Live food: fairy shrimp

Old thread, I know, but probably better than starting a new one. I just wanted to add that I have an incidental culture of fairy shrimp in my tubifex/snail culture that seems to be growing well. It's a seven gallon acrylic hex with a UGF tube floating vertically stuffed with nylon mesh as a filter. I almost never change the water, in effort to make sure the bacteria remain numerous. Eggshell and mussell shells keep the pH up. I put a tiny amount of fish food in there daily, along with bits of leafy foods and tuna chunks. There are more turbo snails than anything else, a few ramshorn snails (the tiny kind) and a solid carpet of tubifex or detritus worms living in the snail waste. Swimming in this soup is a now rapidly exploding fairy shrimp population. I see them mating, and the weird nymph-like phases are kicking around looking more like daphnia than anything else. No daphnia, though. They died off in the first few weeks. This culture is about five months old. Anyway, I'd just confirm the thin-shelled (summer eggs) idea. My house is warm, which may or may not have anything to do with it, but I'm getting an army of these guys as we speak, which is good news for my surprise angelfish fry... So now comes the question...can I move this process to the fry tank? It would be great to have the fry living in the shrimp cloud!

I know this was old threat here, but have you already find out how to make continuous colony of the Fairy Shrimp producing Summer Eggs? Would like to know your research progress. Since I don't have any information yet on Summer Eggs.

My further research indicates that one of the triggers for the shrimp to switch from summer to winter eggs is rising salinity, which in the wild would indicate a falling water level and imminent dryout of the pool. If you never change water from your culture vat I would expect ultimately that they would stop producing summer eggs as nitrate builds up in the water.

I have mine in a 20 gallon Rubbermaid with a thin substrate of crushed oystershell to provide pH buffer and calcium. This culture is only about two weeks old. I see some adults swimming about with eggs, and I have some very small shrimp, but I can't tell if they are late hatches from the eggs I originally added or if they are new. I need to figure out a feeding scheme that can sustain a higher density than me pouring in yeast and green water daily. The tank has a single airstone, which doesn't seem to bother them and helps keep the yeast suspended, and no filter.

Very interesting!!!...how was your research? Any update yet?
Thanks before.

They survived to a large size, but I never saw any evidence of reproduction. Some females were seen carrying eggs, but I never got any hatches as far as I know. I never got around to drying out the tub to see if there were winter eggs in the bottom though.

i have been growing redtail fairy shrimp for a few years now. you can generaly get them to hatch out again by doing a 100% water change. they dont all hatch, only a small percentage of the eggs, but in my 5 gallon tank i have them in, it is enough to give me a couple hundred new nauplii. if i dry my tank out completely, i would lose about 90% just because of the small size of the tank.
