Artemia Salina

brine shrimps


Brine shrimps (Artemia Salina) are used as a
living food for saltwater fishes. Artemia can be
bought in shops but can be much cheaper produced
by yourself.
Artemia is not very suitable as a food source for
fresh water fishes as the brine shrimps die after
some minutes in fresh water.
Waterfleas are cheaper living food in freshwater.
Artemia are beautiful to see under a miscroscope.


How to make saltwater

Brine shrimps need saltwater, the water need at least
to be as salty as seawater .
This is best done with seasalt used in food or seasalt
used to make seawater for aquaria.
Dont use tablesalt as this gives a lesser result.
The specific weight needs to be more then 1025 .
Take a look at salinity to
know more about producing seawater.
If the specific weight is much higher then 1025,
the shrimps will grow slower but the population
is more stable (recommended).

How to feed brine shrimps :

The eggs need to 2 days to transform into nauplii
or larvae. Feeding the nauplii with musselmilk
(pulverised mussel).
Musselmilk is made by mixing mussels and cooking it.
is the best and cheapest way to feed nauplii.
Mikrozell is a commercial product that is made
for this purpose but very exspensive.
Feeding the artemia can be done with :
- yeast
- wheat flour
- egg yolk
- soybean powder
- Plancton is the natural food, and is especialy good
for the young brine shrimps or nauplii.
The whole lifespan of Artemia is about one year.
the food in the first eight days is exspensive.
For this reason its more economical to feed with
artemia if they are much older.


Altough artemia grow faster at temperatures higher then room-
temperature, bacteria do the same.
Brine shrimps larvae or nauplii are very sensible for
bacterial growth.


One doesn´t need a special illumination to grow youre
artemia. But light can be used to attract the artemia,
they are very fotosensible. illuminate a small part
and the artemia gather in that light spot, and
can be harvested.

using aquaria

Aquaria are best suited to produce artemia.
In this way algae will grow more easely, this
will improve waterquality and plankton is a
good food source for the nauplii.
Another methode is the use of inverted bottles.
In this methode the salanity of the water is the
same as that of the aquarium, so if you feed youre
fishes, the only thing you have to do is to
empty the bottle in the aquarium

Problems in producing artemia

- Don´t use small airbubbles as they stick to
artemia and pulling the shrimp to the surface.
- Overfeeding is the biggest problem, bacteria will
will reduce youre artemia stock.
- If youre artemia population suddenly dies, a virus is
the cause.
Don't feed the artemia eggs to youre fish
- A good indication for the health of youre brine
shrimps is there reaction to light, the quicker,
the more healthier.
If there reaction is slow the most obvious cause
is overfeeding. Artemia has to be pink or yellow,
if they are red then theres a lack of oxygen .

How to improve

Keep the water at a PH of 8 or 9 , this is most easely
done by adding some lime stones.
Use the artemia franciscana instead of the artemia
from Salt lake. Artemia franciscana is adapted to lower
temperatures and more stable.
Don´t use much light, as artemia are strongly
attractedto light and waste energy in that way.

the Artemia factory

Artemia can be produced cheapely and most efficient
by using two aquaria: a large one for the production
of plankton and to clean the water, and a small one
for the production of artemia.
The artemiafilter keeps the artemia out of the large
aquarium. The water from the large aquarium is
transported to the smaller by using an airbubble lift.
Producing artemia this way is cheap. Biggest problem
is the filter that need to be cleaned often.

You need a airbubble lift, as an electrical pump wood
kill the algae by its propellor. An airbubble lift
is a tube in which air is pumped at the underside
of the tube. The airbubble produces a flow of water
to the upperside of the tube.
The airpump is the same (membrame)pump as used in aquaria,

artemia and closed systems

These are small aquaria or jars completely sealed
off from the outside world.
Brine shrimps and Halobacteria can stay alive in
such a closed systems for years (sea monkeys ).
Such a closed system can be given as a present
to patients in Hospitals or inmates in a prison.
take a look at closed systems.

    Artemia and salt

    Artemia are worldchampion in osmoregulation: it can remove
    salt from its body like no other animal can: And no other
    animal can survive in such salty envirronment.
    They can also adapt to quick changes in salinity,
    caused by rainfall (monsoons).
    Those high levels of salt protect them from predators.
    The shortage in world supply of Artemia cysts or eggs,
    due to the unstable harvest at the Great Salt Lake have
    resulted in a very high price for Artemia cysts in 1970.
    Since then ,third world lands like India have started
    to produce Artemia cysts.

    The production of salt in India is mostly done by human labor.
    The competition with industrial produced salt makes it hard
    to find a living. One third of all saltproduction is done

    in those salt works and India is by far the largest producere of seasalt.

    China is the largest salt producer ,surpassing USA. China
    and India are the fastest growers.

    saltworks: salt and Artemia

    There are 2 miljon ha of salt works in India along the
    coastline that could be used for the prodction of artemia.
    Experimental use of these saltworks resulted in
    a production of 4kg of artemia cysts/ha.

    Gujarat and Tamil nadu are the largest production area's
    in India, although saltworks can be found everywere along
    the long coastline of India

    The sea saltproduction in India is for a large amount done by small companies.
    Most of the production for the use in India itself
    12 kg /each person/year is needed for own salt
    consumption. The distribution is mainly done by train.

    Artemia in saltworks

    The most often used strain of Artemia is the Artemia
    franciscana. There are three ways to use artemia and other
    organism that flourish in the brine of saltworks:
    1 to enhance the salt
    production by changing the color of the saltpan:
    In this way the evaporation will increase and so the
    2 to produce artemia cyst
    3 to produce shrimps that feed on artemia

    salt harvested
    salt in the evaporation saltpan.

    Salt production in saltpans.

    Lets start with the normal saltproduction in those saltpans:
    This is nowadays done in three phases:
    First: seawater is pumped in the nurse or evaporation ponds.
    Sea water in India is rich in nutrients, evaporation makes the
    water more salty until it becomes brine. An algae bloom makes
    the salty water a fine place to produce shrimps.
    Seconds: As the water gets more salty , only artemia survives
    as the most important predator. Gypse salt can also be harvest
    third: in the last stage halobacteria colors the water red ,
    the purple bacteria gives a purple shine, increasing the sunlight
    thats absorbed and thus accelerate the evaporation speed.

    Artemia production in evaporation or nurse saltpans

    The saltpans that contain brine are a good place for the production
    of artemia, the brine gives predators little chance.
    The artemia cysts float on the water surface and are
    washed ashore by wind and waves. The collection of
    them is done by employ workers who
    harvest artemiacysts by a dip net.

    Live in a saltpan

    A saltpan can be used for the production of shrimps and fishes.
    The saltpans that are low on salinity are very well suited for
    that, the shrimps can be feeded with chicken manure and Artemia.
