This study evaluated the feasibility of cultivating the microcrustacean Artemia parthenogenetica from the Aral Sea population in
artificial ponds using the microalga Dunaliella salina as the sole feed source. It was shown that on a monodiet of D. salina
biomass, Artemia successfully developed to sexual maturity and the cyst-formation stage: females with egg sacs were observed
from day 12, and by day 19, the survival rate stabilized at approximately 80%, with females producing 8-24 nauplii. A decrease
in temperature to 16-18 °С after day 21 induced the transition to cyst laying. Overall, the growth, survival, and reproduction
parameters were consistent with published data; however, a slight extension of the sexual maturation period was noted.
