Artemia (brine shrimp) are good food for larval fish, but they have to be removed from their shells before many species can eat them. The process can be time- and labor-intensive, especially since it is often performed every day. Fortunately, this 3-page fact sheet written by Jason Broach, Cortney Ohs, and Isaac Lee and published by the UF/IFAS School of Forest Resources and Conservation, Program in Fisheries and Aquatic Sciences describes a method for storing a 7-day supply of the brine shrimp that will allow the task to be done just once a week.
