Baby Brine Shrimp

I've been considering setting up one or two BBS cultures. I've had a lot of tetras spawning lately and keeping fry fed can be difficult. It's been nearly 20 years since I last did this and I don't remember much about it other than we used to add a pipette of bleach to each batch and we set up fresh cultures every day or so because they're only nutritious within the first day of hatching. I also remember that they SMELLED if the culture went off in any way (not excited about that part.

Has anyone here been doing this regularly? What tips do you have? What equipment do you recommend?

I have started micro worm and banana worm cultures. It is super easy and the fry just love it. I'll be happy to give you some and set you up if interested. I much prefer it to BBS

I have microworms. They're too big for tetra fry. I don't know much about banana worms.

I have done it one three levels, 1) research facility with hundreds of tanks, 2) large tank of fish 3) casual for just a few fish.

equipment necessary for each varies. You will need an air bubbler For all methods. For casual, i like the little brineshrimp hatchery where the hatched brine shrimp swim to the light.

for just one or two tanks i make my own cones using inverted soda bottles. If you are getting serious i suggest ordering cones like this


bleaching is suposed to increase yield but i have never really bothered. For all three, make up sea water using ro preferably, (but i have used tap) and 35grams salt (the best is instant ocean) per liter of water.

add water and eggs to the cone, insert the bubbler and make sure it goes down to the bottom and keeps all the eggs shifting.

the more eggs, the more dense the stock and more likely it will be to get gross. Eggs hatch in 1-3 days depending on temp, the brine need light to hatch.

it should not stink when you collect the bbs.

to collect, remove bubbler wait for eggs to settle, drain unhatched eggs, collect middle layer (bbs) then pour off hatched egg shells. Wash cone every time. You will need multiple hatchers set up 12 hours apart ( for feeding twice a day) use fine net to drain and rinse bbs, we used to use a piece of tshirt held over funnel. resuspend bbs in tank water and feed, if you make too much, you can chill in fridge for 12 hours or freeze in ice cube tray.

Also note, that there are two sizes of naupali and you want the smaller, sfbay variety. I dont know about tetras but
zebrafish are too small To eat bbs until 10-12 dpf. We feed them this powdered food.

you could probably use just this and up the size until they are big enough to eat worms.

Thanks - I think we always used SF bay at the hatchery, but it was a looooong time ago. We had infusoria cultures for very little fry, but I find that adding moss and a bit of leaf litter to a tank can keep really small fry fed with infusoria for the first few days without having to maintain a jar of yuck. I have "golden pearls" and other fry foods that are small enough (in addition to decapsulated BS eggs), but I'm looking for something I can overfeed that will keep swimming for a few hours so that the fry can feed continuously. I also think it would be a good conditioning treat for some of my smaller fish.

I love the pentaire catalog. I should never have requested one, it gives me way too many ideas for how to go bankrupt.

I could give you a starter but it's an awful long drive for just that. There's gotta be someone closer than me that can get you started.

I mean, I could probably go grab a slice of that rotting peach on our tree out front and start a culture from that. I read they just show up.

I've heard they don't so it may or may not work. If it doesn't work out and you happen to come out to Londontowne let me know.
