Effect of Cage Aquiculture on Eutrophication in Luoma Lake

According to results of the 1998 study on nutrient input from cage aquiculture into Luoma Lake,the input of nitrogen and phosphorus was 339 and 57 t,respectively,accounting for 27% and 33% of the total input,respectively, indicating the effect of cage aquiculture on eutrophication of the waterbody of Luoma Lake.Moreover,the analysis of the variation in water surface area and the yield of the cage aquiculture in the lake in the past 10 years revealed that the area of cage aquiculture tended to be stable after 1995 and so did the effect of the aquiculture on eutrophication of the waterbody of Luoma Lake.
