They are very easy to hatch using just an airline, a coke bottle and a small air pump. You can raise baby brine shrimp to adulthood easily, too, if you have live phytoplankton. I have a container full of adult and baby mixture going for a long time (they breed and baby hatches in the container.) However, it is not the most productive culture. They take a long time to grow to adult size. Enriched frozen brine shrimp seems like a better choice than growing your own, unless you are trying to breed fish or shrimp.
