The effect of salinity on survival and reproductive characteristics of four A. franciscana Mexican populations: Juchitán, Yavaros, San Luis Potosí, and Texcoco was evaluated. They were cultivated in 200 L beakers at 80, 100, 120 and 140 gL-1 of salinity concentration, at 25 ± 2 °C, with continuous light and aeration and pH of 8-10. The organisms were fed ad libitum with rice bran (50 mL) and 1 L of Tetraselmis suecica and Pinnularia viridis microalgae. When organisms reach sexual maturity, were separated in 25 glass beakers (200 mL), one female and two males to determine reproductive characteristics. The results show that survival and reproductive characteristics values increase with salinity in all populations. This information is valuable to understand the adaptation patterns presented by each Artemia population and can determined the biological basis for exploitation in semi-intensive crops to assure the demand that this organism has in the aquaculture and aquarium industry.
