Causes of Slow Shrimp Growth and Probiotic Pond Solutions

Slow shrimp growth in ponds is a nightmare for commercial farmers. When shrimp fail to reach harvest size on schedule, operational costs swell and income declines. This article scientifically reviews the main causes of slow shrimp growth in ponds and how Biosolution's probiotic solution, the Vaname Shrimp Pond Probiotic Formula, can be an effective answer to this problem.

Why Do Shrimp Grow Slowly in Ponds?

Suboptimal shrimp growth can be caused by several interrelated factors. Here are the main causes often encountered in the field:

Poor Water Quality

High ammonia and nitrite are toxic to shrimp. At ammonia concentrations >0.1 ppm, shrimp experience stress, decreased appetite, and stunted growth. In addition, fluctuations in temperature, pH, and dissolved oxygen also affect shrimp metabolism.

Pathogenic Bacterial Attacks

Vibrio spp. bacteria, especially Vibrio harveyi and Vibrio parahaemolyticus, can cause diseases such as vibriosis, leading to mortality and slow growth. High Vibrio populations (>10^3 CFU/mL) are a risk indicator.

Suboptimal Feed

Feed that does not meet nutritional requirements or contains hard-to-digest ingredients prevents shrimp from getting enough energy to grow. Feed conversion ratio (FCR) becomes high.

Environmental Stress

Overstocking, rough handling, or extreme weather changes stress shrimp and divert energy from growth to stress response.

Impact of Losses Due to Slow Shrimp Growth

Losses from slow shrimp growth are very real for commercial farmers. Here are some impacts:

• Extended harvest cycle: If harvest should be at 90 days, it can drag on to 120 days.
• Increased operational costs: Electricity, feed, and labor increase.
• Decreased survival rate (SR): Stressed shrimp are more prone to death.
• Low selling price: Shrimp size is not uniform and tends to be small.

Data shows that the SR of vaname shrimp in conventional ponds averages 60-70%, but with good management it can be increased to 80-85%.

Probiotic Solutions to Overcome Slow Shrimp Growth

Pond probiotics have been scientifically proven to improve water quality, suppress pathogens, and enhance shrimp growth. Biosolution's Vaname Shrimp Pond Probiotic Formula contains four superior bacterial strains that work synergistically:

• Bacillus subtilis: Anti-Vibrio and organic decomposer, capable of producing antibacterial compounds that suppress Vibrio populations by up to 40%.
• Bacillus licheniformis: Producer of extracellular enzymes such as protease, amylase, and lipase that help digest leftover feed and feces, thereby reducing organic load.
• Nitrosomonas sp.: Oxidizes ammonia to nitrite, keeping ammonia levels stable <0.1 ppm.
• Nitrobacter sp.: Oxidizes nitrite to safer nitrate.

This combination creates a healthy nitrogen cycle, reduces water exchange needs by up to 30%, and creates an optimal pond environment for shrimp growth.

Proper Application of Pond Probiotics

Probiotic application must be done regularly for maximum results. Here is a guide for using the Vaname Shrimp Pond Probiotic Formula:

• Dosage: 5 liters per hectare of pond.
• Frequency: Every 7-10 days.
• Time: Morning or evening when water temperature is not too hot.
• Method: Broadcast evenly directly into the pond.

Ensure probiotics are stored in a cool place away from direct sunlight. Before application, the pond should be in stable condition (pH 7.5-8.5, salinity 15-30 ppt).

Real Results of Probiotic Application

Field data shows that consistent probiotic application yields significant results:

• Vaname shrimp survival rate (SR) increases by 10-15%.
• Vibrio population drops by up to 40%.
• Ammonia stabilizes below 0.1 ppm.
• Water exchange is reduced by 30%, saving costs.

With higher SR and a healthier environment, shrimp grow faster and more uniformly. Farmers can harvest on time with desired sizes.

Conclusion

Slow shrimp growth in ponds is caused by poor water quality, pathogen attacks, and environmental stress. Probiotic solutions with Bacillus subtilis, Bacillus licheniformis, Nitrosomonas, and Nitrobacter can address this problem naturally and effectively. Biosolution's Vaname Shrimp Pond Probiotic Formula has been proven to increase SR by 10-15%, suppress Vibrio by 40%, and save water exchange by 30%. For optimal results, apply regularly every 7-10 days at a dose of 5 L/ha.
