Recirculating Aquaculture Systems (RAS) offer a modern approach to fish farming by recycling water and controlling the environment. This method reduces water use and allows for year-round production. However, setting up a RAS facility requires a significant investment. Understanding the costs involved in Indian Rupees (INR) helps potential farmers plan better and make informed decisions.

What Is Included in RAS Aquaculture Setup?

A RAS setup involves several components working together to maintain water quality and fish health. The main parts include:

• Fish tanks: These hold the fish and come in various sizes and materials.

• Water treatment units: Filters, biofilters, and UV sterilizers clean and recycle water.

• Pumps and plumbing: Circulate water through the system.

• Aeration systems: Provide oxygen to fish.

• Monitoring equipment: Sensors and control panels track water parameters like temperature, pH, and oxygen levels.

• Backup power: Generators or batteries ensure continuous operation during power failures.

  
  

Each component adds to the overall cost, and the scale of the farm influences the size and number of these units.

Breakdown of RAS Setup Costs in INR

The cost of setting up a RAS aquaculture system varies widely depending on the farm size, technology level, and location. Here is a rough estimate of expenses for a small to medium-scale setup in India:

| Component | Estimated Cost (INR) |

|------------------------|-------------------------------|

| Fish tanks | 2,00,000 to 5,00,000 |

| Water treatment units | 3,00,000 to 7,00,000 |

| Pumps and plumbing | 1,00,000 to 3,00,000 |

| Aeration system | 50,000 to 1,50,000 |

| Monitoring equipment | 1,00,000 to 2,50,000 |

| Backup power system | 1,50,000 to 3,00,000 |

| Construction and setup | 2,00,000 to 5,00,000 |

| Total | 11,00,000 to 27,00,000 |

These figures are approximate and can vary based on supplier, technology, and customization.

Factors Affecting the Cost

Several factors influence the final cost of a RAS aquaculture setup:

• Farm size: Larger farms need more tanks and equipment, increasing costs.

• Technology level: Advanced automation and monitoring systems cost more but improve efficiency.

• Location: Costs for construction, labor, and materials differ across regions in India.

• Species farmed: Some fish require specific water conditions and equipment.

• Quality of materials: Durable, high-quality materials increase upfront costs but reduce maintenance.

  
  

Examples of Cost Variation

For example, a small RAS setup for tilapia farming with a capacity of 5 tons per cycle might cost around ₹12 lakh. This includes basic tanks, filters, and manual monitoring.

On the other hand, a medium-scale system for high-value species like shrimp or trout with automated controls and backup power could reach ₹25 lakh or more.

Operational Costs to Consider

Setting up the system is just the beginning. Operational costs also impact the total investment:

• Electricity for pumps, aerators, and heating or cooling

• Feed and fish stock

• Labor for daily maintenance and monitoring

• Water quality testing supplies

• Repairs and replacement parts

  
  

These costs vary but can add 20-30% of the initial setup cost annually.

Ways to Manage and Reduce Costs

Farmers can take steps to manage costs effectively:

• Start with a smaller system and expand gradually.

• Choose locally available materials and equipment.

• Use energy-efficient pumps and aerators.

• Train staff to maintain equipment properly.

• Explore government subsidies or loans for aquaculture projects.

  
  

Summary

Setting up a RAS aquaculture system in India requires an investment ranging from ₹11 lakh to ₹27 lakh for small to medium farms. The cost depends on farm size, technology, location, and species. Operational expenses add to the total investment over time. Careful planning and cost management can make RAS a profitable and sustainable fish farming method.
