Raising Atlantic Salmon in Land-Based Systems

Atlantic salmon is the premium fish the world farms most, and increasingly it is raised in land-based recirculating systems rather than sea cages. It rewards you with prized, rich fillets, but it is one of the most demanding species in aquaculture - cold, pristine, oxygen-rich water and heavy-duty filtration are non-negotiable, making it a project for the experienced.

Is it right for you?

Salmon suits an experienced aquaculturist with a well-built cold recirculating system, not a beginner. The payoff is a premium fillet, but the water-quality demands are exacting.

System & Space

A large, well-engineered recirculating system with reliable chilling, oxygenation and biofiltration is required; salmon need space and pristine conditions to grow out.

Water & Temperature

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

Stocking & Feeding

Stock size-graded smolts and feed a high-protein salmonid diet; grade regularly. The heavy feeding demands filtration that stays well ahead of the waste load.

Health & Care

Water quality is everything - cold, oxygen-rich and clean prevents most disease. Biosecurity, reliable equipment and backup aeration are essential given how little margin salmon give.

Harvest & Enjoying Them

Salmon take many months to over a year to reach harvest size, yielding the rich, pink, prized fillets the market values highly.

Getting Started

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

Where Keepers Go Wrong

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