Premium Grade Brine Shrimp Eggs ( 90%)
We guarantee a minimum hatch-out of 255,000 nauplii (baby brine shrimp) per gram of cysts following a 24 – 36 hour incubation period. Based on the most recent harvest, this equates to an average hatch-out of over 90%.
Brine shrimp eggs are the most valuable nutrition product in global aquaculture. To ensure the best possible start in life for fish or shrimp fry, freshly hatched brine shrimp nauplii (Artemia nauplii) are used by millions of professionals in fish breeding and in industrial fish farming all over the world. Because of their resistance to water salinity you can use them in both marine and freshwater tanks.
– INCUBATION INSTRUCTIONS: Prepare an incubation tank, using a conical-shaped vessel recommended. Add 1 teaspoon of brine shrimp eggs (2 to 3 g) to 1 liter of saltwater (use 25 to 30 g salt per 1 liter of water), with a pH level of 8.5. Incubate with constant aeration and water temperature 26- 32 ° C. Lowering the temperature would result in a longer hatching time. Maintain a light level of 2000 lux (Illumination is necessary to trigger the hatching mechanism within the embryo during the first few hours of incubation. Maintaining a light source during the entire incubation period is recommended to obtain optimum hatch results and for temperature control). The incubation period is 24 – 36 hours. Be sure to use marine salt or solar salt.
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 net or sieve using clean fresh or salt water is important before feeding them to your fish.
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.
– STORAGE CONDITIONS: for maximum preservation of product quality, store at temperatures from – 20 ° C to + 20 ° C. Freshly hatched nauplii should be kept in the refrigerator and fed within 24 hours.
