoir for agricultural irrigation, drinking water, fish farming area, cage culture is a high input, high output, large water fisheries, with less investment, high yield, quick features, Reservoir cages farming can be the most economical and maximize the use of the existing reservoir of resources, but with the expansion of the scale of farming and farming intensity, cage culture highlights on the the reservoir ecological environment impact farming bait, excrement, fishery drugs, dead fish, life waste and other serious damage to the ecosystem of the reservoir, from early 2006 to the end of 2007, we conducted field research Guangxi reservoir cage culture, explore the relationship of the reservoir cage culture changes in water quality. 1 Cage Culture on Water Environment The waters of the reservoir is a complete ecosystem, fish cage culture system will break the original balance, feeding-culture system while increasing the total amount of fish populations, huge investments bait on the non-feeding formula farming, the system increases the filter-feeding fish populations total
