Some biological and ecological aspects of Artemia salina from Chott Marouane (northeast Algeria) were studied during the wet period of 2001. The population develops between late winter and spring. It is adapted to the high salinity of the site, ranging between 230 and 360 psu. Sex-ratio is in favour of males. These are smaller in size than females: their respective average lengths are 6.02 and 7.01 mm. Oviparity is the main mode of reproduction (more than 86.6%). Females produce between 4.9 and 17 cysts/brood, according to the sampling period. Quelques aspects de la biologie et de l'ecologie d'Artemia salina du Chott Marouane (Algerie nord-est) ont ete etudies pendant la periode humide de l'annee 2001. La population se developpe entre la fin de l'hiver et le printemps. Elle est adaptee a la salinite elevee du milieu, qui varie entre 230 et 360 psu. La sex-ratio est en faveur des mâles. Ceux-ci sont plus petits que les femelles: leurs tailles moyennes respectives sont de 6,02 et de 7,01 mm. L'oviparite est le principal mode de reproduction (plus de 86,6%). Les femelles produisent entre 4,9 et 17 cystes/portee, selon la periode de prelevement.
