In order to explore the smoltification technology of all-female Atlantic salmon(Salmo sal-ar),a test was conducted in land-based recirculating aquaculture system.After 3 months,a total of approximately 65,000 juvenile salmon were smotificated successfully with a smoltification rate of over 95%,a survival rate of 97.4%and a mortality rate of 0.7%within 30 days after transferring into the seawater.A technology for smolting all-female Atlantic salmon with simple operation,higher sur-vival rate and smoltification ratio,and more robust smolts has been formed.
