Scientific name: Artemia sp.
Class : Branchiopoda
Description: The sizes of Brine shrimp range from 1 to 10mm. The trunk has thorax of 11 segments, and abdomen of 8 segments. Brine shrimps do not have carapace. The head has a pair of large, stalked compound eyes and a single median simple eye.
Distribution: They are usually found in ephemeral ponds, hyper-saline lakes and marine lagoons.
Locomotion: Brine shrimp can swim ventral side by beating trunk appendages.
Food gathering: They use their trunk appendages to catch suspended food in the water.
Gas exchange: Gills in branchial chambers protect fairy shrimp from desiccation in inter-tidal regions. They can generate a ventilated current.
Reproduction: The sexes are separated, with eggs being fertilized internally. There is a free swimming nauplius larval stage in their life history.
Interesting facts: Brine shrimp can produce resistant, (cryptobiotic) fertilized eggs to accommodate unfavorable conditions. These shrimp are often used as live feed in aquaculture for larval or juvenile fish.
Aquaculture Research and Development Facility - The ARDF produces a wide variety of live foods for larval and juvenile fish and invertebrates, including algae, rotifers and artemia.
