HATCHING METHOD
1. Prepare hatching solution from non-iodized salt or diluted seawater to 20-33ppt (parts per thousand) (1.016-1.024 on hydrometer).
2. Incubate and aerate cysts in a conical shaped container with cyst to solution density not exceeding 2 grams per liter.
3. Provide hatching tank with natural or artificial light and maintain constant temperature of 82 degrees F (28 deg. C)
4. Stop aeration and remove fresh nauplii after 18-24 hours.
Note: If cysts are frozen or held in cold storage while in inventory, allow cysts to acclimate at room temperature for 12 – 24 hours before attempting to hatch.
TROUBLESHOOTING
Enough Light?
A simple fluorescent lamp will provide enough light to attain optimal hatch. Light needs to be constant for the first 12 hours of incubation.
Enough Aeration?
This will depend on how many tanks you are running. Smaller applications can get by with a simple compressor or small blower. Call or email for larger applications.
Constant Temperature?
Immersion heaters with a thermostat is necessary in order to keep a constant temperature of 82-86 degrees F (28-30 deg. C). Call or email for larger applications.
Water Quality?
For smaller applications, use tap water with sea salt (ie: Instant Ocean). Dilute to 20-33ppt. Use a refractometer or hydrometer (1.016-1.024) to measure salinity levels. Larger applications using seawater require filtration systems. Call or email for larger applications.
pH
pH levels should remain at pH8
Storage
The longer you hold Artemia on the shelf, the greater the chance the hatch may diminish. Even Artemia kept under cool, dry conditions will begin to vary its hatch within +/- 3 to 5% over the course of 6-12 months. We recommend that all BIO-MARINE® brand Artemia be kept in a cool, dry place during transport and receiving. Freezer storage is not necessary unless you intend on holding Artemia for more than 6 months. Refrigeration is also not necessary but if the only other alternative mode of storage is at room temperature or if you are in hot and humid conditions, then refrigeration or a well air-conditioned room is highly recommended. We cannot guarantee hatch results for Artemia kept under less than optimal conditions.
OUR GUARANTEE
When you see our logo on the label, you can be assured it is the highest quality egg available. All eggs are tested under strict control to ensure that every cyst of BIO-MARINE® brand Artemia will hatch according to the labeling.
