Abstract
The brine shrimp Artemia in Chile has been studied since the 1980s, initially on populations inhabiting shallow coastal and inland mountain ponds, and saltworks in northern and central Chile. Based on morphometric and molecular evidence, these populations were identified as A. franciscana. In the 1990s, A. persimilis was recorded from southern Patagonia, a species previously considered endemic to Argentina. Recently, two new populations of A. franciscana have been recorded, from one saline coastal pond in northern Chile and from a saltwork in central Chile. The scope for further research to increase both understanding of the strain characterization and basic population ecology descriptions of the Chilean brine shrimps and improve their conservation status is discussed. It is suggested that future studies should investigate first the management of local brine shrimp population for local aquaculture or conservation resources, other direction would be the effects of ultraviolet radiation (UVR) exposition that is notoriously high in brine shrimp habitats. This last factor is very important because the UVR is an important mutagen on the genetic structure of the populations. In this scenario, it is suggest a carefully management for introduced brine shrimp populations for local aquaculture for avoid alterations in native populations that due their genetic isolation would need conservation procedures for avoid local extinctions.

Summary
The brine shrimp Artemia is a cosmopolitan crustacean inhabiting saline lakes and ponds in all continents with the exception of Antarctica. Prior to 1996, A. franciscana was reported from inland and coastal shallow ponds and one saltwork (Amat et al, 1994b, Table 1 and Fig. 1). In 1996, one population from a saline shallow pond in southern Patagonia (Campos et al, 1996) was reported and identified as A. persimilis (Gajardo et al, 1998, 2000; De los Ríos & Zúñiga, 2000; Table 1). Two more populations of A. franciscana have been reported, from a saltwork in central Chile (De los Ríos, 2000, Table 1) and from one shallow coastal pond in northern Chile (Crespo & De los Ríos, 2004). One population of A. persimilis from a saline lake on Fireland Island (De los Ríos, 2005; Table 1) has been discovered
