This study was aimed to observe the correlations among egg, larvae and maternal characteristics of Persian
sturgeon. A total of 41 females were used and the variables including fertilization rate, incubation survival rate,
larvae survival rate during yolk sac absorption (before feeding), and larvae survival rate after first feeding were
determined. As a result, fertilization rate was positively correlated with three variables: incubation survival, larvae
survival during yolk sac absorption, and GSI (gonadosomatic index). Also, maternal size (age, weight, total length)
did not show a significant relation (P > 0.05) with incubation survival, larvae survival during yolk sac absorption
and larvae survival at first feeding stage.
