How It Works

Pond Structure Diagram

Pond Excavation Diagram

Pond Structure

• Embankment: Raised earthen wall around the pond

• Bokchor: Flat step inside the pond after embankment slope

• Pond: Water body for fish farming

• Chandina: Width of the flat top surface of embankment

Calculation Method

• Area = Average Length × Average Width

• Frustum Volume = (Depth ÷ 3) × (Top Area + Bottom Area + √(Top × Bottom))

• 1 Satak = 435.6 sq ft

Earth Balance Information

• Total excavation = Pond volume + Bokchor volume

• Embankment needs 25% more soil due to compaction (loose soil compacts when packed)

About Pond Excavation

Pond excavation for fish farming is a crucial step. Without proper measurement and planning, pond excavation can lead to extra costs and problems. This calculator will help you make accurate calculations.

Parts of a Pond

  • Embankment (Par): The raised earthen wall around the pond that holds water
  • Bokchor (Inner Ledge): A flat step inside the pond after the embankment slope
  • Chandina (Top Width): The width of the flat top surface of the embankment

Ideal Pond Dimensions

  • Depth: 6-10 feet (2-3 meters)
  • Embankment width: 25-35 feet
  • Bokchor: 2-4 feet
  • Embankment height: 8-12 feet

Tips: Consult a local fisheries expert before determining pond size. Consider soil type and water availability.

🐟 Benefits of Fish Farming

💰

Additional Income

Extra income from fish farming alongside agriculture

🌾

Land Utilization

Productive use of low-lying or unused land

🥗

Nutritious Food

Fresh and nutritious fish for the family

💧

Water Conservation

Pond water can also be used for irrigation

❓ Frequently Asked Questions

What is a pond excavation calculator?
A pond excavation calculator is a tool that calculates embankment volume, bokchor area, and pond excavation volume from land measurements. It helps fish farmers estimate costs accurately.
What is Bokchor and why is it needed?
Bokchor is a flat step inside the pond after the embankment slope. It prevents erosion, creates shallow areas for fish, and makes net hauling easier. Usually 2-4 feet wide.
What is the ideal pond depth?
The ideal pond depth for fish farming is 6-10 feet (2-3 meters). This ensures adequate water volume for fish growth, stable temperature, and proper oxygen circulation.
Where is the embankment soil used?
The embankment is built using soil from pond excavation. The excavation volume should roughly equal the embankment volume. Excess soil needs to be removed or used to raise the embankment.
