Baby brine shrimp (Artemia nauplii) are perfect food for fry, juveniles and small fishes used as a diet supplement by many avid fish keepers for their nutritional value, and perhaps also the interest it sparks in their fish!
Enriched baby brine shrimp (BBS) closely duplicate the nutritional value of many of the small fresh water crustaceans found in the natural habitats of our fishes. They have the added advantage of being enriched by special micro foods containing extra vitamins and amino acids to condition most freshwater and marine tropical fish. Moreover they are free from freshwater parasites and bacteria since they come from water with heavy salt concentrations.
Storage, or holding live baby brine shrimp at cold temperatures, is a way of preserving the nutritional quality while maintaining a live food. Place the bags in the refrigerator. The baby brine shrimp should remain alive for a few days for later feedings. Cold storage of live BBS saves time and eliminates the need to maintain daily hatches of brine shrimp cysts. When newly hatched brine shrimp are stored at 4°C, their metabolism is slowed down considerably, conserving essential nutrients, lipids, and fatty acids that many fish and invertebrate larvae require. A lower metabolism will also slow down growth and maintain a smaller feed particle size for smaller larvae and fry. Later feedings of stored BBS is easy. Simply pour the BBS into a fine mesh net, rinse with fresh water, and feed.
