The Effect of Probiotic Application on Water Quality and Litopenaeus Vannamei Shrimp Growth

Introduction

The aquaculture industry has been growing rapidly in recent years, with shrimp being one of the most popular and profitable species to cultivate. However, shrimp farming is often plagued by water quality issues, which can lead to reduced growth rates, increased mortality, and decreased profitability. One potential solution to these problems is the use of probiotics, which have been shown to improve water quality and promote healthy growth in various aquatic species. In this study, we investigated the effect of probiotic application on water quality and Litopenaeus vannamei shrimp growth.

Background

Probiotics are live microorganisms that, when administered in adequate amounts, confer a health benefit on the host. In the context of aquaculture, probiotics have been used to improve water quality, reduce the use of antibiotics, and promote healthy growth in various species. Probiotics can contribute positively to water quality by controlling the number of pathogenic bacteria and improving nitrification. By reducing levels of ammonia and harmful bacteria, the aquaculture environment becomes healthier and supports optimal growth.

Methodology

This study used an experimental method with four different treatments: the addition of probiotics with a dose of 0.1 g, 0.3 g, and 0.5 g, as well as one control treatment that did not use probiotics. Each treatment was repeated three times to produce more accurate data. Water quality parameters such as temperature, pH, number of bacteria, dissolved oxygen levels (DO), ammonia concentrations, salinity, alkalinity, and the presence of vibrio were measured every day. While the weight and survival rate of shrimp were measured at the end of the study.

Results

The results of this study showed that the probiotic dose of 0.3 g and 0.5 g was able to increase the survival rate of shrimp by 82.66% and 70.66%, respectively. The weight of shrimp also increased, which was 8.89 g and 7.71 g, respectively. In addition, this probiotic application has succeeded in reducing the number of vibrio bacteria by 510 cells/ml and ammonia levels by 0.015 mg/l.

Discussion

The use of probiotics in shrimp cultivation is an increasingly popular approach among farmers. Probiotics can contribute positively in improving water quality by controlling the number of pathogenic bacteria and improving nitrification. By reducing levels of ammonia and harmful bacteria, the aquaculture environment becomes healthier and supports optimal growth. From the results of this study, it appears that the probiotic dose is higher, which is 0.3 g and 0.5 g, gives a better effect than the lowest dose. This shows the importance of selecting the right dose in the use of probiotics in order to provide maximum results.

Conclusion

Overall, this study concluded that the application of probiotics not only had a positive effect on water quality but also contributed greatly in increasing the growth of Litopenaeus vannamei shrimp. Therefore, this technology adoption can be a strategic step for shrimp farmers in increasing productivity and sustainability of their cultivation business. The use of probiotics can help reduce the use of antibiotics, which are often needed to fight diseases in fish and shrimp farming. By relying on probiotics, cultivation can be more sustainable and environmentally friendly, maintaining the balance of the ecosystem in the pond.

Recommendations

Based on the results of this study, we recommend the use of probiotics in shrimp cultivation as a potential solution to improve water quality and promote healthy growth. The optimal dose of probiotics should be determined based on the specific needs of the farm and the species being cultivated. Additionally, further research is needed to investigate the long-term effects of probiotic application on water quality and shrimp growth.

Limitations

This study had several limitations, including the small sample size and the limited number of treatments. Additionally, the study only investigated the effect of probiotics on water quality and shrimp growth, and did not examine other potential benefits of probiotic application, such as improved disease resistance.

Future Research Directions

Future research should focus on investigating the long-term effects of probiotic application on water quality and shrimp growth. Additionally, further research is needed to investigate the optimal dose of probiotics for different species and farming systems. The use of probiotics in aquaculture has the potential to improve water quality, reduce the use of antibiotics, and promote healthy growth in various species. Therefore, further research is needed to fully understand the benefits and limitations of probiotic application in aquaculture.
