Abstract: 

This study was carried out to determine reproductive conditions of large-scaled barb in the Shapoor River in Boushehr from January 2009 to January 2010. 891 pieces of fishes were caught by gill nets with different mesh sizes. The results showed that 7+ was the oldest age group. Fishes became mature at 2 years old. The maximum length of the caught fish was 691 mm, having absolute fecundity of 65000. The reproductive effort was calculated. It increased with age so that it increased from 2 years with 68.8 to 5 years with 82.1 and then decreased so that it became 80.2 in 6 years old. Gonadosomatic index (GSI) was calculated for both sexes. Female fishes gained spawning peak at two stages so that first peak was in April and second peak in June.
