Shrimp jumping out of the water may look like a sign of vitality, but in fact, it is a serious warning signal in aquaculture. When shrimp frequently leap to the water surface, it means their living environment is under stress or imbalance. If farmers ignore this behavior, it can lead to heavy losses—even complete crop failure.
This article explains the main causes of shrimp jumping, immediate treatment measures, and long-term prevention strategies to help shrimp farmers maintain stable pond environments and achieve higher productivity.
Why Do Shrimp Jump Out of the Water?
1. Low Dissolved Oxygen (DO)
When dissolved oxygen drops below safe levels (typically <4 mg/L), shrimp suffer from suffocation and are forced to swim upward for oxygen. This shortage often happens at night or early morning because algae and microorganisms consume oxygen through respiration, while photosynthesis is inactive.
Contributing factors include:
- High stocking density
- Insufficient aeration equipment
2. Stress After Rainfall
Rainwater, especially early-season rains, can wash alum (containing aluminum and iron ions) into the pond. This reduces pH sharply and causes acidic, polluted conditions. Alum particles may clog shrimp gills, forcing them to leap out in search of safer water.
3. Organic Matter Accumulation
Excess feed, shrimp waste, and organic debris at the pond bottom generate toxic gases such as hydrogen sulfide (H₂S) and ammonia (NH₃). When concentrations increase:
- Shrimp show reduced appetite
- Weak swimming and frequent jumping
- Floating at the surface
4. Toxic Water Quality Parameters
High levels of ammonia (NH₃/NH₄) and nitrite (NO₂) severely damage shrimp gills and hepatopancreas, leading to poisoning and oxygen deficiency. Sudden salinity changes and excess H₂S also contribute to abnormal jumping.
Emergency Solutions When Shrimp Jump Out of Water
Increase Dissolved Oxygen
- Run Paddle wheel aerators and Rootsblower aeration systems continuously
- Apply oxygen-releasing agents (granular oxygen or liquid oxygen) in critical situations
- Temporarily reduce feed input to minimize oxygen demand
Rainfall Shock Management
- Stop feeding immediately
- Reduce heavy aeration to avoid stirring alum deposits
- Apply lime or dolomite to increase pH and neutralize toxic ions
- Monitor pH frequently until it stabilizes
Organic Pollution & Toxic Gas Management
- Apply probiotics to decompose organic matter
- Use zeolite or mineral powder to absorb toxic gases
- If possible, perform partial water exchange
- Increase aeration to improve circulation
Stress Relief
- Apply Vitamin C, glucose, or anti-stress additives to boost shrimp resilience
- Closely observe shrimp behavior, feeding activity, and water color after treatment
Long-Term Prevention Strategies for Shrimp Farmers
1. Regular Water Quality Monitoring
Check and maintain:
- Dissolved oxygen
- pH and alkalinity
- Ammonia, nitrite, and H₂S levels
2. Pond Bottom Management
- Apply probiotics regularly to keep pond bottom clean
- Decompose organic waste efficiently
3. Balanced Feeding and Stocking Density
- Avoid overstocking to reduce competition and oxygen demand
- Provide adequate nutrition with minerals and vitamins to enhance shrimp immunity
4. Rainwater Management
- Build strong pond embankments
- Use plastic film or drainage systems to reduce runoff contamination
- Test pH immediately after rain and apply corrective treatments
Conclusion
Shrimp jumping out of water is not a sign of health, but a warning of environmental stress such as low oxygen, toxic gases, or water quality imbalance. By taking quick action—boosting aeration, correcting pH, applying probiotics, and reducing stress—farmers can prevent heavy losses.
In the long term, consistent water quality management, bottom maintenance, density control, and rainwater prevention are key to stable pond environments and successful shrimp farming.
Maintaining these practices will help shrimp farmers ensure healthier stock, higher survival rates, and better profits throughout the farming season.
👉 To improve pond oxygenation and reduce risks of shrimp stress, farmers can use professional aeration equipment such as Paddle Wheel Aerators, Impeller Aerators, Air Jet Aerators, Wave Maker Aerators, and Roots Blowers. Choosing the right aerator ensures a stable and healthy pond environment for higher shrimp production.
