Artemia growing media

I am currently hatching baby brine schrimp for my newly hatched cory-fry, starting a new culture every other day to have a constant supply. 
After reading an article on Artemia, I have learned, that artemia can be held in a culture, and that nauplia over 7 days of age can be fed with spirulina-powder. But what can I feed the newly hatched nauplia? - I was thinking of yeast (Like the baking-stuf) - A possible solution, You think? Think it would be a nice life food for my bigger cories with some bigger artemia. I have also read that a culture of artemia will lay eggs that hatch without being dryed first, so I guees a constant running culture is possible? Ideas and input appreciated. Allan

Artemia use most of their stored energy (which is what makes them such an excellent young fry food source) in building their "shells". Once they've managed that at about 2 days, they become largely inedible for the fish and are more of a treat food, than a truly nutritous conditioning food, IMO. You'd be better served culturing red wiggler worms and feeding the small ones to the fish.

Ahh okay, thanx for the input. But just for fun then, I would like to see these little fellows grow into adult size "seamonkeys"

- As a true aquarist, I like to culture all watery beeings.

Allan you can use yeast but it's very easy to overfeed which will crash the water quality. Best is if you collect real seawater and leave it in the sun to grow even more microscopic life if you can. Drip feed this in to feed the growing shrimp. Just think of them as baby fish if your already used to raising small fry. I used to raise 1-2 litres (solid) of adult brine shrimp per week in small pools when I had time. They would reproduce but I'd still have to top up with tinned eggs/cysts periodically.

I disagree.

Breeding adult brine shrimp may be an excellent live food for larger fishes even though they are not as nutritious as the nauplii. However I do agree if you are going to feed brine shrimp to small growing fish (as in this case) it's best using very young Brine shrimps.

Thanks for the input and the link to the article!

- And yes, as I said in my original post, I was aiming to feed the adult fish with the cultured artemia. I will still hatch artemia for my fry.

I will try to feed with yaest and also add a little bit seawater for the right bacteria to get running.
