Tips to Minimize the Environmental Impact of Shrimp Farming

Shrimp farming is a crucial sector in the global economy, but unsustainable practices can have serious environmental consequences. Therefore, farmers need to pay closer attention to the environmental impact of shrimp farming.

In efforts to sustain this industry while protecting ecosystems, smart and sustainable steps are necessary. Here are some tips to minimize the environmental impact of shrimp farming that you can implement:

Tips to Minimize the Environmental Impact of Shrimp Farming

1. Selecting the Right Location

Choose shrimp farming locations that are ecologically non-sensitive. Avoid areas vulnerable to coastal erosion, intact mangrove forests, or regions with high biodiversity.

Selecting the right location can reduce negative environmental impacts and promote sustainable shrimp farming practices.

2. Efficient Water Management

Effective water management is crucial for vannamei shrimp farming. This helps avoid pollution and reduces excessive water use, thereby supporting environmental sustainability.

3. Sustainable Feed Choices

Choosing sustainable feed is crucial to minimize environmental impacts of shrimp farming. The composition of shrimp feed determines the nutrients absorbed by shrimp for their growth. Ensure that the feed composition is nutritionally adequate while remaining eco-friendly.

4. Water Quality Monitoring

Regularly monitor water quality around the farming area. Ensure parameters like dissolved oxygen levels, salinity, and water clarity remain optimal to support shrimp growth and prevent environmental pollution.

5. Use of Environmentally Friendly Technologies

Employ the latest environmentally friendly technologies in shrimp farming systems. For example, implement drilling technologies to minimize damage to underwater ecosystems during infrastructure development.

6. Environmental Stewardship Practices

Shrimp farming practices should be responsible and considerate of surrounding environmental conditions, particularly in waste management. Many farmers still lack proper waste management facilities due to land and capital limitations.

Environmental stewardship involving good waste management practices should be implemented throughout the farming cycle, from pond cleaning to managing aquaculture wastewater.

7. Collaboration with Stakeholders

The final tip to minimize the environmental impact of shrimp farming is collaboration among involved parties. This includes tighter and more sustainable operational standards and regulations.

Enhancing Shrimp Farming: The Role of Synbiotics in Boosting Health, Growth, and Disease Resistance in Litopenaeus vannamei

The Pacific white shrimp (Litopenaeus vannamei) is a dominant force in the aquaculture industry, accounting for a substantial 52.9% of global production. Nonetheless, shrimp farms face significant challenges due to diseases caused by various microorganisms. Given the current disease threats, it is crucial to prioritize and implement effective disease management strategies in order to maintain the long-term viability and financial success of shrimp farming operations.

A highly intriguing solution that has captured significant attention is the incorporation of synbiotics as feed additives. Combining probiotics and prebiotics into synbiotics provides a wide array of advantages that go beyond what probiotics or prebiotics can offer individually. Prebiotics are essential for optimizing the success of these treatments as they support the survival and colonization of probiotics in the shrimp’s gut, thereby maximizing their overall effectiveness. This symbiotic connection contributes to the maintenance of a balanced and thriving intestinal ecosystem, which plays a crucial role in promoting shrimp’s overall health.

Extensive research has shown that certain bacteria can have a positive effect on shrimp growth, as well as help prevent the spread of harmful microorganisms and maintain a stable intestinal environment. Both controlled experiments and real-life situations consistently observe these beneficial outcomes. Prebiotics play a crucial role in maintaining a healthy gut microbiome in shrimp, promoting the growth of beneficial bacteria, and suppressing harmful bacteria. This balance is critical for the shrimp’s overall health.

Integrating synbiotics into shrimp diets can result in better growth performance, improved feed utilization, enhanced disease resistance, increased nutrient digestibility, and a boosted immune system. Research has indicated that the inclusion of synbiotics in dietary supplements can have a positive impact on the growth, intestinal health, and immune response of shrimp. These discoveries indicate that synbiotics could greatly transform the shrimp farming industry by enhancing overall health and disease resistance, making them a valuable asset to contemporary aquaculture methods.

Understanding Shrimp Nursery and Its Benefits in Aquaculture

Shrimp nursery is one of the methods used to assist in the growth of shrimp larvae into juveniles (called “benur”) ready for aquaculture. This method offers several benefits, especially in reducing stress levels among benur when they are transferred to cultivation ponds.

Nursery plays a crucial role in helping shrimp adapt to pond environments. Vannamei shrimp, in particular, naturally inhabit brackish waters. Moreover, undenurtured shrimp larvae often struggle to adapt and have higher mortality rates.

For those interested in trying vannamei shrimp nursery, here are the steps:

What is Shrimp Nursery?

Shrimp nursery involves the process of growing shrimp larvae into post larvae. The aim is to increase the survival rate of post larvae released into ponds. Additionally, vannamei shrimp nursery helps farmers obtain uniformly sized and high-quality shrimp.

Successful Shrimp Nursery Techniques

1. Prepare the Nursery Environment and Fill with Water

The first step involves preparing the nursery environment and filling it with water. An ideal nursery pond is rectangular and made of concrete. Ensure rounded corners to prevent debris buildup and facilitate water circulation. Before use, the pond should be cleaned, dried, and equipped with aeration systems and blowers for oxygenation.

For water filling, seawater is recommended. Ensure the pond is dry and the installation system is in place before filling. Water is added through an inlet pipe equipped with filters to remove any remaining impurities. Once filled with seawater, add sodium or EDTA (Ethylene Diamine Tetraacetic Acid) at 10 ppm for larval maintenance.

2. Release the Post Larvae

During the nursery phase, the shrimp larvae placed in the pond are nauplii. Before placement, nauplii need to acclimate for 15 minutes to adjust to the pond water temperature.

3. Feeding

At this stage, it’s crucial to pay attention to the type, dosage, and frequency of feeding. Larvae can be fed natural or artificial feeds, but nauplii should preferably be fed natural feeds as they still have their yolk sacs as food reserves. Artificial feeds are only necessary when larvae develop into zoea within 40 hours, requiring fine particles that larvae can consume. Phytoplankton should only be provided up to the mysis stage, then replaced with artemia at the post larvae stage. Feeding doses should be adjusted according to larval stages to maintain health and growth.

4. Proper Water Management

At this stage, regular water exchange in the pond is crucial. Without exchange, leftover feeds and feces can threaten larval health. Water exchange aims to maintain stable water parameters such as temperature, salinity, and pH, preventing stress in larvae due to sudden changes in water conditions.

5. Harvesting Post Larvae Carefully

Harvesting post larvae is done after passing stress tests, salinity tests, and being declared free from diseases and luminescent bacteria. The harvesting process begins by draining 40% of the pond water, installing nets, and opening water channels. Post larvae are caught using harvesting nets, then transferred to buckets filled with water at 28 degrees Celsius. After this process, post larvae are ready for cultivation in ponds by the farmers.
