There is just a limited amount of oxygen that water can maintain on to. Several elements that decide this limit are atmospheric pressure, salinity and also temperatures. Within an environmental process oxygen is combined with water by means of atmospheric dissemination at the surface, through flow of wind and also by photosynthesis. Photosynthesis is accountable for a large amount of oxygen contained in water. Additionally, a rise in the atmospheric pressure and a steady reduction in the heat range and salinity of the water improve the content of oxygen. The oxygen in water is calculated in mg per litre. There are various factors that are the cause of oxygen exhaustion. The required quantity of dissolved oxygen in water must not be under 3mg/l to aid aquatic life. Usually the exhaustion of Oxygen are connected with: Moist, Cloudy and also hot weather that commences during the toe end of July and even extends around the start of September. Not just that, however it seems that a higher temperature of water equal to eighty six degrees Fahrenheit or higher as well reduces water's oxygen holding capability. If the sky is full of clouds, then the photosynthesis process is ceased and oxygen synthesis does not occur. Wind can not cease the circulation of fish ponds and limits surface area dissemination of atmospheric oxygen. The real reason for the reduction in oxygen content while the water is retained at higher temperature is because of the greater metabolic activity in fishes. Commonly fishes are cold blooded; therefore their activities and body temperature are regulated by water temperature. Thus during the hottest months of summer season fish biomass and their demand for oxygen are usually greater. To tackle this problem directly we advise the use of farm pond aerator . Sudden algae bloom or death of phytoplankton can easily be caused if there is not an adequate amount of light for photosynthesis to occur, but bloom senescence and insufficient pond nutrients may also be a cause. Oxygen is reduced when dead phytoplankton is decomposed. A big phytoplankton bloom can consume the complete oxygen from the water for respiratory purpose. Colour of water turns to dark whenever a bloom crash causes. Pond layering. The upper level that 4 to 6 feet of the 8 feet or higher deep ponds gets hotter easily during summer season and becomes lighter in weight than deep level water. The top layer is of course lighter as well as hotter and it can't mix with the deep and cool water. The cold water near the bottom level becomes stagnant and the oxygen is lowered due to which the bacteria found in water create harmful toxins and thus causing decomposing organic matter. However, whenever a heavy or cold rain flows down, water is mixed up fully. The water in the absolute depths and at a much lower temperature replaces the liquid in the surface. This is more dangerous because the oxygen content in the depths was decreased thus causing difficulties to the fishes. Decaying of organic waste. When the overall weight of fish gets raises in commercial ponds during summer, the wastes of fish and organic loads get high. However, these will need to break down. This decomposition process takes place with the help of oxygen. Additionally, extremely high content of waste materials can result in growth of algae. To considerably improve each difficulty stated previously the better solution is pond aerator solar , which we will discuss thoroughly within the next article.
