Nanoemulsified blend of sustainably-harvested marine oils high in Omega-3 and -6 highly-unsaturated fatty acids, choline, and astaxanthin, fortified with immunostimulant compounds, feeding stimulants, B-vitamins, and seventeen critical free-form amino acids provided in a specific ratio for marine fishes and suspension-feeding invertebrates. Does not incorporate: pH-modifiers; artificial preservatives; chemical emulsifiers; artificial colors; marine collagen (which is unsustainable); or oil derived from elasmobranchs (which is unsustainable). Consumption of Omega-3 and -6 HUFAs generally elicits tissue growth and regeneration in marine fishes. Immunostimulants, choline, and free form amino acids are associated with improved robustness. Astaxanthin consumption generally elicits greater color intensity. Refrigerate for maximum longevity of active components. Emulsified oil mixtures are typically rich in organic material, requiring considerable alteration of mixture pH and addition of preservatives to maintain shelf viability at room temperature. By their very nature, preservatives are intended to suppress bacterial growth or outright eliminate it, and in either case it is not ideal to intentionally add these compounds to a living ecosystem. While NEMO+AA will remain viable for a period of up to one year from the date of production when maintained free of contaminants and at 70°F, refrigeration will significantly increase the life span of this formulation.
