| Leuciscus cephalus | Spawning conditions | Spawning period duration | At the end of the observation of gonads, it was determined that the fish has laid from May to the end of June. In other studies, described as between April and May, and if the altitude is more than 1000 meters, spawning occurs in June | 1000.0 weeks |
| Leuciscus cephalus | Male | Onset of spermatogenesis | After August, the gonads began to develop and the values of GSI again started to increase gradually until November | ['August', 'November'] |
| Leuciscus cephalus | Female | Relative fecundity | Linear increase between fecundity and weight: n=1588.6+120.53 x W | 1588.6 thousand eggs/kg |
| Leuciscus cephalus | Female | Onset of oogenesis | After August, the gonads began to develop and the values of GSI again started to increase gradually until November | ['August', 'November'] |
| Leuciscus cephalus | Egg | Oocyte diameter | The highest mean egg diameter was found in May (1.04 mm) and the lowest values was found in July (0.46 mm). Eggs diameters were determine din other studies at 0.78-1.20 mm, 0.55-1.38 mm, 1.03 mm, and 0.83-1.50 mm | 0.99 mm |
| Leuciscus cephalus | Female | Absolute fecundity | The mean fecundity was found to be 1158 in age group II and 28664 in age group VII. In other studies, described as: 1909-15680, 1960, 61808, 13269-59200, 2050-20140 eggs | 8794.5 thousand eggs |
| Leuciscus cephalus | Female | Weight at sexual maturity | Means of 11.44 g [Age 2], 47.05 [Age 3], 71.15 [Age 4], 114.60 [Age 5], 159.9 [Age 6], and 240.3 [Age 7] for females | 11.44 kg |
| Leuciscus cephalus | Female | Length at sexual maturity | Means of 95.6 [Age 2], 153.1 [Age 3], 175.9 [Age 4], 206.0 [Age 5], 226.2 [Age 6], and 258.5 [Age 7] for females | 95.6 cm |
| Leuciscus cephalus | Spawning conditions | Parity | Maximum ages observed were VI in males and VII in females | No category |
