Hatching Brine Shrimp

New project: Raising Brine Shrimp

UPDATE: Although I think set-up was correct and Brine Shrimp did hatch, they didn’t last long. I might try this again in the summer when it’s warmer. I wanted the Brine Shrimp to reach adulthood to feed my fully grown fish.

So I sometimes feed my fish frozen Brine Shrimp. And recently realised people raise them live, to feed their fish and the fish love them.

You can hatch baby Brine Shrimp straight from the dormant eggs to feed your fish fry, as the swimming motion of the shrimp make the fry instinctively eat them so it’s easier to feed them up, whereas something like crushed up flake may not be as appetising to the baby fish.

Brine Shrimp Eggs

The eggs are literally like sand, and can stay dormant like this for roughly 25 years. Then once added to salt water they can they hatch in 24 hours.

What I’m hoping to do is raise the Brine Shrimp up to adults so they’re a bit larger to feed my adult White Cloud Mountain Minnows (WCMM).

And it can be pretty easy considering you get the parameters right.

So at first I bought some ‘live’ adult Brine Shrimp and tried to raise them so they populate into the masses.

First thing I did was feed a few to my fish, my WCMM and they pretty much eat them instantly.

So that was that, Im setting up more containers full of water to do with things involving fish.

Firstly I added the live Brine Shrimp to, two large water bottles and some Spirulina, unfortunately they didn’t last longer than a couple days.

However I’v now bought a 4.2 litre food container and Iv set it up as a Brine Shrimp hatchery.

Container to hatch brine shrimp eggs

All you do is add an airline to the water (without the air stone as the smaller bubbles can kill the Brine Shrimp if they ingest them). So there are larger bubbles making the eggs suspend in the water constantly so they hatch.

So more specifically; I added 1 3/4 table spoons of aquarium salt per litre. And then added 1 gram of Brine Shrimp per litre. That’s a lot of brine shrimp eggs.

The eggs I bought off eBay have a 90% hatch rate so if done properly there should be a load of Brine Shrimp swimming around, exciting.

But this is the first time so I guess I’ll see what happens. The eggs are like sand so you can buy thousands, (10 grams) for roughly £3-£5 and just keep experimenting if you fail to hatch or raise them.

I’ll update on the results in a couple of days.
