Wave Generation in Fish Tank Farming: An Economic Perspective

Explore how a single PMBazaar wave-generated FRP tank can serve as the foundation for a successful fish farming business. Designed for efficient space utilisation and streamlined production, this one-tank model enables farmers to start with clarity, manage costs effectively, and generate income within a 4- to 5-month cycle.

Start Small. Produce Big. Grow with Confidence.

PM Bazaar’s one-tank model is designed for farmers seeking a practical entry point into modern aquaculture while maintaining profitability. With a well-planned single tank, farmers can aim for a production capacity of up to 2,000 kg. This approach follows a defined cycle, features a predictable cost structure, and promotes a measurable income model.

Tank Configuration

This model features a round tank made of fibreglass-reinforced plastic (FRP). The tank measures 15 feet in diameter and 4.5 feet in height and has a total capacity of 22,500 liters of water. This setup includes a 1 HP wave maker with pipe fittings and an automatic timer controller that operates the wave maker for one hour and then shuts it off. Additionally, there’s a waterfall feature to increase water movement and maintain oxygen levels, as well as accessories designed to ensure optimal conditions for fish farming.

Tank Type: FRP Cylinder Tank.
Tank Size: 15 feet diameter x 4.5 feet height.
Water Volume: 22,500 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. 1,20,000 for the FRP cylinder tank and Rs. 30,000 for the wave maker system with pipe fitting, timer controller, and accessories. The total fixed investment for one tank setup is Rs. 1,50,000.

Running Cost Per Cycle

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

FRP Tank: Rs. 1,20,000
Wave Maker System: Rs. 30,000
Total Fixed Cost: Rs. 1,50,000
Running Cost Per Cycle: Rs. 1,20,000

Production Assumptions

The one-tank economics model helps farmers make more accurate estimates of production and income. It is based on practical production estimates and assumes the following: 2,000 fish seeds per tank, a seed size of 4 to 5 inches, an average 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
Note: All fish species can be raised in this tank.

Revenue Potential Per Cycle

In a single cycle, a one-tank model produces a total of 2,000 kg of fish, which, at a selling price of ₹100 per kg, generates total sales revenue of ₹200,000. This clearly illustrates how fish production creates revenue for farmers.

Sale Quantity: 2,000 kg.
Sale Price: Rs. 100 per kg.
Gross Sale Value: Rs. 2,00,000

Net Profit Snapshot

After considering one cycle’s running expenses of Rs. 1,20,000, the model indicates a net profit of Rs. 80,000 per cycle. The presentation also projects 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 one-year ROI section of the presentation explains that the first cycle includes both the complete setup investment and operating costs. In subsequent cycles, expenses decrease because the fixed tank purchase is no longer necessary. In the first cycle, the total expenses amount to Rs. 2,70,000, with an investment recovery of Rs. 80,000. By the second cycle, the total recovery increases to Rs. 1,60,000.

First Cycle

The first cycle comprises fixed costs of Rs. 1,50,000 and running costs of Rs. 1,20,000, totalling expenses of Rs. 2,70,000. The ROI section indicates an investment recovery of Rs. 80,000 during this stage.

Second Cycle

In the second cycle, the fixed tank purchase cost becomes zero, while the running cost remains Rs. 1,20,000. The presentation indicates 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.
