How to harvest brine shrimp

[Molch]

I bought this mark the seller cheated me to me, "I said to myself that this brine shrimp hatched mark. The problem with this brand is not moving, are hatched preserved.

it's pretty clear from the description of the product that they are not alive, but preserved. I'd worry a bit about what has been used to preserve them, such as a high salt content which cannot be washed out of the nauplii maybe...?

Brine shrimp eggs are well preserved and these are very easy and quick to hatch, there are many advantages, I think is a great live food.

Yep, back to the drawing board. Those are just preserved, not live. They might work well for fish but not newt larvae. Told you it was too good to be true...

I think the worst thing is the bubbling. After a while it just became another daily routine to hatch and harvest so I didn't mind really.
I was also thinking about daphnia originally but artemia seemed like a much easier option for me.

I was getting the Water Life decapsulated eggs like Kroak at first but the small bottle only lasted for a couple of batches - perhaps my methods weren't the best.
I got a large pack of normal eggs from ebay afterwards and never even used them up.
I don't know if any larvae suffered after ingesting shells - a couple got bloated but who knows why.
I also used frozen bloodworms for larger larvae but they are rubbish for colouration so I wouldn't recommend feeding them too often (to Cynops at least).

The mosquito larva I use a 40/50% in the diet of the larvae, I have given a satisfactory result in cynops cyanurus good color but not very well in Triturus karelinii.
"I think the cause depends on many strains of captivity?

I’m going to try hatching daphnia from eggs for the first time this year in addition to the usual brine shrimp. The eggs/ephippium are more expensive than brine shrimp but there are obvious benefits to fresh water prey. I’m also going to try culturing banana worms, which apparently are very prolific and even smaller than BBS.

Acouple of tips with regard to feeding BBS to larvae;

1) Throw in some small snails to help with clean up. They can't really compete with the larvae while the BBS are alive, but do go after the BBS once they expire.

2) Put some Hornwort or some other fast growing plant that doesn't obscure your view of the larvae. It does a great job of helping use the ammonia and other by-products of digestion, and is also useful should you forget your water change.

Have you tried feeding microworms? They eventually rest on the bottom and so are in the larvae's "feeding zone", are accepted eagerly by any larvae I've raised, and live for days in the water should they not be eaten.

I tried microworms but my C. pyrrhogaster larvae didn't seem very interested. I suspect they are a bit too small. I had them more as a back up plan. They are definitely very easy to culture.

Even that it's Dutch, I think the pictures are quite clear.
Breeding Artemia

I use the same set-up, only I don't have them hanging somewhere, but put the breeding bottles into a soda bottle from which I removed the top.

To harvest them, I put the air off and put half a liter water in it. Then I let it rest for at least five minutes. Then three layers are made within the water: in the top the shells, in the middle quite clean water and on the bottem living brine shrimp. Turn the tap open above a bottle, and you close it when you have enough or you are passed the line between the living brine shrimp and the clean water.
