and also calculation of block size measurements (weighted joint density and block size). Laboratory test were carried out to determine uniaxial compressive strength and point load values.The block size measurement methods and also RMi and GSI classification...
Fecundity and maturation of South Caspian spirlin, Alburnoides sp. (Actinopterygii: Cypriniade) from Iran
. The mean absolute fecundity of females spirlin was 1722.92 (653.88) eggs. The fecundity has positive correlation with the size of the female. The mean of the monthly GSI index and ovadiameters shows that spirlin spawn once in a year during the months...
