This paper summarizes the results of a study that comprised a survey along with a morphological characterization of Artemia populations from seven sebkhas, one chott, and an inland salt lake in Algeria. Sebkhas and chotts are two different types of closed inland basins. Morphological characters together with a multivariate discriminant analysis applied to morphometric data obtained from adult specimens cultured under standard conditions, were used to differentiate the species and strains. The bisexual species A. salina (L., 1758) is present in seven of these saltmarshes, but frequently cooccurs with diploid and tetraploid parthenogenetic strains. The biodiversity pattern of the populations of Artemia in Algeria appears to be similar to that found in the rest of the western Mediterranean region.
