To begin, obtain 0.25 grams of Artemia cysts and rinse them with 2.4 grams per liter sodium hypochlorite for five minutes. Filter the rinsed cysts with a sterilized ultra dense filter and wash with sterilized ultrapure water for one to two minutes. After three washes, transfer them to 100 milliliters of 2.5%sterile saline and mix well.
Pack 50 milliliters of treated Artemia cyst mix into a sterile 100-milliliter bottle. Using a film, seal the bottle thoroughly and place it in a shaking incubator with light. Next, using a Pasteur pipette, extract 30 milliliters of hatching Artemia nauplii from the middle and lower layers.
After filtering, wash the Artemia three times with sterile ultrapure water for about one minute, and add four milliliters of sterile ultrapure water. Finally, using a disposable Pasteur pipette, retrieve actively swimming Artemia from the upper layer, wash, and prepare the solution for feeding. Microscopic observation confirmed efficient hatching of Artemia cysts after the treatment.
