Re: [Killietalk] brine shrimp eggs and floating shells
Some viable eggs may also float until they absorb enough moisture to
sink. The reason for pre-wetting in soft or RO water is that the cysts
do not wet as readily in either very hard or strong salt water.
I don't do it, because they wet fairly soon, anyway, and a few swirls of
the inverted bottle will wash the few around the top back into the
turbulence. With good cysts, I get nearly 100% hatch with no wetting
beforehand. OTOH, I do use a lot lower salt concentration than many here
to get quicker hatching. If I used sea-water or stronger saline
solution, I would be tempted to pre-wet the cysts so they all hatch
My information came from the Chief Biologist at the SF Bay Brand plant
in Newark, BTW.
