Urban lakes are experiencing various kinds of problems because of the anthropocentrism of environmental management. This also happens in Situ Gintung, Indonesia. This lake is polluted by many pollutants from urban activities, such as the entry of domestic waste into waters due to anthropogenic activities and the amount of leftover food not consumed by fisheries. These problems can be solved by observing the water quality of Situ Gintung to provide information about parameters that have exceeded environmental quality standards and provide general information about the water quality in the dry season from 2017 to 2020. The research is done using a purposive sampling method and determining water quality status with the STORET method based on the Indonesian standard with parameters less than ten. As a result, Situ Gintung water is neither classified as class I, II, III, and IV nor be utilized for consumption, recreation, fisheries, and irrigation because the quality status is mostly in the heavily polluted category. Furthermore, the three highest polluters from each class are BOD5, COD, and a total of Coliform.

The effects of fish farming activities on the aquatic environment were evaluated by studying the water quality of twelve rivers located in northeast Spain. Two sampling sites were used for each river: the first sampling point was located just upstream from the fish farming facilities and the second one was downstream from fish farm effluent discharge point. In order to avoid any misinterpretation due to watershed location and seasonality, a stratified statistical analysis was performed. The results show significant decreases in pH and dissolved oxygen, in contrast to chemical oxygen demand, ammonia, phosphates and microbiological parameters, which significantly increased downstream from the fish farm discharges. Other significant variations were also found for conductivity and temperature. According to the European and local regulations concerning to support fish populations, our results fell within the allowable limits for salmonid waters. Nevertheless, we suggest that further investigations should be carried out to study the ecological interactions between farmed and wild fish populations.
