Eggs, mother too young/small?

The first one hatched!!

I'm still thinking if I need to relocate the larvae into smaller places. What is the advantage of that?
And how do you catch them?

The brine shrimp I hatched are all doing well now.. but how long can I keep them? They are about 3 days old now.. are they still good tomorrow?
Should I add them to my axies now?
 
the fewer larvae in each container the better as this will help your cleaning.
they do not normally need to feed for a couple of days as they have yolk in their tummies.
always make sure you rinse the bs before adding any to your larvae as the salt is harmful.
you can try some as soon as they are hatched but make sure you remove any uneaten that day as they pollute the water.the easiest way to catch them is with a turkey baster
good luck
 
you can use it for both but most people strain the bs in a net, if you havent got a fine net try a hanky or the toe out of a pair of tights, just dont forget to rinse them.
 
I was going to try using a tea spoon to move them, but I hadn't appreciated that the larvae are jet powered. So i used the turky baster and it works very well.
 
Got 6 of them now.. I'll search for a turkey baster somewhere (I only have smaller laboratory pipets).
I'll put them in a smaller home when I find one.

Any tips btw how to separate the eggs from the brine shrimp? Also a Turkey baster?
 
Well.. from the 13 that hatched, 10 have survived up to now.
Since I had trouble hatching enough brine shrimp I made another hatchery today. I hope I can keep the supply up.

Is there any way to transfer the axies to a clean tank without taking a lot of debris with them?
With my turkey baster thingy I also take a lot of brine shrimp eggs with the axies.. so I'm fouling the water immediately I think.

How long can these kiddo's go without food? Do they need a constant supply, or can they do a couple of hours without food?
I'm in a bit of a pinch here, since I only had 1 hatchery for brine shrimp and I couldn't keep up with the demand. The axies now have a few brine shrimp that my hatchery produced in half a day to keep the axies eating. The 2 hatcheries should be able to keep up with the demand, but can they survive the couple of hours without food?
 
yes they will be ok for a couple of hours they would be fine with two feeds aday as long as they have enough at each meal.
i have never been successful with brine shrimp myself which is why i go with daphnia, this can be kept in with them permanently as they are bred in fresh water.
this also means food on demand for them without the same risk of it dying off and having to be removed.
 
When I raised eggs, I kept them all in small tubs. I poured out most of the water and debris, and gently poured the baby into the new bucket of water. I did daily water changes.
 
the tub mine is in is about 20cl...very small.. I'll try your way next time..
I'm planning on doing a waterchange twice a day.. since it looks like it's getting dirty really fast.
 
Although they may grow faster at warmer temp, I wouldn't say it's better for them. Even larvae are at higher risk of problems if they are over 21C. They eat and grow quite well at 15-20C. Keeping the container on the floor will keep it cooler. A cellar would be even better, if possible.

I'm not surprised that a young female would lay only a few eggs. That seems quite normal, particularly if she is average weight, not fat. Mine lay only a few eggs at a time (<100), probably because I feed them less than most people do. Of course... maybe they eat some of the eggs before I get there:cool:

BBS (baby brine shrimp) are most nutritious during the first day or two after they hatch. After that, they decrease in nutritional quality. As long as they are still alive they are still an acceptable meal, though. BBS die in fresh water within an hour or so. It is sufficient for the larvae to feast once or twice a day, and go w/o food the rest of the time.
 
2 more have died today...
From the total of 13, I've lost 5 so far. Is this normal, or are there other factors at work?
 
i know this may be a strange question to ask, but are you rinsing the bs in some dechlorinated water before giving them to the larvae as the salt they are bred in is not good for the babies.
also individual containers will enable you to keep a closer eye on who is and isnt eating as well as keeping them cleaner.
 
dechlorinated is best. i use the tank water to rinse any foods i feed my larvae and juvies.
also if the eggs are not shellless you should sieve them to remove shells.

What can I use to sieve them? Those BBS are about the same size as the shells, so either both can pass through or none can...
 
as i said before i dont use brine shrimp as they have never been successful for me.try sending kaysie or kapo personal message as they seem to have the most know how,
sorry i cant help more
good luck
 
I'm afraid I'm no help here, as I used daphnia as well.
 
okay this is what ive heard from someone who breeds fish.
they cover the top of the brineshrimpery with something dark, turn off the air for approx 5 minutes.
they then shine a torch at the bottom and apparently they swim down leaving the eggs floating at the top.
they then open the valve on the airline and release the bs into their net or stocking,then getting some water from the tankyou rinse them and add them to your larvae.
i hope i explained that ok
good luck.
 
There is 1 thing I don't really understand:
how do you get the BBS out of the bottle?
I have plastic bottle with a cut open top. There is an air hose from the top to the bottom.
To remove the BBS, do I have to use that air hose to suck the lower part of the water out of the bottle? And how do you do that without sucking the water out manually through the air hose (so that the hose is filled and the bottle empties itseft due to the gravity or something)? I really don't want BBS in my mouth :p
