Rohu Fish Farming: Complete Guide on Cost, Profit, Health Benefits, and Marketing
Discover the complete guide to Rohu fish farming including farming techniques, cost, profit, health benefits, nutrition, recipes, marketing strategies, and FAQs.
Introduction
Rohu (Labeo rohita) is one of the most popular freshwater fish species in South Asia, especially in India, Bangladesh, Nepal, and Pakistan. A member of the carp family (Cyprinidae), Rohu is an essential part of composite fish farming systems along with Catla and Mrigal.
This fish is not only loved for its taste but also for its nutritional richness and market value. In India alone, Rohu accounts for nearly 35% of freshwater fish consumption. Due to its adaptability, fast growth rate, and high consumer demand, Rohu fish farming has become a profitable business for both small-scale farmers and commercial aquaculture entrepreneurs.
In this post, we will explore farming conditions, cost & investment, profit potential, health benefits, risks, nutritional value, medical use, recipes, marketing strategies, and FAQs about Rohu fish farming.
Farming Conditions for Rohu
Rohu thrives in tropical and subtropical climates. To achieve maximum growth and profit, farmers must maintain the following conditions:
Water Temperature: 25–32°C is ideal for Rohu. Below 20°C, growth slows significantly.
Water Type: Freshwater ponds, rivers, reservoirs, lakes, and tanks.
pH Level: 7–8 (slightly alkaline water is best).
Dissolved Oxygen: Minimum 5 mg/L.
Stocking Density: 4000–5000 fingerlings per acre.
Composite Farming: Rohu is best farmed with Catla (surface feeder) and Mrigal (bottom feeder) since Rohu feeds in the middle zone of water. This ensures efficient use of pond resources.
Cost & Investment
1. Fingerlings (Seeds)
Rohu fingerlings cost between ₹1–2 each (~$0.01–0.02).
For 1 acre pond, 4000–5000 fingerlings are required.
Total seed cost ≈ ₹8,000 – ₹10,000 ($100–120).
2. Feed
Feed includes rice bran, oil cakes, pellets, and natural pond productivity (plankton).
Feed costs account for 60–65% of total expenses.
Per acre annual feed cost ≈ ₹2–2.5 lakh ($2,400–3,000).
3. Pond Construction & Preparation
Initial pond construction costs: ₹50,000 – ₹70,000 ($600–850).
Regular liming, fertilization, and aeration included.
4. Maintenance & Labor
Disease prevention, water management, netting, and labor ≈ ₹40,000 – ₹60,000 ($500–750).
Total Investment per Acre = ₹3.5 – 4 lakh ($4,200 – 4,800).
Market Demand & Profit
Rohu is a staple diet in India, Bangladesh, and Nepal, making it a high-demand species.
Export markets exist in Gulf countries, Southeast Asia, and Europe.
Retail Price in India: ₹150–200 per kg ($1.8 – 2.5).
Yield per acre: 8–10 tons annually.
Revenue per acre: ₹14–20 lakh ($17,000 – 24,000).
Net Profit per acre: ₹8–12 lakh ($9,600 – 14,400).
Profit Margin = 40–50%.
