Advantages of Using Earthen Ponds for Cultivating Macrobrachium rosenbergii Compared to Tank or HDPE Liner Ponds


Aquaculture has become a vital component of global food production, with increasing emphasis on sustainable practices. The Malaysian giant prawn, Macrobrachium rosenbergii, is a significant species in aquaculture due to its high market value and nutritional benefits. Various methods are employed to cultivate this species, including earthen ponds, tanks, and HDPE liner ponds. This article explores the advantages of using earthen ponds over tanks and HDPE liner ponds, focusing on the role of the soil microbiome in enhancing the health and growth of Macrobrachium rosenbergii.

Earthen Ponds: A Natural Advantage

Earthen ponds mimic natural ecosystems, providing a more balanced and conducive environment for the growth of Macrobrachium rosenbergii. The key advantages of using earthen ponds are rooted in the complex interactions between the soil, water, and the aquatic organisms.

1. Soil Microbiome and Nutrient Cycling

One of the primary benefits of earthen ponds is the presence of a rich soil microbiome. The microbiome comprises various bacteria, fungi, and other microorganisms that play a crucial role in nutrient cycling. These microorganisms break down organic matter, releasing essential nutrients such as nitrogen, phosphorus, and potassium into the water. This process creates a nutrient-rich environment that supports the growth and health of Macrobrachium rosenbergii.

A study by Avnimelech (1999) found that earthen pond systems significantly enhance the nutrient availability and microbial activity, which are crucial for the growth of aquaculture species.

2. Enhanced Water Quality

The interaction between soil and water in earthen ponds helps maintain optimal water quality. The soil acts as a natural filter, absorbing and breaking down waste products and excess nutrients. This process reduces the accumulation of harmful substances such as ammonia and nitrates, which can negatively impact prawn health in tanks and HDPE liner ponds. Additionally, the soil microbiome contributes to the biological control of pathogenic organisms, further enhancing water quality.

3. Natural Food Sources

Earthen ponds provide a habitat for a diverse range of natural food sources, including plankton, algae, and detritus. These natural food sources are readily available to the prawns, supplementing their diet and promoting better growth rates compared to artificial feeds used in tanks and HDPE liner ponds. The availability of natural food also reduces feed costs and improves feed conversion efficiency.

Research has shown that prawns cultivated in earthen ponds exhibit better growth performance and higher survival rates compared to those raised in tanks

4. Improved Prawn Health and Immunity

The complex and dynamic environment of earthen ponds supports the development of a robust immune system in Macrobrachium rosenbergii. The exposure to a variety of microorganisms and natural environmental stressors helps enhance the prawns' resilience to diseases and environmental fluctuations. In contrast, the relatively sterile conditions of tanks and HDPE liner ponds can lead to increased susceptibility to diseases and stress.

Comparative Analysis: Tanks and HDPE Liner Ponds

While tanks and HDPE liner ponds offer certain advantages such as ease of management and biosecurity control, they lack the natural benefits provided by earthen ponds.

1. Limited Microbial Diversity

Tanks and HDPE liner ponds do not support the same level of microbial diversity as earthen ponds. The absence of a rich soil microbiome means that nutrient cycling and natural waste breakdown processes are less efficient, potentially leading to water quality issues and increased reliance on artificial filtration systems.

2. Higher Management Costs

Maintaining optimal water quality and providing adequate nutrition in tanks and HDPE liner ponds often requires significant investment in aeration systems, water treatments, and artificial feeds. These management practices increase operational costs and can impact the sustainability of aquaculture operations.

3. Environmental and Health Challenges

The sterile and controlled environment of tanks and HDPE liner ponds can create conditions conducive to the rapid spread of diseases. The lack of natural microbial interactions and environmental stimuli may result in weaker immune systems in the prawns, making them more vulnerable to infections and stress.


The advantages of using earthen ponds for cultivating Macrobrachium rosenbergii are evident in the enhanced health and growth of the prawns. The natural soil microbiome, improved water quality, availability of natural food sources, and better immune system development contribute to more sustainable and cost-effective aquaculture practices. While tanks and HDPE liner ponds offer certain benefits, the holistic and balanced environment of earthen ponds provides a superior platform for the cultivation of healthy and resilient Macrobrachium rosenbergii. Embracing earthen pond systems can significantly contribute to the advancement of sustainable aquaculture and ensure the long-term success of aquaculture operations.
