Coffee filters?...My only gripe is that the mesh size of recent nets is coarser than older nets and some shrimp slip through. I hate to think what I'll use when my 20 year old brine shrimp net dies.
Here is what I do....
2-liter bottle bubbled from the bottom (I use one of the commercial hatching bases designed for 2-liter soda bottles).
Non-dechlorinated WARM tap water (very warm... but not too hot to touch)
2 tsp. sea salt (any commercial marine salt... cheapest I can find)
1-2 tsp. cysts
In my fish room I get maximum hatch at about 18 hours.
Unfortunately no pics of it in action 'cause the emphasis is on "had". When I lived in Florida I could keep the arrrangement outside in a shed, but there's no room where I am now. So much air-driven water does tend to throw a little salt crust outside the tanks as it bubbles.amazing!! i wish I had a system like that. mind posting some pics??
https://picasaweb.google.com/Ekona12/Artemia#Hey Ekona. Is it possible for you to post a couple close-up pictures of the dish so I could build my own? I saw that and thought it looked extremely interesting but all the pictures/photos online were too fuzzy to make out the ring patterns in the inside. Thanks.
Yeah, same thing happened back about 2000 or so. Ended up having to pay $100+ for the one-pound bags at the time, and that was ten years ago...Since we are on the topic of brine eggs... the 2012 harvest in the GSL is horrible. The projections are for 50% of 2011 (a very average year). There is no danger to the shrimp population... the up and down cycles are normal. We can expect to see a significant increase in cost for GSL brine eggs in 2013. The price of a pound of grade A (80% hatch... which is what I use) from Brine Shrimp Direct is already up to $42/can (from $30 a few months ago). I would not be surprised to see GSL eggs go up to $60/can next Spring/Summer as stocks dwindle. Foreign eggs from China and Russia will become increasingly available at lower prices (BSD is going to import some to offset their low harvest), but hatch rate of those eggs is notoriously inconsistent.
I advise buying cans for 2012 right now...
CopabX, the link works when I click on it, so I don't know why it is not working for you. But sorry about that. (It may be that Picasa is a Google thing, and you might need a Google account to view them??)Unfortunately the link http://picasaweb.google.com/Ekona12/Artemia# doesn't seem to be working, it says page not found (Josh, hope you get the picture functions up soon!). As for the reasoning behind me trying to build one, I agree that $25 really isn't that much for something that seems to work so well, but not my parents. They already think I'm insane for buying such a high maintenance fish and are currently complaining about the bubbling from my 2 liter setup (I find it calming). Also the tray idea seems to be much easier to heat with a reptile mat of some sort than the bottles. It's getting pretty cold here and soon I won't be able to hatch anymore shrimp and my fish will go back to a frozen diet, kind of ironic. :biggrin: I wish I had a fish room that stayed 80F all year around but it's either my room the basement or none.:frown:
Ekona, thanks for the pics. I'm guessing it works by allowing the hatched shrimp to swim through the openings at the bottoms of the ring dividers and make their way towards the center?CopabX, the link works when I click on it, so I don't know why it is not working for you.

Try this link to a website with pretty clear pictures of the system: http://reefbuilders.com/2009/11/12/brine-shrimp-hatchery-hobby-separates-egg-shells-moving-parts/
