Hi Carotenoid Marine Algae (D. salina)

The Hi Carotenoid Marine Algae (Dunaliella salina), is a rich source of antioxidants, carotenoids, vitamins, minerals, amino acids, polysaccharides, essential fatty acids, chlorophyll and phytonutrients.  It is a single celled, soft -walled, easily digested food source for zooplankton and larval fish. D. salina has successfully adapted to environments of extreme salinity and high UV exposure by protecting itself with high levels of carotenoids and anti-oxidant molecules. Although classified as a green algae, these adaptive mechanisms turn the algae a beautiful orange-red color. It is sometimes called red marine phytoplankton.


D. salina is nature's richest known source of dietary beta carotene. It is also a source of alpha-carotene, lutein, zeaxanthin and cryptoxanthin.  The color imparted by these carotenoids is assimilated by aquatic animals and birds.


Analysis: Protein, 8%; Lipids, 7%; Carbohydrates, 30%; Mineral (Ash), 48%; Moisture, 7%; Beta-Carotene, 1.1-2.1%; Other carotenoids, 0.13-0.24%; Chlorophyll, 2%.

Particle size: 10 - 20 microns.


Hi Carotenoid Marine Algae Mix is an ideal food for both artemia culture and for enrichment. To enrich artemia, hatch one gram Great Salt Lake artemia, harvest and transfer to clean seawater receptacle (approx 4 lt.). At 48-hours post hatch, add Hi Carotenoid Marine Algae at the rate of 0.5 teaspoon algae to 5 liters culture water. Before adding, place algae in a blender with approximatley one liter of clean seawater and blend until clumps disappear. Add to culture. Allow artemia to gut-load for 6 - 12 hours. Harvest artemia and feed.  Excellent for augmenting diets of marine fish larvae and seahorses. Can also be used to enrich copepods.


Hi Carotenoid Marine Algae Mix is frequently incorporated into DIY diets at the rate of 1-2% dry weight, resulting in a beta-carotene content of 100-200 ppm, suitable for enchancing the coloration of fish and shrimp. Excellent for augmenting maturation diets.  Can also be fed directly to filter feeders, including coral.


D. salina should be stored in a tightly sealed container in a freezer to prevent oxidation.
