Experience with decapsulated artemia cysts?

[Pszemol]

I have read about decapsulating of brine shrimp eggs in
http://www.advancedaquarist.com/issues/dec2002/breeder.htm
They say: "These decapsulated cysts can be hatched into nauplii
immediately, or dehydrated in concentrated brine solution
then stored for later hatching. Lastly, the decapsulated
eggs can be used for direct feeding. Decapsulated Artemia
cysts can be stored for a few days in the refrigerator
without any noted decrease in hatching."

Do you have any experience with decapsulated cysts?
How long can I store them after decapsulation/dehydratation
to make sure I will have major amount of eggs hatch nicely?

I have decapsulated my own, but never purchased any theat were decapsulated.. I
didnt find it was worth the efort to decapsulate. The cysts that I use will
hatch in less than 24hrs and one teaspoon of cysts yeilds at least a
tablespoonof naupalli. It seems like I get 100% hatch rate, but in reality its
probably only 90-95%.

Have you decapsulated them just before haching?
Have you got any experience with the storage of decapsulated cysts?

p.s. have you got my last e-mail I sent yesterday?

Thanks :-)) It was convincing what you said about
not being worth decapsulating - I have no big problem
of separating shells after hatching but I was just
curious how is the thing with the storage...
If I could decapsulate a pound of cysts in one batch
and then use them all over a year than it would be
worth it, but from the description I take they will
not survive decapsulated for more than a couple of days.
So it is not worth it unless you have very delicate
animals to feed.

Cool.

I dont know how long Decapsulated Cysts last but I have been using already
Decapsulated Cysts in a bottle.
They are in a liquid and a few drops gives hundreds of Cysts.
They are sold over the counter here in Australia with Hatcheries and also in
bottles ready for use.
They are alot cleaner to use than normal Cysts as there are no shells
floating around the top of the water.
I get near perfect hatch rates and dont refridgerate the Decapsulated Cysts
or do anything special.... This last bottle has lated me for ages...

www.ntlabs.co.uk is what address is written on the bottle.

Thanks - interestingly they say this product has very long shelf life.
I have to find a distributor of their products here, in USA...

I don't think the average aquarist has the ability to preserve home
decapsulated cysts for more than a short time. I do not know why, but I have
read it here and there... I personally do not feel like it is worth the
trouble either, since I am only "treating" my fish. Now if you are feeding
fry, then that is a whole other story...

It is not worth it to mess with eggs at home, but if you can get
decapsulated and hatchable cysts with long shelf life from some
supplier that is very convenient and clean.
Even if you treat only fish - you can pullute your tank with some
unwanted animals - I had once stinging box/cube medusas I was
writting here about. They must come with artemia cysts.

[Microbot]

Yes the standard way pollutes the water VERY quickly but these bottles of
Decapsulated Cysts in liquid that I use are a much cleaner way of growing
them, and they last for ages, you dont have to use them up quickly....
Hatching rate is great and they are ready to use alot quicker than standard
Cysts and the best part..... no shells. :)
And at my LFS here in Australia, the Decapsulated Cysts are nearly the same
price as the standard Cysts.....

I just bought a botle from the LFS.
"brine shrimp eggs with out shell" with a trade name of "NT laboratories"
they did come in a bow and with instructions but these have been put in the
bin.

short version of instructions
mix water with salt
add air stone
put six drops or so in the pop bottle
48 hours later feed fish

I have to strain them because im feeding them to a freshwater tank.


just found this http://www.ntlabs.co.uk/cgi-bin/quikstore.pl

I can only guess you are in UK...
I am looking for a distributor of this or similar product in the USA.
I have found some decapsulated cysts in US but they are not dedicated
to hatch but to feed with without hatching first.

the brand name Life-A decapsulated cysts are 90% cysts pre decapsulated, feed as is or
hatch and feed

you cant store decapsulated cysts for verylong 5days max ish in frige without dehydrating
them
it can be done and its not really hard 1g of cysts into 10ml of airated saturated brine
for a day, but ontop of that you need to topoff the salt every couple of hours. filter out
then storage goes for a few months easily. the overall % of hatchable doesnt change much,
you can increase that by filtering out the bad ones, but thats not as easy

if your feeding seahorses or fry you do really need to decapsulate before hatching
otherwise 1 or 2 shells wont hurt mostly.

The NT Lab Decapsulted Cysts can keep for longer than 5 days.
I've had mine now for a few months and they always hatch at what appears to
be close to 100% success rate...(of course it will be less)

They store the Decapsulted Cysts in liquid....
