I had no clue so I googled it...
Golden Pearl is a revolutionary new larval diet that has successfully replaced live Artemia nauplii in marine fish hatcheries in Europe. A patented processing technique (agglomeration of micro-encapsulated particles) resulting in feed particles or "clusters" that resemble raspberries (under the microscope). Golden Pearls have tiny air pockets that keep the feed particles in the water column, not on the bottom of the tank. Golden Pearls mimic live brine shrimp nauplii.
