RE: [Killietalk] RE: Hatching brine shrimp

["Lorraine Overall" <overall077 at lycos_com>]

I can get good hatches in 24hrs by decapsulating the eggs. I decapsulate a whole load at a time and store them in hypersaline water in the fridge. I don't measure salinity in the hatching water, just guestimate the salt, it doesn't seem to matter how much salt I use, I haven't tried with a lot of salt though. I use the inverted soda bottle method. 
With my methos there is no need to worry about separating shells.

just me 2c worth.
