| Abstract: | To improve the water ability of purification and disease prevention in the culture of Anguilla anguilla,a diversity of biological water structures was established by regulating water qualities combined with the application of ecology theory,which greatly decreased the consumption of water and drugs,improved the feed efficiency and reduced the cost in the process of culture.A total of 961188 glass eels were feed for 280 days,then 54890 kilograms of Anguilla anguilla with an average weight of 59 grams were harvested and the survival rate was 97.8%.Compared to the past years,it was remarkably evident that the cultural time was shortened.The di-sease incidences and feeding cost also declined,with a 12.6% increase of feed efficiency and a 70% decrease of water exchange rate. |
