Abstract
This study aimed to investigate the investigation about reproduction of Aphanius dispar dispar (Rüppell, 1829) in Dalaki River, Bushehr. Dalaki River near a Dashtestan city (latitude: 29° 28' and longitude: 51° 17'). A total number of 530 specimens of Aphanius dispar dispar (Rüppell, 1829) were considered, out of which 390 were female and 140 were male. The maximum length was 39 mm for female and 49 for male. Sex ratio of 390 female and 140 male was significant. Observations on the seasonal distribution of maturity stages and variations in seasonal fluctuations in the Gonadosomatic Index (GSI) showed that the spawning period begins in April to June.
