ARTEMIA CYST HATCHING
· Use a transparent or translucent cylindroconical cone or tank.
· Supply air through open aeration line down to the tip of the
conical part of the tank.
· A valve at the tip of the tank will facilitate the harvesting of
the live artemia.
· Hatching temperature of distilled water, (28 Celsius) (84
Fahrenheit).
· PH should be 8.75to 8.85.
· Salinity should be 20-30 parts per thousand (ppt) salt solutions
or approximately 3% salinity.
· Illumination should be 2000 lux at the water surface, entire 24
hour hatching period.
· The density should be 1.6 gram per litre warter.
· The hatching time should be 24 hours.
· Storage -15 to 6 Celsius for up to 6 months. Keep out of direct
sunlight.
. If you take the artemia cysts from storage, please keep 12 hours
outside, then to hatch.
· Use open cans as soon as possible.
HATCHING IN HATCHERIES
Start with any clean see through container. For large hatcheries,
large conical shaped containers work best.
Hook up an air hose from the air pump so that it bubbles from the
bottom of the container. Fill with clean filtered or treated water.
Add salt to prepare water to specific gravity of 1.022. Clean
filtered sea water may be substituted. Bubble the solution gently.
When the salt has dissolved, add the specified amount of Artemia
eggs. Keep the bubbling solution at (80 degree F) 28 degrees C,
making sure the eggs are moving within the solution for *24 to 36
hours.
Shut off the air and let settle for 10 min. Harvest the live baby
shrimp Nauplii from the middle of the water by suctioning with a
tube into a tight weave material net. Rinse the salt off with clean
water and feed directly into the aquarium or growing tanks
immediately.
*Note: 90% of the eggs will hatch within 24 hours, but some
hatcheries
prefer to wait 36 to 48 hours for a complete hatch before
harvesting.
