These eggs are probably from Daphnia magna. The stuff you see in the bottle is basically sand or soil, with the resting eggs within.

I have just come across this piece of sad 'news' from a respectable article source about Giant Russian Daphnia:-
" ..This colony has for 40 years been consistently propagated at approximately 70 degrees F. and has apparently lost its ability to enter a sexual stage and produce resting eggs when stressed.. "
So it would appear that it is near impossible to get the eggs of this species, though live cultures can still be bought in the west.
If anyone has live 'big bad boons' (magna) to sell, I wouldn't mind paying through the nose for a bag of it. Knowing the difficuty of cultivating them.
I have not much interest in moinas, though I have casually bought a few bags already so far.
Since I have totally no experience with raising boons, I am not keen to buy the resting magna apphibia cysts even if it is available here.
But of course I will be only too willing to share the cost of such epphibia if anyone will be able to do the hatching.
No offense, but what you said almost sounded like sex without strings attached!! However, like many things in life, there are no free rides and no achievement without taking risks, making needed compromises and learning along the way.
Ted, from the beginning of this thread, I never once stated that culturing Daphnia was easy. If it was, I would have had it made by now. What I can do, is walk alongside those willing to take the challenge and try, and try I will too.
I'm curious though. What good can one bag or tub of magna do for you if there's no attempt to provide a conducive environment that allows propagation?
If you're adamant to ship live cultures, go rope a few others in to share EMS shipping costs. I'm game for a share of the loot.

Ted, hatching the ephippia is the easy part.. storing them is not.

I must agree with you and Ronnie that it is a delicate and demanding task to keep a sensitive daphnia colony going strong. If not, it would have been easy for anyone to just buy a bag of giant boons every other day at the local fish shop. I am surprised to find so much information about boons and boon culture with google search.
In the meantime, my little Tetra friends are eating the wee wee moina dots with some gusto. With Magnas, I am sure they will go hysterical with glee in gobbling them up one by one at super speed.
My conclusion is that Magna culturing is a dedicated job in which one must love one's daphnias more than one love one's precious fishes. Nothing less will make them happy. They are much, much more demanding of attention and loving care than the fishes.

On this note, I'm going to try my hand with some Triops. They look like cool pets.

But succeeding at Magna boons is more challenging though. It's something like climbing Mt Everest.... not impossible.

Triops produce nauplii too just like BBS and Fairy Shrimp. I've seen live fairy shrimp being sold locally before. The fellas over at Betta Club Singapore showcased these shrimps before at a previous Aquarama. They were raised from dirt with ephippia shipped from Thailand I think.
D. magna seems to be a temperate species, so in our tropical climate, it's a waste of time to culture them when Moina is already a challenge. You'll get a bigger snack for your fish with grindalworms instead of D. magna.

Triops may be the next big thing, though, like shrimps are at the moment, and big-bump loahans were only not too long ago.
Re the Magnas, do you think the temperate climate can be simulated indoors here?
Haha they might, but the fact that they live for such a short period of time could be a deterrent. Imagine, you had only just got to know it. And not to mention you can't keep them with any smaller animals, they are known to attack them.
About Daphnia, I just recall that long ago I had an old relative who used to rear fishes. In those days, one can commonly find huge red boons in the many ponds everywhere.
If one say the climate here is too hot for giant Magnas to thrive, then how come they could be found here in the past? I remember quite vividly as a child that one can scoop those huge red daphnia with a net. And the amount caught is so much that one can casually use a finger to scoop up a huge lump of red daphnia from the net to feed the fishes.
Er... Global warming? Whether you believe that or not, the fact is average daily temperatures have been rising in Singapore. Anyway a pond setting is different, plenty of aeration, plenty of cool places that the sun cannot heat up in the pond...
In the past, ponds would be fringed by trees and vegetation much like the one at Farrer Park, near KK Hospital. So their temperatures would be cooler than you expect for modern ponds these days with no overhanging trees or branches to filter out the light. Also, temperature differs in a pond according to depth. Warmer when it's shallower, cooler when it is deeper. The reverse happens in winter for temperate countries.
"Increasing population density and urbanization in the island-republic of Singapore have motivated techniques for highly efficient pond culture of Moina micrura for Singapore's aquarium fish farms, using wastewater from pig farming. You'd think that these large-scale daphnid culturing techniques wouldn't be very relevant to your aquarium concerns, but I noticed in a document now removed from the University of Singapore website that they drain the meter-deep ponds and let them bake dry in the sun every three months or so, to eliminate competing organisms like hydra and copepods and ostracods, which have no drought-weathering stages."
Taken from http://www.skepticalaquarist.com/daphnia and which can be confirmed in a FAO document by the UN. I read this in the library of SP when I was a student.
As for those "big boons". Perhaps we had a native Daphnia species, or Bosmina, or perhaps some other cladoceran that may have existed in dirt ponds in the past, but with urbanization, to find such ponds is a rare occurrence. Most of the ponds we see now are artificially made, and do not contain these cladocerans. To be sure of what species your relatives were feeding their fish with in the past, you'd have to ask the people at NUS who may have records of native Daphnia species. You cannot say with 100% certainty that those "big boons" collected in the past were D. magna, without a verifying record of their existence on this island as native microfauna.

4 things come to mind. Global warming, destruction of flora, illegal introduction of non-indigenous aquatic species and no pockets of pig farmers.
Ted, if you're patient, keep an eye on this thread. I might have something cooking up my sleeves...

It is highly possible that the big boons of the past were Bosmina or other species which may have been 'extinct' here over time.
In view of the frantic manner in which small and not so small fish can go gaga over these delicacies, big red beady Boons are definitely worth the effort to cultivate,
as one can expect Tetra lovers, (also other fishes, eg Discus), to not mind paying hefty prices to pamper their valued pets.
And have you guys noticed how some LFS owners say that the gah*cough*men don't allow the sale of big bad boons anymore? The one that was at block 85 said so, in case anyone wants a source
Really? That's rather strange. Why is that so? Care to make some enlightenment?
