One Tank Fish Farming Economics

Discover how a single PMBazaar wave-generated FRP tank can become the foundation of a profitable fish farming business. Built for efficient space use and structured production, this one-tank model is designed to help farmers begin with clarity, control costs, and generate income in a 4 to 5-month cycle.

Start Small. Produce Big. Grow with Confidence.

PM Bazaar’s one-tank model is built for farmers who want a practical entry point into modern aquaculture without losing sight of profitability. With one well-planned tank, farmers can target up to 2,000 kg production capacity while following a defined cycle, predictable cost structure, and measurable income model.

Tank Configuration

This model is based on an FRP cylinder tank measuring 15 diameter x 4.5 height with a water volume of 20,000 liters. The setup also includes a 0.5 HP wave maker with pipe fitting, an automatic timer controller, and accessories to support water movement and better fish growing conditions.

  • Tank Type: FRP Cylinder Tank.

  • Tank Size: 15 diameter x 4.5 height.

  • Water Volume: 20,000 liters.

  • Production Capacity: Up to 2,000 kg

Investment Breakdown

The one-tank model is designed with a clear two-part cost structure: fixed setup cost and cycle-based operating cost. This makes it easier for farmers to understand where the investment goes and how the business can be managed across each crop cycle.

Fixed Setup Cost

The fixed cost includes Rs. 80,000 for the FRP cylinder tank and Rs. 20,000 for the wave maker system with pipe fitting, timer controller, and accessories. The total fixed investment for one tank setup is Rs. 1,00,000.

Running Cost Per Cycle

For one crop cycle, the model includes fish seed, feed, and electricity plus maintenance expenses. The presentation shows a total running cost of Rs. 1,20,000 for a 4 to 5-month cycle.

  • FRP Tank: Rs. 80,000

  • Wave Maker System: Rs. 20,000

  • Total Fixed Cost: Rs. 1,00,000

  • Running Cost Per Cycle: Rs. 1,20,000

Production Assumptions

The one-tank economics model is built on practical production assumptions that help farmers estimate output and income more accurately. It assumes 2,000 fish units, a seed size of 4 to 5 inches, an average body weight of 1 kg per fish, and a rearing period of 4 to 5 months.

  • Fish quantity: 2,000

  • Seed size: 4 to 5 inches

  • Fish type reference: Hybrid Pangasius Rupchanda

  • Average body weight: 1 kg per fish

  • Crop cycle: 4 to 5 months

 

Revenue Potential Per Cycle

At a total sale quantity of 2,000 kg and a farmer’s sale price of Rs. 100 per kg, the one-tank model delivers a total sale value of Rs. 2,00,000 per cycle. This provides a simple and transparent view of how production converts into revenue at the farmer level.

  • Sale Quantity: 2,000 kg.

  • Sale Price: Rs. 100 per kg.

  • Gross Sale Value: Rs. 2,00,000

Net Profit Snapshot

After accounting for one cycle running expenses of Rs. 1,20,000, the model shows a net profit of Rs. 80,000 per cycle. The presentation also estimates the monthly income at Rs. 20,000 based on this cycle structure.

  • Net Expenses: Rs. 1,20,000

  • Net Profit Per Cycle: Rs. 80,000

  • Estimated Monthly Income: Rs. 20,000

Investment Recovery Outlook

The presentation’s one-year ROI section shows that the first cycle includes the full setup investment and operating cost, while later cycles benefit from the fact that the fixed tank purchase does not repeat. In the first cycle, total expenses are shown as Rs. 2,20,000, with investment recovery of Rs. 80,000, and by the second cycle the combined recovery reaches Rs. 1,60,000.

First Cycle

The first cycle includes Rs. 1,00,000 fixed cost and Rs. 1,20,000 running cost, resulting in total expenses of Rs. 2,20,000. The ROI section shows an investment recovery of Rs. 80,000 during this stage.

Second Cycle

In the second cycle, the fixed tank purchase cost becomes nil, while the running cost remains Rs. 1,20,000. The presentation states that the combined recovery after the first and second cycles reaches Rs. 1,60,000.

Why the One Tank Model Works

The strength of this model lies in its simplicity, space efficiency, and structured economics. It gives farmers a practical way to start with one manageable unit, understand their numbers clearly, and scale with greater confidence once the first cycle proves successful.

  • Low-entry model for first-time fish farmers.

  • Suitable for limited space and controlled production.

  • Defined cycle-based planning improves decision-making.

  • Easy to scale from one tank to multiple tanks.
