Raising Coho Salmon in Land-Based Systems

Coho salmon, one of the most prized Pacific salmon, is increasingly farmed in cold, land-based recirculating systems that bring salmon aquaculture inland. It rewards the grower with rich, red, premium fillets, but like all salmonids it demands cold, pristine, highly oxygenated water and serious life-support, making it a project for experienced cold-water growers.

Is it right for you?

Coho suit an experienced grower with a cold, well-engineered recirculating system who wants a premium salmon fillet. The water-quality and cooling demands rule them out for beginners.

System & Space

A large cold recirculating system with reliable chilling, oxygenation and biofiltration is required; coho need space and consistently pristine cold water to grow out.

Water & Temperature

They are cold-water fish needing consistently cold, highly oxygenated, clean water; lapses in temperature or oxygen quickly stress them.

Stocking & Feeding

Stock size-graded smolts and feed a high-protein salmonid diet; grade regularly. Filtration and aeration must stay well ahead of the heavy feeding load.

Health & Care

Cold, oxygen-rich, clean water prevents most disease; biosecurity, reliable equipment and backup aeration are essential given salmon's narrow margins.

Harvest & Enjoying Them

Coho reach harvest over many months, yielding rich, red, prized fillets excellent grilled, baked or smoked.

Getting Started

Begin with a proven cold RAS, redundant life-support, and healthy smolts from a reputable source; start small and scale as you master it.

Common Mistakes

Underestimating cooling and oxygen demand, no equipment redundancy, and biosecurity lapses are the serious errors.

FAQ

Coho or Atlantic salmon? Both are demanding cold-water salmonids; coho is a prized Pacific species with red flesh.

Beginner fish? No - among the most demanding to raise.
