Why do shrimp and fish farming at high densities often use aerators in the water?
The aquaculture industry can be said to be a very popular industry in our country. But in the farming process, there are no fewer risks. The problem of lack of dissolved oxygen in water is one of the major risks in the development of farmed animals.
I. Signs that ponds are lacking oxygen
Oxygen is lacking but still enough to sustain: the creatures in the pond only appear in the early morning, and when the sun rises, their heads stop rising. If you look specifically at fish, you will see fish and shrimps gasp for air above the water surface. But there is a noise at the edge or when we go near they will shake their body and dive.
Oxygen is seriously lacking: Fish and shrimps will float their heads both at night and during the day. Even if we go near them, they will not dive down, even when the sun comes up, the fish will still float their heads.
The need for oxygen in aquaculture.
High oxygen content leads to increased growth rates of fish and shrimps, stimulating respiration. Researchers have also proven that through many experiments. Oxygen content also affects the prey capture rate of animals in the pond. The more oxygen there is, the faster the fish and shrimps catch prey. This way, development can be promoted quickly.
The higher the oxygen content, the higher the survival and development rate of fish and shrimps. In ponds, animals grow more and more. At some point, the oxygen content will be lost because there are too many individuals living in it. This will lead to the phenomenon of air stripping. Thus, a part of the creatures will die and it will also greatly affect the economy of people in farming.
II. Reasons to use oxygen generators in shrimp and fish farming water
Farming shrimp and fish at high densities, people often use products that provide oxygen into the farming water because: When cultivating shrimps and fish at high densities, it is easy to lack oxygen to supply the respiratory system of shrimps and fish because the concentration of dissolved oxygen in water is low while the density of shrimps and fish is high and the pond area is limited. Therefore, shrimp and fish farming often uses Oxygen-providing products that increase the concentration of dissolved oxygen in water, helping shrimps and fish respire well, thereby growing healthily.
Currently, many pond owners have used shrimp and fish farming equipment to create oxygen for fish and shrimp because this equipment creates oxygen evenly throughout the pond from the water surface to the bottom of the pond to minimize accumulation of organic debris.
III. Effects of using oxygen-providing products in shrimp and fish farming water
Help exchange dissolved oxygen from the outside environment into the water, stimulates the respiration of animals in ponds and lakes, increases the growth ability of aquatic animals, and waves create oxygen, this activity also collect waste and excess food at the edge so it can be easily cleaned.
In a period of technology and modernization like today, there are many products that help with creating oxygen in ponds and lakes. But to create a large amount of gas, enough for organisms to use, Aqua Mina would like to suggest some products including: air blower, turbine aerator, Ventek nano bubble oxygen generator and bottom oxygen system,...
- 1. Turbine aerator
- 1. The circular disc turbine aerator also called the duck leg turbine aerator; is to provide air very effectively and popularly in shrimp and fish farming.
- 2. You can use 1-phase or 3-phase motors. Common capacity options range from 2hp-3hp depending on water depth.
- 3. The machine is used effectively in the stage of large shrimps near harvest time and at night, when shrimps need a lot of oxygen to peel and harden their shells.
- 4.The machine is compact, easy to clean, convenient to move and disassemble.
- 5.In a 500m2 round pond, only 3 turbines and 2 10-blade water fans are needed to ensure oxygen for about 3 tons of shrimp.
- 6.Can be used for cement ponds, composite ponds, iron frame ponds lined with tarpaulin, earthen ponds lined with tarpaulin. Especially for earthen ponds, bottom oxygen systems are always a headache; because sludge can clog oxygen systems, turbine aerator is a good solution for all types of ponds.
- 7.No need to waste time on designing or wiring oxygen pipes, just install and use quickly.
- 8. No need to worry about oxygen pipes being clogged.
- 9.Do not waste too much time cleaning equipment between farming seasons.
- 10. Strong water turning force, reduce water stratification, release toxic gases very effectively.
- 11. Simple assembly, adjustment of rotation direction, and optional oxygen supply.
2. Longtech air blower
Longtech air blowers are distributed by Aqua Mina company and used to supply air to industrial wastewater treatment systems, designed to achieve high efficiency, with stable supply air flow and optimal air pressure, helping to ensure efficient operation and energy saving. Easy to disassemble and clean, helping users save time and maintenance costs.
Good quality meets most of the strict requirements of users. All Longtech products before being shipped go through a strict inspection process according to ISO 9001 standards and CE quality standards.
Providing large amounts of air for waste treatment and drainage plants.
Used for conveyor applications.
Air supply for electroplating industrial applications.
Vacuum applications.
Used in paper, food, cement factories...
3. Ventek nano bubble oxygen generator
With an average bubble size of only 1.6 micrometers (data proven by the Vietnam Military Institute of Science and Technology), VENTEK is one of the tools that helps dissolve oxygen into water, keeping oxygen at a low level. The most effective on the market today. Help shrimps absorb oxygen better, making them healthy and growing 10% faster than traditional methods at a very reasonable cost.
VENTEK nano bubble generator is designed specifically for the seafood industry, the product is designed and manufactured by Huetronics Joint Stock Company; This is an enterprise with more than 34 years of experience in the fields of research and development of electronic products and high-tech clean agriculture.
It is the most effective device to provide nano oxygen particles for high-density shrimp and fish ponds today.
Exclusively distributed by Aqua Mina - 3-year warranty for you to use with peace of mind.
Optimizing the amount of oxygen helps shrimp/fish grow faster during the harvesting stage - replacing the bottom air blowing system, saving costs up to 50%.
4. Bottom oxygen system
Dissolved oxygen is a necessary condition for shrimp and fish to breathe and maintain life in the water environment.
Smooth air distribution throughout the bottom of the pond when combined with a water fan system will create very good flow.
The bottom layer air flow when in contact with the water fan system creates convection and mixes without causing water stratification, ensuring that the environment in the pond is the same as the water surface and the bottom layer.
Oxygen at the bottom layer is very important, releasing toxic gases at the bottom of the pond to escape to the surface of the water and follow the escaping air.
The abundant dissolved oxygen content in the bottom layer helps beneficial microorganisms grow and decompose organic waste.
When feeding shrimp, turn off the water fan and still have the bottom oxygen system providing oxygen for shrimp and fish to operate, catch prey, and digest food.
- Through the information shared above, TOMMY hopes to help people see that providing oxygen for aquaculture (shrimp and fish) is very important, so it is necessary to have these devices to help cultivate shrimp and fish better.
