BALANCED ARA/EPA RATIO IN SALMON GILL AND KIDNEY TISSUES TO IMPROVE SEA WATER PERFORMANCE

摘要

The present invention describes a salmon smolt comprising an arachidonic acid (ARA) to eicosapentaenoic acid (EPA) ratio of one or greater, specifically in gill and kidney tissues. The invention discloses a feed additive containing ARA and its use in a sufficient amount to balance the excess amount of EPA contributed from the marine oils used in the standard feed for salmon. The invention also discloses a method to modulate the gill and kidney ARA/EPA ratio to the favor of ARA. Smolt of the present invention demonstrates superior growth recovery and stress resistance after their sea water transfer.
