Here Is My Way, To Raising Brine Shrimps,
In Numbers, Of Around 5,000-7,000 per l/t.

It took me some 30 years before I could truely say I was able to produce, ( and at will ) B/shrimps in large numbers,
and with in smallish containers, and as cheaply as It could be done,

Enough said, this Is not going to be a long winded narrative, of my years of research, which have mostly ended up in cul-de-sac's,
So hear we go.

first choose your Brine shrimps eggs, there are many types.
by far the best for mass production, in my opinion, is the Artemia franciscana forms.

Then choose your salt, it has to be cheap, so plain cooking salt will do, although Table salt works equally as well,
now as for a hatching container, again any will do, I use a 1 Litre jar 1/2 filled with tap water, and as my water is v/soft, I add a little calcium carbonate powder.
to this I then add 1tsp of B/shrimp eggs, one airline no diffuser and depending on temperature 60-90 *f, hatching should occur
with in 16-72hrs.

Now that parts finished, lets get on with the main Job of raising them.

At the same time you set up your B/shrimps hatchery, also set up your raising tank, and the size you choose depends of course
on the amount of shrimps you require, I tend to use 15 - 20 Litre tanks,
and with the addition of the correct dose of compound (see below ) plus two airlines ( no diffusers ) mature the water for 1 to 2 days before use.

10gm to the Litre of cooking salt or Table salt, ( both work )
10gm to the Litre of Magnesium sulphate ( Epsom salts )

Note,.. Try aim for a SG reading between 1.005 - 1.010 .

Note ...no need of exspensive marine salt.

As I have said my tap water is soft, so I add an additional compound of powdered Calcium Carbonate at a rate of 20gm per 5 Litre,
unfortunately the powdered calcium carbonate will make your water a little murky, untill the powder settles down.

( Note,... No....Sodium Bicarbonate is used )

Note,.. One teaspoon full ( approx 3gm ) of B/shrimps eggs, when hatched, should more than fill a 15-20 Litre container when raised

Note,..Airlines must be sitting on the base of the container, so producing a good supply of moving food & surface agitation.

Now If you do have chloramine in your tap water, can I suggest, you use the white powdered compound called Sodium Thiosulphate,
this will quickly nutralise your chloramine problem, even at a low dose of 1gm per 30 Litres of water,
and it will not harm your shrimps.

Required action for feeding, once your newly hatched B/Shrimps nauplii, are added to your culture tank.

Your one and only feed on day one, will be powdered spirulina,( Liquified ) this, when added to your culture should turn it a nice green colour, .
The following morning ( if needed ), add more liquid spirulina to your culture, till again you have acheived a good green colour tecture,
now in the evening of that same day, dose culture with a 1-2gms, of freshly made up liquid yeast,
this addition of yeast should turn your culture more on the milky side.
The next day follow the same agenda, spirulina in morning and yeast in eavening
Keep this action up for approx 5 days , then switch to feeding liquid yeast on both mornings & evenings
Continue this action untill your shrimps have reached there adult size, this should be within 12-14 days at a temperature between 72-76*F,
If your culture starts to give of ammonia,( and it will ) break up your base media ( calcium carbonate powder & uneaten food + shrimp wast ) and
revert back to feeding Spirulina for one day only, or if possible, change a little of the old culture water for fresh.

( yeast mix )
Note ...1/4 cup of warm tap water to which has been added a1/2 tsp of yeast, mix well before use.

( Spirulina mix )
Note...Add a 1/4 - 1/2 tsp of fresh powdered spirulina to a 1/2 litre jam jar, of fresh water from tap, now add cap on jar, and shake well untill we have a frothy surface.
( Always shake jar before use. )
When not in use, keep the liquid spirulina in a fridge, and change the liquid every 3-4 days for fresh .

Note..As said, your culture will smell of a little ammonia most of the time, this will not harm your B/shrimps
if your pH is keeped between 7-8.0 ...

Note...I use a pippet to disperse the spirulina & yeast, as this offers me more controle

And that they say, should be that.

Good luck.


I except no responsibilities for any problems you may encounter,
as these are just the rambling of a mad man
and will be up to you to decide to listen.
