Brine Shrimp/Artemia Hatching and Raising to Adulthood
I have been experimenting with raising brine shrimp. The hatching part is really quite simple and although a part of the process i am more interested in feeding fish rather than fry so looking to raise them to adulthood. Raising them to adulthood, for me, is proving to be difficult to say the least. But due to my nature i will not stop until I've managed to successfully raise them to adulthood in worthwhile numbers.
I'm posting my efforts in a video diary on you tube. I would be more than grateful for any advice and comments.
Hello and welcome to TFK :-DFrom my understanding adult brine shrimp actually have very little nutritional value, it is the baby brine shrimp that are full of nutrition. Good luck.
I was under the very same impression about the nutritional value of adult brine shrimp. I understand the nutritional value of the newly hatched brine shrimp/nauplii is rich in mainly fats which is beneficial to the growth of fry, but then as they reach adulthood the brine shrimp are more packed with protein which is good for adult fish. I've also read that the food you feed the brine shrimp when raising plays a significant role in their nutritional value and therefore their nutritional value as a food source for fish. There is so much information available about all aspects of raising brine shrimp, unfortunately much of which seems more like mis-information. This is one of the main reasons I've started studying aquaculture.
Oh and thankyou for your kind welcome.

I am very much looking forward to seeing your results with raising brine shrimp to adulthood. I purchased the Brine Shrimp Direct Hatchery Dish myself and followed the instructions to a successful yield, but it seemed the baby brine shrimp were too small for all but the blue green chromis in my saltwater tank. I wondered about raising them to maturity and then trying to feed them to my larger fish, but the thought of setting up an ecosystem just for that purpose seemed too much. I'm curious to see your results and how long it takes to raise brine shrimp to a size suitable for consumption by fish larger than fry or other small fish.
I'm studying aquaculture to ensure that my experiments at raising brine shrimp are as successful as possible. What I'm also hoping to show with my experiment is that the whole process can be carried out with the simplest of methods in the average home.

So lets look all the required parameters to raise brine shrimp to adulthood.
Water: We'll need a hydrometer to ensure we maintain the correct salinity. Use sea salt if/when mixing. We'll also need some kind of filtration or water changes as required to ensure decent water quality - above all, do not overfeed!
Oxygen: An air stone on very low at one corner of the tank.
Food: real or powdered algae, brewers (or active?) yeast, some say wheat flour and (powdered?) egg yolk may be used. Brine shrimp are filter feeders, so they do not have mouths that chew.
The food will be key in producing a nutritious shrimp for our fish.
It will be about 4 weeks from hatching to maturity. Under good conditions, they might be bred to produce a near endless supply.
Having written the above, I saw a youtube video where a fella hatches brine shrimp and puts the contents in a bucket outside where it gets morning sun, covered with florescent light plastic cover and feeds with dried algae (no air stone, no filtration). He rotates a few of these buckets and periodically nets adult brine shrimp to feed fish. Although seasonal, his process seems pretty effortless. The (morning) sunlight affords warmth as well as promotes some natural algae.
I have often wondered about the extension of the hobby that raises live food for fish. Brine shrimp, daphnia, worms... Long ago, I hatched brine shrimp for fry and did grow some to adulthood using yeast, but these days I buy frozen and it always creates a feeding frenzy ;-)
