Shrimp fry stocking is a crucial stage at the start of the shrimp farming cycle. Farmers need to choose the proper stocking method since it affects shrimp survival and growth throughout the farming cycle.
The proper shrimp fry stocking method reduces stress on the fry, increases shrimp survival rate, and minimizes the harmful impacts of shrimp diseases. In the long term, choosing the proper shrimp fry stocking method can help farmers avoid financial losses.
One of the tools farmers can use to conduct shrimp fry stocking is a conical tank. What is a conical tank and what are its advantages? What are the steps for stocking shrimp fry using a conical tank? Find the answers in the discussion below.
Shrimp Fry Stocking Method Using Conical Tanks
A conical tank is a cone-shaped tank used as a temporary place for acclimatizing shrimp fry with pond water before they are stocked. The use of conical tanks in the process of stocking shrimp fry ensures that the fry steadily adapt to pond conditions, including changes in salinity, temperature, and pH levels.
Stocking shrimp fry with conical tanks aims to save energy and labor needed. This tool is typically used when there are many shrimp fry to stock and the area of the pond is quite large.
The Advantages of Stocking Shrimp Fry Using the Conical Tank Method
Conical tanks have several advantages, particularly in supporting the shrimp fry stocking process at the beginning of farming cycle:
- Helping shrimp fry to steadily adapt to farm environmental changes.
- Reducing the risk of stress and mortality due to sudden temperature and salinity changes.
- Ensuring optimal dispersal of shrimp fry in the pond.
6 Steps of Shrimp Fry Stocking Using Conical Tanks
Shrimp fry stocking using conical tanks is conducted through six key steps, namely
1. Conical Tank Preparation
First, choose an inverted cone-shaped container or tank with an outlet at the bottom to drain water and shrimp fry into the pond. This container is known as a conical tank. After that, fill the conical tank with seawater or pond water at the ideal temperature, salinity, dissolved oxygen (DO), and pH for the fry.
2. Acclimatization Process
Slowly place the shrimp fry in the conical tank. Add water from the pond to the conical tank gradually every 10–15 minutes to adjust the temperature and salinity. Acclimatization typically takes 30–60 minutes, depending on the salinity and temperature differences between the shrimp fry’s original water source and the pond water.
3. Aeration
Make sure the aeration in the conical tank is adequate to maintain the DO concentration. Use an aerator with fine bubbles to avoid creating a strong current that may trigger stress on the shrimp fry.
4. Shrimp Fry Observation
During the acclimatization process, observe the fry’s activities to ensure they are not weak or stressed. Healthy shrimp fry usually swim actively and respond to stimuli.
5. Shrimp Fry Stocking to the Rearing Pond
If the conical tank’s water quality parameters are close to the pond water conditions, you can start stocking the shrimp fry. Open the outlet at the bottom of the conical tank to slowly release the shrimp fry into the pond. To avoid extreme temperatures, make sure to stock at the optimal time, such as in the morning or evening.
6. Post-Stocking Shrimp Fry Monitoring
Monitor the shrimp fry’s condition in the pond for the first few hours after stocking. Pay attention to the fry’s activity and ensure that they continue to swim actively and respond to stimuli in the pond.
Conclusion
A conical tank is a tool that can be used for the shrimp stocking process. The method of shrimp fry stocking using this cone-shaped tank has several advantages, including
- Helping shrimp fry to steadily adapt to farm environmental changes.
- Reducing the risk of stress and mortality due to sudden temperature and salinity changes.
- Ensuring optimal dispersal of shrimp fry in the pond.
The process of stocking shrimp fry using a conical tank is likewise relatively simple, summarized in the following six steps:
- Conical tank preparation
- Acclimatization process
- Aeration
- Shrimp fry observation
- Shrimp fry stocking to the rearing pond
- Post-stocking shrimp fry monitoring
Conical tanks can be an effective tool for a safer shrimp fry stocking process. This is because the shrimp fry stocking method affects shrimp survival and farming process throughout a single cycle.
