Coastal vs inland RAS: how to choose
Quick answer
Coastal RAS sites make seawater intake simple and suit salmon and marine species, but land and permits are often harder. Inland RAS sites are usually cheaper and closer to consumers, but need a salt or brackish water plan for marine species.
Coastal (onshore) RAS
- Easy access to seawater for marine species
- Often higher land prices and stricter coastal permits
- Exposure to storms and sea-level risks
- Good for export-oriented farms near ports
Inland RAS
- Lower land cost and more site options
- Closer to city markets, fresher product
- Needs groundwater, brackish water or artificial salt for marine species
- Discharge of saline water must be planned carefully
How to decide
Compare total cost per kilo delivered to your buyer, not only land price. Include water treatment, salt, energy, transport and permit time in the comparison.
