“…Oxygen is one of the limiting factors, so if its availability in the water is not sufficient for the needs of aquatic organisms, all activities of the organisms will be hindered. Sources of dissolved oxygen can come from the diffusion of oxygen in the atmosphere and photosynthetic activity by aquatic plants and phytoplankton [34].…”

Tilapia (Oreochromis niloticus) is a fish native to Indonesian waters which has spread to Southeast Asia and China. Tilapia is generally cultivated in fresh waters, but due to the high demand adaptation of tilapia cultivation in brackishwater is also conducted. The purpose of the study was to determine the analysis of high protein feed in rearing Tilapia (Oreochromis niloticus) broodstock in brackishwater culture. The research method included the data collection of specific daily growth rate parameters and survival values. The content of protein used in feed was 35%. The results included the value of the specific daily growth rate of tilapia (Oreochromis niloticus) broodstock of 0.0102% and a survival value of 100%. The water quality was in the temperature range of 27-33oC, pH of 6-8, DO of 3.26-6.38 mg/L, and salinity of 0-5 ppt. The study was influenced by several factors including pond preparation, broodstock preparation, broodstock selection, broodstock feeding, water quality management, and pest and disease control.

“…Growth in environmental awareness in the latest years has caused new perceptions of water quality and the monitoring trends are in a progress. The Water Pollution Control Act Amendments in 1972, or Clean Water Act (CWA), marked one of the maximum far-reaching environmental legislative acts to resolve environmental problems (Novotny and Olem, 1994;Copeland, 1999). Pollution, described as any human-induced change to the surroundings, originates from either a factor supply or a nonpoint supply, and the bulk of the cleanup is targeted upon sewage and domestic wastewater discharge factor sources and their effect on ingesting water (Hun, 1998).…”

Most developing nations are known for having a rapidly growing population. This hastily increasing populous and modifications for agricultural expansion which has been adversely degrading the surroundings. Consequently, ongoing pollutants have been discharging into the water bodies with broad scopes that are seen as troublesome and degrade water quality. Benthic macroinvertebrates are susceptible to a variety of variables within a watershed, and water quality parameters. Pollution influences the invertebrate network through changing water movement, habitat, meal quality, and oxygen availability. Thus, the efforts of biological evaluation will permit the improvement of relationships between benthic stressors and the benthic community.

“…While the point-source pollution has been effectively controlled in most regions, the non-point source pollution in complex urban environments becomes an increasingly important concern [4]. Statistics show that urban non-point source pollution has become the second largest non-point source pollution [5].…”

Urban non-point source pollution is becoming a serious issue under the context of rapid urbanization and its impacts on surface hydrologic processes. The identification of non-point source risk areas and the effectiveness of source-control measures provides important first steps to improve the degrading aquatic environment but is challenged by the complex dynamics and variabilities of surface pollutants in urban environments. In this study, we investigate the spatial and temporal variabilities of non-point source pollution in a small urban catchment based on numerical simulations and in-situ samplings. Our results show that residential, industrial, and commercial land contribute to the most pollutant loadings and are the main constituents of the pollution risk area. Rainfall duration and intensity are the main factors in determining the temporal variations of urban non-point source pollution. There is no correlation between early drought days and pollution load. Numerical simulations show that it is more effective to increase urban vegetation coverage than to enhance road cleaning for effective non-surface pollution control. For enhanced road cleaning, it is more effective to improve the frequency of road cleaning than its efficiency. Our results provide important guidance for effective controls of non-point source pollution as well as the establishment of long-term surface pollutant monitoring network in complex urban environments.
