Re: [Killietalk] brine shrimp salt

[Brian Watters <bwatters at shaw_ca>]

I re-use my brine shrimp water for up to about 5 weeks and have always done
so. The trick is not to overload the hatcher with eggs. I have three
hatchers - one liter round-bottom laboratory flasks - that I operate on a 36
hour cycle. They are arranged in series with strongly bubbling air flowing
through. When I harvest the shrimp I allow a few minutes for the egg shells
to separate and then I syphon off the water with shrimp through a fine net.
I rinse out the flask and pour the (now filtered) brine solution back into
it and add eggs. I can usually tell to within a day or so when the brine
solution needs renewing because the hatch rate will suddenly drop off
dramatically. At that point I make up a new solution for all three flasks.
The old brine solution goes down the drain and since I am doing that so
infrequently I don't feel guilty about it. Incidentally, I use marine salt
when I make up the brine solution. I find that works better than ordinary
NaCl.
