Abstract:
Artemia urmiana
has been reported from the
Urmia Lake by Günther in 1899. The objectives of this
study were to investigate the diameter of untreated and
decapsulated cysts and chorion thickness in 26 stations
of the Urmia Lake. One-Way ANOVA (Tukey Test, p<0.05)
was used, for analyzing the data. Only 31 pair means of
untreated cysts among 26 stations showed significant
differences, but, on the other hand, 157 pair mean of
decapsulated cysts among stations showed significant
differences. Then there is high variation in cyst
diameter among the different localities in the Urmia
Lake. It has been shown that this lake consists of
recognizable sections producing cysts with different
hatching characteristics, which can be used for diverse
aquacultural purposes.
