A good pond aeration system might not be the ultimate solution to all of your pond problems, but making sure that the shrimp pond keeps on being aerated properly is very important and effective to ensure and maintain a healthy pond ecosystem. In addition to that, making sure of the presence of a good aeration system is a relatively affordable thing to do to prevent any problems that threaten every health aspect of your shrimp pond.
What is an aerator?
In general, aeration is defined as taking air from outside the pool and making it dissolve into the water. Some aeration should be designed in each pool from the beginning, usually in the form of water fountains or waterfalls. This works quite well, as splashing the surface of the pool from above with water is effective in getting air into the water. Aeration system designed as such also tends to produce at least the minimum amount of air ideal for the pond to remain healthy. For large-size ponds or ponds with a shape that is “unusual”, adding proper aerators is highly suggested.
The way aerators work is simple. This device consists of an air pump that forces air from outside the pond down through a hose to the dispersion unit at the bottom of the pond and sends a flow of bubbles into the pond. The bubbles that rise serve to circulate the water and dissolve air into the water.
Reasons why shrimp farmers need to start good pool aeration
1) Aeration reduces pool debris
Along with the increasing age of the pool, nutrients accumulate in the base of the pool and are turned into dirt. Impurities are not only annoying to be seen or felt, but also can cause a pungent, unpleasant smell and become the habitat of leeches. Aeration is important because it combats dirt and other decomposed wastes by increasing dissolved oxygen and circulating water. Aerated pond encourages the colonization of aerobic bacteria that consume nutrients to reduce the buildup of dirt that exists and prevent the buildup of additional ones in the future.
2) Aeration improves water quality
Nutrients are not only accumulated at the bottom of the pond into the dirt but can also be trapped in the water column causing the pond to look cloudy. By reducing impurities and excess nutrients, increasing oxygen, and circulating water, aeration will improve the quality and clarity of the water. Besides, from the aeration of pond water, it can be seen that there is a reduction in algae and weeds because there will not be a lot of nutrients to encourage their growth.
3) Aeration increases dissolved oxygen levels
Oxygen from pond water aeration is not only needed to sustain the survival of shrimp, but also the good bacteria. Aeration is important because, without oxygen, the pond will experience anaerobic conditions. Anaerobic bacteria don’t efficiently decompose organic material as aerobic ones do. Besides that, anaerobic bacteria produce carbon dioxide and hydrogen sulfide when digesting the material organically, creating the source of the pungent smell. Aerobic bacteria, on the other hand, are beneficial to produce gas that is not harmful when breaking down dirt. Introducing aeration into the pond increases the amount of dissolved oxygen in the water that makes the pond function as a healthy aerobic system.
What is the function of aerators for shrimp farmers and ponds?
The main and most important function of aeration is the oxygenation of the water. Dissolved oxygen plays an important role in a healthy pond ecosystem. Not only shrimp that need oxygen to stay alive, but various useful bacteria also do. Bacteria both serve to eliminate pollutants, organic dirt, and the waste that is produced by shrimp. Without a sufficient amount of oxygen in the water, good bacteria will not be able to work as efficiently. This will make the shrimp pond less clean and less healthy.
The process of oxygenation of an embankment is more effective with an aerator also means that the level of oxygen dissolved in the pond farms can remain consistent. Levels of oxygen that are not consistently caused by aeration are not sufficient, which is then exacerbated by various factors from inside and outside of an embankment. Fluctuations in temperature cause the water to hold over much or more little oxygen dissolved. The movement of water that is lost due to electrical die and so on also can cause a drop in big on the level of oxygen. Besides that, natural factors like rain also could disrupt levels of oxygen dissolved being required, which can create a stressful living environment for shrimp.
2) Improve circulation
In addition to aeration, water circulation is also important to note as part of the design of a good shrimp pond. How to work the aerator is to rotate the water pond that entry of water fountains, which then flows through the pond into the box skimmer or intake filtration, which sends it back to the water fountain. It creates a channel for the movement of the water that is supposed to work with both the circulating water in swimming ponds. Most of the shrimp ponds will have two zones die primary in which the water circulates it less effectively. First, unless the pond is designed in a specific way, there will be areas with less circulated water than others, such as angles and bays. Secondly, and that is more important, the water tends to flow in along the third part on the pool of water fountains and a skimmer. Water that is more in than shrimp pond will get circulation that much more slightly.
Each bubble being added to the pond will add vector circulation of water from the base to the top of an embankment. This process directly reduces the “dead zones” in the shrimp pond, in which the pollutants and debris will settle and contribute to the layer of a mud pond. Vectors circulation up also complicates the channel movement of water there, which helps encourage circulation to the area to die at around the edge of an embankment. All movement of water is preventing the excessive growth of algae and the larvae of mosquitoes in the area that is stagnant at an embankment.
3) Breaking surface tension
Bubbles generated from the aerator do not just circulate water, but also broke the tension surface of the pool which produces some beneficial effects. First, the effects are preventing some insects that often arise in an embankment, especially mosquitoes that use the pond to spawn. A lower voltage level also facilitates the exchange of gas between an embankment and the air in the vicinity, which emits carbon dioxide that is produced by shrimp and is the cause of some pollutants being released.
Aeration may not be the main solution for all pond problems, but aeration can solve many problems in the pond and be a good preventive measure for bigger and more complicated problems. To ensure the shrimp pond remains healthy and reduce additional costs to solve problems in the future, aeration is an important thing to be considered and applied by every shrimp farmer.
