brine shrimp hatchery

[amonhen]

This may be a bit off topic, but it seemed to me that folks here would probably know a lot about about hatching brine shrimp. I saw this in-tank brine shrimp hatchery at my lfs.

Seemed like a great idea, but I can't seem to find anyone with much experience with it. I did see see a juvi bs come out at the lfs.

When you purchase the eggs there are usually (if not always) instructions on how to hatch. However, many aquarists now feel that the nutrition derived from Nauplii is negligible.

Just about any container that can hold water can be used, just don't use something too shallow or you'll have trouble separating hatchlings from shells.

I guess I should have been more descriptive--I've hatched nauplii before. The selling feature of this hatchery is that it was an in-tank hatchery. Add eggs and water, hitch up an air pump and it will release the nauplii into your tank as they hatch. I like the idea of a gradual release of food into the tank, particularly in light of Ron Shimek's recent article about fish food in the natural reefs.

That thing will not work in saltwater tanks. It works in freshwater tank because it uses dense salted water in one compartment that hatches the egg, and the saltwater density keeps cysts in that compartment until they are hatched, and allowed to swim to the second freshwater compartment.

It's hard to explain in black and white, but it's a clever design. I never use it, but have helped my LFS set one up in store about a year back.

I don't buy gadgets for hatching artemia, I just use a salt bucket, rigid airline, and a cup of cysts.

I use this in my refugium and it works great. I did have to super glue the airline to the nozzle to keep it from blowing off but that was no big deal. Now if I could just keep the cardinals away from the overflow long enough for the inverts to capture some of the shrimp. :x
