What are the guidelines for Artemia cysts? Tanks and brine shrimp hatching equipment should be cleaned and disinfected routinely. 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. The warm incubation temperatures and metabolites from the hatching medium create ideal conditions for a bacteria bloom. 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. The egg shells are brown in color and the baby brine shrimp are more orange. Newly hatched nauplii will settle to the bottom of the cone or move towards a light source the shells will float to the surface. Provide adequate aeration to keep cysts in suspension.ĭepending upon water temperature, cysts should hatch in approximately 18-36 hours.Īfter hatching brine shrimp, turn off or remove aeration and wait several minutes for the shells and and baby brine shrimp (or nauplii) to separate. A higher stocking density will result in a lower hatch percentage. Optimum hatching temperature is 82☏ (28☌).Īdd cysts at the rate of 1 gram per liter or quart or approximately 1/2 level teaspoon of cysts per quart is recommended. Cone should be semi-translucent for ease of harvesting and light transmission.įill cone with one liter of water and add 11/2 tablespoons of salt. Place hatching cone or similarly shaped vessel in well-lit area. The following steps will achieve optimum brine shrimp egg hatch rates. Be sure to thoroughly wash the hatching cone with a light chlorine solution, rinse, and allow to air-dry between uses. Cone or "V" bottomed containers are best to insure that the cysts remain in suspension during hatching. A higher stocking density will result in a lower hatch percentage.įlat-bottom hatching vessels should be avoided. A nice steady stream of aeration that tumbles the eggs without pushing them above the water surface and onto the side of the hatching cone.ġ gram per liter or quart or approximately 1/ 2 level teaspoon of cysts per quart is recommended. Illumination can be added to get the best hatching rate, but is not absolutely critical.Ĭonstant aeration is necessary to keep cysts in suspension and to provide sufficient oxygen levels for the cysts to hatch. Lower temperature will result in a longer hatching time, but do not exceed 86☏. Optimum water temperature for a 24-hour complete hatch is 80-82☏. If the pH of your water is below 7, Epson salt or baking soda can be added at the rate of 1/ 2 teaspoon per quart. A starting pH of 8.0 or higher is recommended. Proper pH is important in hatching brine shrimp. Aquarium, sea or non-iodized table salt can be used. This equates to about 1.018 specific gravity as measured with a hydrometer.
