that's seriously expensive. i got a pound can for $36 and if you are ok with a lower hatch, the 80% gets as low as $20 a pound.
Seems like everything fishy is more expensive here in Australia, actually. I guess because most of it is imported since we don't have a large local population to support much of a home-grown industry. Anyway, those eggs were the relatively cheap ones, and maybe I do have to go to the more expensive ones.
If you want to be even more glad you're not in Australia, my LFS has some for $16AU (about $14 US) for a container of about 30g! (The online retailers are much cheaper than my LFS in nearly everything except actual fish.)
When I first hatched my Brine Shrimp eggs about 3 or 4 months ago, I let them sit for 24 (or a little more) hours, and I didn't think they had hatched. BUT... no one had told me the size the brine shrimp were going to be once they hatched. So I was looking for something MUCH bigger! But then I noticed that they actually DID hatch, only they were about the same size as the eggs and it was pretty hard to see them without a very bright light held right up to the jar. So if you don't have any experience hatching them, you might not think they are hatched but they really could be.
I hope this helps you and others.
I did realise they would be small and am looking carefully for the hatched shrimps, but not seeing anything. The system I am using is supposed to collect them into the container at the top anyway, since that is where the light is. But I've peered carefully into the black box and shone a torch into it too, to see if I could spot anything moving, and I haven't seen anything.
What colour are the hatched shrimp? I did see a few specks of red stuff that I thought might have been them, this last time. But a few hours later they were gone with no more appearing. Maybe they were dirt or something else. My eggs are brown, so I'm pretty sure I wasn't looking at eggs.
Anyway, I'm trying again this time with using bicarb soda to raise the pH to 8.2. I found a website suggesting that they like to hatch at pH between 7.5 and 8.5, and my tap water is about 6.6. So maybe this will make a difference. Also put a thermometer in to actually know what temperature I am heating the water to with my light. Will let you know if I get anywhere this time...
