🐟 Snapshot
Salmon fish farming in India is emerging as a high-value aquaculture business, driven by rising demand for protein-rich seafood and premium exports. While traditionally suited to colder climates, salmon farming is now possible in India using modern technologies like Recirculating Aquaculture Systems (RAS). From choosing the right location and fish species to setting up the farm, managing temperature, and ensuring high yield, this guide walks you through every step. With proper planning, investment, and government support, a salmon fish farm can deliver significant profits in India’s growing aquaculture sector.
Salmon fish farming, once a concept mostly confined to cold countries, is now gaining traction in India due to increasing demand for protein-rich diets and growing seafood exports. A salmon fish farm can be a profitable venture if done with proper planning, technology, and environmental care. In this guide, we simplify everything you need to know about salmon farming in India—from setup to sale.
What is Salmon Fish Farming?
Salmon fish farming is a type of aquaculture where salmon are raised under controlled conditions for commercial sale. The two most common types farmed globally are:
- Atlantic Salmon (Salmo salar)
- Pacific Salmon (Oncorhynchus species)
In India, research is ongoing to adapt salmon farming to inland or controlled environments due to temperature challenges.
Note: Salmon require cold, oxygen-rich water (optimal: 8–14°C), which limits farming to specific Indian regions.
Expert Tip: Try Recirculating Aquaculture Systems (RAS) or cold-water aquaculture tanks to simulate native habitat conditions.
Key Features
| Feature | Details |
|---|---|
| Growth Period | 18 to 24 months |
| Optimal Temperature | 8–14°C |
| pH Level | 6.5 to 8 |
| Water Type | Cold, freshwater/saltwater |
| Feeding | High-protein formulated feed |
One-Line Tip: Focus on temperature control and oxygenation for high yield in salmon fish farming.
Is Salmon Fish Farming Possible in India?
Yes, but it comes with challenges:
Suitable Locations:
- Himachal Pradesh
- Uttarakhand
- Jammu & Kashmir
- Sikkim
- North-Eastern Hill Stations
Current Scenario:
- India imports a significant amount of salmon.
- Domestic salmon farming is in the early stages but has high potential due to rising demand.
Note-Worthy: ICAR and NFDB are running trials for salmon aquaculture in controlled systems.
Types of Salmon Species for Farming
India is currently experimenting with various salmon species to suit its diverse climates. Here are the most prominent types:
| Species Name | Origin | Suitability in India | Growth Rate | Notes |
| Atlantic Salmon | North Atlantic | Moderate (needs RAS) | Medium | Most commonly farmed globally |
| Chinook Salmon | Pacific Ocean | Low | High | Sensitive to temperature |
| Coho Salmon | Pacific Ocean | Moderate | Medium | Potential for NE hill states |
How to Start a Salmon Fish Farm in India (Step-by-Step Guide)
Step 1: Market Research & Business Planning

| Recirculating Aquaculture | Closed systems (recommended) |
Expert Guide: Choose RAS for higher productivity and year-round farming.
Step 3: Infrastructure Setup
- Land & water source (5-10 acres for medium farm)
- RAS tanks/cages
- Aerators, filters, chillers
- Power backup & shed
One-Line Tip: Ensure a 24/7 power supply to maintain stable temperature and oxygen levels.
Step 4: Seed & Feed Management

- Use high-protein feeds (40-50% protein)
- Feed 2–3 times daily based on age & weight
Step 5: Health & Disease Control
- Regular water testing (pH, DO, temperature)
- Quarantine new stock
- Use probiotics & natural disease preventives
Step 6: Harvesting & Selling
- Salmon matures in ~18-24 months
- Harvest using nets or tank draining
- Pack using cold chain logistics
Estimated Setup Cost Table

| Land Lease (per acre) | 1,00,000–2,00,000/year |
| RAS Setup (50,000 L tank) | 5–10 lakh |
| Fingerlings (per 1000) | 40,000–50,000 |
| Feed (per tonne) | 60,000–80,000 |
| Labour & Maintenance | 1–2 lakh/year |
| Total Setup Cost (approx.) | ₹10’20 lakh |
Water Quality Parameters for Salmon Farming
Maintaining optimal water quality is crucial for salmon health and growth.
| Parameter | Ideal Range |
| Temperature | 8–14°C |
| pH Level | 6.5 to 8.0 |
| Dissolved Oxygen | >7 mg/L |
| Ammonia (NH3) | <0.05 mg/L |
| Salinity (if used) | 15–30 ppt (for saltwater) |
Salmon Fish Lifecycle in Captivity
Understanding the salmon lifecycle helps optimise feeding, tank environment, and harvesting.
Lifecycle Stages
- Eggs: Incubated in trays at ~10°C.
- Alevin: Hatches from egg, absorbs yolk sac.
- Fry: Starts feeding independently.
- Fingerling: Juvenile stage, ready for grow-out.
- Smolt: Undergoes adaptation to saltwater.
- Adult: Ready for harvest in 18–24 months.
| Stage | Duration | Special Care |
| Egg-Alevin | 2–4 weeks | Maintain stable cold temperature |
| Fry | 1–2 months | Start feeding; control ammonia levels |
| Smolt | ~6 months | Gradual salinity adjustment if needed |
RAS Technology Explained
Recirculating Aquaculture Systems (RAS) allow salmon to be raised in controlled tanks with minimal water usage.
Components of RAS:
- Mechanical Filters: Remove solid waste.
- Biofilters: Convert ammonia into harmless nitrates.
- UV Sterilisers: Kill pathogens.
- Oxygen Injectors: Maintain dissolved oxygen levels.
- Temperature Control Units: Maintain optimal 8–14°C.
| Pros | Cons |
| Year-round farming | High initial setup cost |
| Controlled environment | Requires technical know-how |
| Less water consumption | Power-dependent |
One-Line Tip: RAS is the most viable system for salmon fish farms in warmer parts of India.
Feeding Schedule & Nutritional Needs
Feeding plays a crucial role in fish growth and profit.
Feed Types:
- Starter Feed (0–1 month): 50% protein
- Grower Feed (1–12 months): 45% protein
- Finisher Feed (12–24 months): 40% protein
| Age | Feed Type | Frequency |
| 0–1 month | Powder feed | 4 times/day |
| 1–6 months | Pellet (small) | 3 times/day |
| 6–24 months | Pellet (large) | 2 times/day |
Harvesting Methods & Post-Harvest Handling
Proper harvesting and cold chain maintenance determine fish quality and shelf-life.
Methods:
- Netting the fish from tanks or cages
- Gradual water lowering method
- Icing and immediate chilling (0°C)
| Step | Best Practice |
| Harvesting Time | Early morning |
| Packaging | Vacuum-packed, on ice |
| Transport | Refrigerated vans (cold chain) |
One-Line Tip: Reduce stress during harvesting to maintain meat quality.
