Re: Finally Good Hatches
Once the bbs (baby brine shrimp) hatch, harvesting is pretty simple.
Normally, the now empty shells float at the top and the nauplii
(baby brine shrimp) swim all around the rest of the available water. Some
people build covers that only allow light to enter at a specific spot near
the bottom, because the bbs are phototropic and will swim toward the light,
bunching them up in one spot. Others (like me) just let them alone while
the shells float.
I usually withdraw the air and let the hatching container (a 2 liter
soda bottle for me) settle for about 10-20 minutes. Longer might allow the
oxygen to be depleted and have the bbs die. I blow through my siphon tube
until I get some condensation in it. Then I put the end in the bottle and
let a drop or two of condensation fall on the surface of the water in the
hatching container. This usually makes a clear spot big enough to insert my
siphon tube through without disturbing the floating egg shells much. Then,
I siphon the water out from the bottom into a fine net.
I then take the net and drain most all of the salty water out. I
fill a small plastic cup with fresh, unsalted water (treated for chloramine)
and dip the bottom of the net into it. This rinses the bbs, while still
keeping them in the net. I use a baby dropper to feed the rinsed bbs to my
fry and to some adults that seem to need more live food than others to spawn
well.
This method works well for me. I'm curious to see if anybody has
any significant variations. I do not raise any bbs into adults as frozen
are easily purchased and used instead. I don't keep them alive any longer
than necessary to feed them to my fry while they still have maximum
nutritional value.
