Of the various algae grown in the St. Croix Mariculture System, the diatom Chaetoceros curvisetus (clone STX‐167) proved to be an excellent diet for culturing Artemia nauplii and adults. The minimum cell concentration at which Artemia can efficiently remove cells has been determined and appears to be constant throughout the brine shrimp' life cycle. The cell stripping efficiency, growth rate, and survival of the different larval instar stages have been studied in function of increased stocking densities and flow rates. The results obtained in 230‐liter raceway tanks, subsequent to the initial 190‐liter tank studies, and extrapolated to a one m 3 system indicate that 15 g of cysts (4/ml animal stocking density) can be converted into 8.7 kg of fresh weight adult Artemia in 14 days.
