VERTICAL-HORIZONTAL WATER QUALITY PROFILES OF BATUR LAKE, BANGLI DISTRICT, BALI SUPPORTING SUSTAINABLE LAKE MANAGEMENT, Indonesian Aquaculture Journal Vol.7 No.2, 2012



Batur Lake located in Bangli District is one of fisheries-basedregions in Bali with niletilapia as the main cultured species. Monitoring on environmental conditions of the lake was carried out to get the vertical and horizontal water quality profiles of the lake. Climatology condition of the area was also presented in the study. The study area were between 8 o 13’- 8 o 18’ S and 115 o 22’ - 115 o 26’ E. Field survey was done with random and transect sampling points distribution. The water quality monitored in the lake essenti al ly cover s important parameters such as depth, tr anspar ency, temperature, pH, dissolved oxygen, salinity, nutrients (ammonia, nitrate, nitrite, and phosphate), sulfide, chlorophyll, and planktonic composition. Results of spatial analysis (vertically and hori zontal ly) of water quality i ndi cated that oxyg en concentration up to 10 m deep is still appropriate for nile tilapia culture. Nutrient (phosphate, ammonia, nitrate, and nitrite) contents of the lake meet the standard levels set by Ministry of Environment of Indonesia, and were still suitable for aquaculture operation at depth 7 10 m. From climatology point of view, it is known that the extreme climate occurred in June-August resulting in water mass changes, thus, affecting aquaculture sustainability in the lake.
