DE LOS RIOS, Patricio. Crecimiento en poblaciones de Artemia franciscana y  A. persimilis (Crustacea, Anostraca) en condiciones controladas. Rev. biol. trop [online]. 2001, vol.49, n.2, pp. 629-634. ISSN 0034-7744.

Growth (length), was compared in A. franciscana populations  from Utah, United States of America, and Yape, Chile, and A. persimilis (population from Salinas de Hidalgo, Argentina), cultured under controlled conditions (24°C, seawater 35 g/l, feeding with Chaetoceros calcitrans). There were significant differences among all stages of A. franciscana (Utah) and A. persimilis, whereas we found significantly differences only in two stages of A. persimilis and A. franciscana (Yape); both A. franciscana had similar total lengths in all stages analyzed. Habitat adaptations could explain these results.
