How to reduce the cost of shrimp farming

This is just one of the main issues that are very effective in reducing the cost of shrimp farming, we hope to help you a lot to harvest shrimp.

Control food stocks
Food stock is one of the most important determinants of production cost (about 50-60%). The amount of food lost in water and mud is around 20%. This amount of residual food decomposes nutrients for algae to thrive and the pond bottom is dirty due to residues. These substances will consume oxygen and produce a lot of toxic gases such as NH3, H2S … Shrimps will show symptoms such as head drop, eating less, black gills, bad pigment,… This is when diseases occur due to the growing of harmful bacteria.

The feed conversion ratio depends on quality, environment and experience in food management. The avarage time for shirpms to consume food is usually 2 to 3.5 hours. Therefore, it is possible to feed shrimps several times a day (4-5 times), which accounts for 80% of the daily shrimp intake. Shrimp will eat a lot during sunrise and sunset, so you need to increase the amount of food during the day and reduce during night time. When the shrimps are peeling, cold weather, rain, sun light or dramatic change in the pond’s environment, you should reduce the amount of food.

Process food through the feeder is a basic solution with relative accuracy, so it is important to see the ability to function, health status, food consumption level, water transparency,..

Paying attention about farming density
Fully stocked densities with adequate investment and equipment such as water fans, bottom oxygen (if any) to ensure dissolved oxygen in the pond> 4 mg / l for black tiger shrimp and> 5 mg Per liter for PT. Implement preventive measures from pond preparation and throughout the culture process. Creating and maintaining a reasonable phytoplankton system in ponds is of paramount importance: creating a natural food source for shrimp, creating oxygen for the pond, preventing the growth of algae and making the environment Water is less in, less fluctuate, shrimps are shocked, increased survival rate, creating conditions for shrimp to increase the ability to catch prey, rapid development.

Use of chemicals
Drugs, chemicals, probiotics are relatively expensive (20 – 30%). In order to save on this cost, it is necessary to closely monitor the ponds’ development so that it is planned to use drugs and chemicals in a timely manner, at the right dosage, creating a safe and sustainable pond environment for the crops. The next production has a chance of success.
