Abstract

This study was carried out in Babolrood river (Mazandaran province) from 5 September 2008 to 6 August 2009 on LEUCISCUS CEPHALUS (mahi sephid rood khanei). The sampling was montly and samples were collected by Electroshocker. In total 441 LEUCISCUS CEPHALUS were caught. Maximum fish abundance in stage 3 with 21.02 percent and the lowest number in SEX MATURATION stage 6 with a frequency of 8.55 percent were. Maximum number of fish in terms of male gender in SEX MATURATION stage 3 with the frequency of 20.55 percent and the lowest number was in step 6 with a frequency of 7.22 percent.The highest percent of female, in SEX MATURATION stage 3 with 21.34 percent and the lowest number in step 7with a frequency of 8.70 percent were found.The mean diameter of oocytes in female fish from November to May was in ascending trend and mean was in May (69.83±12.90 m). The absolute fecundity minimum was 3005, maximum was 13194 and mean egg number was estimated to be 8038.The average percentage of gonado somatic maturation index (GSI) for males was 1.47±0.94, for female was 2.95±1.83 respectively. The total mean of condition factor (CF) was evaluated to be 1.12±0.14 for males and 1.17±0.15 for females. According to this review spawning time is from mid-May to late June and their spawning type once a time.
