Abstract: Potential production of four Mexican populations of A. franciscana were obtained in laboratory at different salinities (80, 100, 120 and 140 gL-1) culture medium in 200 L beakers at 25 ± 2 °C, with constant light and aeration and pH 8-10. Strains were fed with 50 mL of suspension rice bran and 1 L of
Tetraselmis sp. and
Pinnularia sp. microalgae culture. When populations reached sexual maturity, they were separated into 25 vials of 250 mL (one female and two males) to determine nauplii and cysts production. Broods produce were 7-11/13-16, nauplii 46-54; 57-66 and cysts 52-65; 67-85 by female increased with salinity. Nauplii production decreases at 140 gL
-1 salinity (38-45 per female). The productions obtained were 273-411 g biomass in 120 gL
-1 salinity and 4-7 g of cysts in 140 gL
-1 salinity. This information can allow potential productions of these organisms in semi intensive culture ponds in their own natural habitats.
