TAXONOMY
Artemia salina Linnaeus, 1758, England; and a cluster of about 10 associated species.

OTHER COMMON NAMES
French: Crevette primitive, singe de mer; German: Salzwasser Feenkrebs, Salzkrebs, Urzeitkrebs.

PHYSICAL CHARACTERISTICS
Brine shrimp refers to Artemia salina and about 10 different associated species. They are slightly small anostracans, reaching solely 0.6 in (15 mm) in size. The colour varies from virtually hyaline and clear to shiny pink. The male antenna is strongly modified, however is just not adequate to determine the species. Microcharacters are required for identification, in addition to biochemical and molecular strategies.

DISTRIBUTION
The unique specimens of A. salina have been sampled from salt works at Lymington, England, however that inhabitants has lengthy been extinct. The genus is widespread in our bodies of salt water on all continents, and was launched to Australia within the twentieth century.

HABITAT
Natural or synthetic salt lakes and salinas (saltwater marshes) worldwide.

BEHAVIOR
The habits of this species is analogous to that of Sudanese fairy shrimp.

FEEDING ECOLOGY AND DIET
Artemia is a small-particle filter feeder. It could be grown on algae, yeasts, and all kinds of micronized inert particles.

REPRODUCTIVE BIOLOGY
Like all fairy shrimps, artemia develops quickly. The time between the hatching of the nauplius larva and maturation is barely longer than every week. Artemia can be famous for its reproductive flexibility: below favorable circumstances, it produces clutches of eggs at shut intervals. Some species and/or strains could reproduce parthenogenetically, whereas others are viviparous. Artemia is the one identified genus of fairy shrimp that reveals this diploma of versatility in reproductive ways.

CONSERVATION STATUS
Not listed by the IUCN. The typical locality of the true brine shrimp has lengthy disappeared; consequently, there's some uncertainty as to what constitutes the true habitat of Artemia salina, though it's possible geographically widespread. Artemia monica (Verrill, 1869) is one member of restricted incidence. This member of the genus is proscribed to Mono Lake in California, the place measures have been taken to forestall large fluctuations within the salinity of the lake.

SIGNIFICANCE TO HUMANS
It has lengthy been identified that the presence of Artemia spp. (and of Parartemia as nicely) improves salt manufacturing in brine swimming pools. That precept remains to be broadly utilized in salt works. In addition, an trade of Artemia cyst harvesting has developed round giant salt lakes (Great Salt Lake in Utah, Kara Bogaz Gol within the Caspian basin, and others), the place these cysts float in giant plenty on the floor of the water. The cysts could be collected in nets or scooped up from the lake shores the place they accumulate. These cysts are later hatched to feed fish larvae, both in industrial aquaculture or by aquarium hobbyists. There are additionally a couple of situations of direct human consumption of brine shrimp, the best-known instance being that of the Dawada (worm eaters) tribes within the Fezzan desert of Libya.
