Four types of Artemia cysts were reared in the experiment for investigating bacterial causes and problems facing artificial spawning of Artemia in the way of obtaining Artemia population. It was established close recycling water rearing unite consists of ten aquaria as system for culturing. Rice bran suspension, yeast suspension and soy bean milk suspension were examined as feed for rearing. Soy bean milk suspension was the fastest metamorphosis and the highest cysts production.Bacteriological examination of sea water revealed at of a 260-280 C.f.u. / mlin the dilution of 1/100000 equal to 2.6-2.8x10⁷and that was one of causes which may affect hatchability of the cyst. Using of probiotics was better than using of antibiotics in culturing of Artemia for disease control.
