Abstract: Biomass of the crustacean Artemia sp. has multiple uses. The biochemical composition and biomass production of Artemia grownfrom cysts produced by a native population from Real de Salinas were evaluated under laboratory conditions. Nauplii (instar I) were stocked at density of 10 nauplii/ml in 1.5 l tanks, fed with ricebran from day 2 to day 6, and with the microalgae Tetraselmis suecica from day 7 to day 15. At the end of the trial (day 15) the average length was 5.34 mm, biomass production was 15.72 g/l (wet weight),and survival was 79%. The proximal analysis and biochemical composition of Artemia biomass indicated that its nutrient percentages are closely similar to Artemia from other regions, making thisspecies a suitable food for cultured fish and crustacean.

Key words: Artemia, biomass production, biochemical composition, brine shrimp, culture, Mexico.In Mexico, aquaculture activities are currently expanding. Campeche is a coastal state in southern Gulf of Mexico where aquaculture is gaining importance. Some endemic finfish and crustaceanspecies seem to have aquaculture potential, but live food availability is one of the major constraints for the culture development of these species. Studies on native Artemia populations represent an...
