HR Premium Brine Shrimp Eggs (Artemia)

HATCHING PROCEDURES

The following steps will achieve optimum brine shrimp hatch rates.

***Helpful Hint:

Brine shrimp egg is sometimes very buoyant. In order to maximize the hatching percentage, it is sometimes helpful to swirl the water inside the hatching container with your finger once or twice at intervals in the first 4 to 6 hours of incubation in order to knock down eggs that have been stranded on the side of the container above the water-line. After about 6 hours, the eggs are usually well-hydrated and will stay in the water column.

Set Up:

Place hatching cone or similarly shaped vessel in well-lit area. Cone should be semi-translucent for ease of harvesting and light transmission.

Add Water: Fill cone with water and add in 15g of coarse salt for 1 liter of water. Optimum hatching temperature is 28°C.

Add Cysts: 5 gram per liter.

Aerate: Provide adequate aeration to keep cysts in suspension.

Hatch: Depending upon water temperature, cysts should hatch in approximately 30-36 hours.

Harvest: After hatching brine shrimp, turn off or remove aeration and wait several minutes for the shells and and baby brine shrimp (or nauplii) to separate. Newly hatched nauplii will settle to the bottom of the cone or move towards a light source; the shells will float to the surface. Once separated, the nauplii can be siphoned from the bottom with a length of air tubing or gently drained through the bottom of the cone through a valve, if so equipped.

Rinse: The warm incubation temperatures and metabolites from the hatching medium create ideal conditions for a bacteria bloom. Rinsing of the baby brine shrimp in a fine mesh

Feeding: Feed them the amount that your fry is able to finish it within 5 minutes.

STORAGE GUIDELINES

In a tightly sealed container, free from moisture, and in a cool environment at or below 10 degree celsius. (Refrigeration is ideal for short term storage, i.e., less than three to four weeks; for longer term storage, eggs are best kept at or below freezing.)

We recommend to divide the eggs into smaller portion that will be used within 1 month in a tightly sealed container refrigerated and the remainder, also in a tightly sealed container, store in the freezer. Freezing will slower the metabolic rate of the eggs, we recommend to take them out and leave it at room temperature a day advance prior to hatching.
