How to Hatch Brine Shrimp
This page contains images of baby brine shrimp and information
on how to hatch them
The image to the left shows my home made brine shrimp hatchery. It is
a simple wooden frame which supports three hatching containers. The containers
are made of plastic soda bottles from which the bottom has been cut off
with a utility knife. The bottoms are inverted and become lids which also
support rigid plastic bubbler tubes. The tubes are inserted through small
holes in each lid and connected to an air pump through a set of valves
(which regulate the air flow).
The brine shrimp eggs will hatch in a solution made from untreated tap
water, any non-iodized salt (table salt works fine), and baking soda. I
make up about 5 gallons of solution at once and use it over several days.
I use 15 cc (1 tablespoon) of salt per liter of water. I use about 15 cc
of baking soda per 5 gallon bucket. The latter is not at all critical.
Depending on the temperature in my garage I keep a 40W or 60W bulb on
at all times within about 15 cm of the hatching containers. I always run
two containers at a time, and start one batch in the morning and one at night.
24 hrs. at 85-90 F is enough time for a good yield. The newly hatched shrimp
will live for several days without food but I always use them in the first
48 hrs. (and usually after only 24 hrs.). After that time the nutritional
value decreases as the brine shrimp consume their own "yolk sacks". I never
feed them. The large brine shrimp sold at pet stores are fed yeast (if cultured)
or algae (if harvested from the wild).

I feed my angelfish fry only newly hatched brine shrimp for the first two
weeks after they become free swimming. I then introduce them to very
small amounts of finely ground flake food over the next two weeks
(a little bit before each feeding of brine shrimp). It is then possible
to completely "wean" the fish to flake food. Continued occasional feeding
of brine shrimp will ensure they have adequate beta carotene in their diet
which helps in the early development of yellow, orange, and red pigment.

swimming for five days. A bite size treat. Uneaten live brine shrimp
will live in fresh water for several hours. They are not only a nutritious
food source, they are very unlikely to introduce dangerous parasites to
a fresh water tank since they are raised in salt water.
