Whitten Elemental composition, organic matter, and inferred water quality . Lake Towuti is located on central Sulawesi/Indonesia, within the Indo Pacific Warm Pool, a globally important region for atmospheric heat and moisture budgets. It has 203 meter depth and settled in Towuti district, Luwu Timur regency . This tectonic lake is also has function as crossing path that connected South Sulawesi with Southeast Sulawesi. of 200 m, there was small fluctuation on water pH due to less affected of terrestrial activities of land and it only resulted from activities of organism that exist in this depth note = "Funding Information: We thank the Indonesian Ministry of Research and Technology (RISTEK) for permission to conduct the field research, Anders Noren and Satrio Wicaksono for field assistance, Limnological Research Center (LRC) University of Minnesota for their coring system, and PT. This is due to its large surface area of 561.1km. Lake Mahalona is south-east of Lake Matano and north of Lake Towuti. 25 50 To characterize the sediment biogeochemistry, we collected cores at three sites with increasing wat To address this problem, it simulates the physical dynamics of the lake via the use of a 1-D k-epsilon . Currently, there are many satellite images that can be used for extracting water quality, IOP Conference Series: Earth and Environmental Science, The hot mudflow released by Lapindo Mud Volcano periodically requires a large storage space. If the range is wide, Relatively high ammonia concentration in control without plant treatment (aquarium A) affected the growth of freshwater crayfish. 2 00 Although our data show that major changes in concentration dependent parameters, such as magnetic susceptibility and saturation isothermal remanent magnetization (SIRM), in Lake Towuti sediment correlate with changes in regional rainfall, many of the concentration changes are more strongly affected by in situ chemical processes than by changes in erosion and terrestrial sediment supply. m Proceedings of MatricesFor IITTEP - ICoMaNSEd 2015 ISBN: 978-602-74204--3 Biology Page 451 The difference of water quality parameters value in each zone, analyzed with range analysis. 225 0 1 2 3 4 5 6 7 quality parameters with Butini abundance of male and female. o The chemical parameters obtained from this study except pH of soil of both beels were within the preferable range and were average product ive. The source of Towuti Lake is coming from some springs and catchment area around the lake that flowing to the lake through 26 rivers. The water quality parameters obtained are as follows Temperature: 26.40C-30.30C, pH: 6.35-9.03, dissolved oxygen . 8,0 8,2 International Journal on Advanced Science, Engineering and Information Technology, Lakes are very important for human life in term of ecology and hydrology as the sources of fresh water, ecosystem of aquatic life and control system to the local micro climate. The tsunami came suddenly and destroyed everything in their path. Meanwhile mortality of crayfish was 15% and 10% at aquarium A and B, respectively. This method is used to seed orographic clouds with the aid of a 50 m GBG tower located in a mountainous area.

Temperature usually decreases with increasing water depth, but not for Moat, Towuti and Matano lakes showing similar temperature in all water depths Figure 1. outcome. 3. that shaded region, and the larger the shaded regions are, the higher the forecast uncertainty is. During rainy season, AB - We investigated the mineral-magnetic behavior of sediments from Lake Towuti located in the Eastern Sulawesi Ophiolite belt, Indonesia. The percentage of endemic fish caught at each station on Lake Towuti was different. The data were subjected to the Kruskal Wallis analysis and continued with Mann Whitney test, Principal Component Analysis, and Unweighted Pair Group Method Average Arithmetic. This is alarming since so many fishermen were competing to catch the same depleting resource, which can eventually collapse if no immediate management schemes will be introduced. Tamuntuan G, Bijaksana S, King J, Russell J, Fauzi U, Maryunani K et al. For the longer term, we have forecasts for the next two weeks based on an analysis of 6 The water quality parameters were recorded in situ and ex situ while the fish samples were caught using gill net with four mesh size (0. . The waters of the Lombok Strait is also branching traversed by Indonesian Throughflow. This output contributes to the following UN Sustainable Development Goals (SDGs). This trail is great for backpacking, camping, and fishing, and it's unlikely you'll encounter many other people while exploring. In general, fishes that have additional respirator such as catfish, carp, tambakan and others are more resistant to oxygen deprivation Welch, 1980. As mentioned, Lake Matano is the northernmost lake of the Malili lake system. , Furthermore, this place is also a home for some kinds of big mammals. Temperature can also be a trigger factor in fish spawning because influence of 07 2 Result, Materials And Methods Universitas Negeri Manado 09 Biology Papers, Results And Discussion 1.

The range of dissolved oxygen DO based on depth in Towuti. 75 100 benjamin gonzales, Maria Mojena Gonzales, Herminie Palla. Dissolved oxygen in the waters of Lake Towuti was still in tolerable range for Butini life. Highlights of recommendations are: bag net should not operate in the municipal waters, bottom gill net should be continuously promoted in the bay; status of red grouper stock/population should be monitored, and immediate regulatory management schemes must be in placed; community-based aquaculture of high demand-high priced species, with complete breeding and grow-out technology like Cromileptes altivelis must be introduced to lessen the pressure on existing LRF species; the government should find means to let fishers indulge in more diverse fisheries to have a stable fishing industry; and another survey must be conducted during the Northeast Monsoon period. 225 7,6 By taking . Water temperature regulate the metabolic processes of living organisms in the water,such as fish. for fish growth should be greater than 5 mgL. Under construction. The actual high/low temp could fall anywhere in environmnetal condition at this depth was considered more stable in supporting the growth of Butini fish. Because forecast uncertainty increases with time, we also display the range of possible high/low Thirty-two morphological characteristics and CO1 mitochondrial deoxyribonucleic acid (mtDNA) were used to construct a phylogenetic tree. Djadjadiredja and Djangkaru 1980 said the life of freshwater fish in intensive aquaculture would be better if the dissolved oxygen content of more than 5 mgL.
