The brine shrimp hatchery by Hobby is another fine aquaculture product brought to you by Brine Shrimp Direct. The ingenious design of thisÂ Artemia hatcher incubates up to 1/4 teaspoon of brine shrimp eggs. The circuitous design requires no power, it has no moving parts but it automatically separates the shell from the newly hatched Artemia nauplii. The eggs are added to the outer ring of the hatchery which is completely covered except for a hole in the center. Since the Artemia nauplii are attracted to light, they migrate slowly towards the center. The newly hatched brine shrimp must navigate through a series of baffles before treaching the center, leaving their egg shell behind. After 24 hrs at 72F, most of the nauplii will accumulate in the center, where they can be easily removed using the included microsieve. Hatching large quanitites of brine shrimp is still way more efficient using conventional methods nut for aquarists looking for an easy, no hassle method for feeding fresh Artemia nauplii to corals and reef fish, the automatic brine shrimp hatchery and egg shell separator is about as easy as it gets. The Hobby Artemia hatchery is available from Brine Shrimp Direct for just $23.95, more pics of the hatchery after the break.
