| Species | Development state | Trait | Primary Data | Secondary Data |
| Barbus barbus | Larvae | Temperature during larval development | 19-20 | 19.5 °C |
| Barbus barbus | Larvae | Onset of exogeneous feeding | About 130-140 [7 days at 19.2-20] | 135.0 °C * day |
| Chondrostoma toxostoma | Larvae | Onset of exogeneous feeding | 70-80 [4 days at 16-18°C] | 75.0 °C * day |
| Leucaspius delineatus | Egg | Egg size after water-hardening | 1.3-1.4 [After swelling] | 1.35 mm |
| Leucaspius delineatus | Egg | Egg adhesiveness | Adhere to other eggs in the strip, highly adhesive chorion | Adhesive |
| Leucaspius delineatus | Egg | Incubation time | 3-3.5 [At 24.7°C], also described as 6-7 days [At 21-22°C], and 4 [At 25-26°C] | 3.25 days |
| Leucaspius delineatus | Egg | Temperature for incubation | From activation to hatching, water temperature ranged between 22.8 and 26.5°C | 22.8 °C |
| Leucaspius delineatus | Egg | Degree-days for incubation | 75.5-80.7 | 78.1 °C * day |
| Leucaspius delineatus | Larvae | Initial larval size | Mean 5.11, range 4.83-5.27 | 5.05 mm |
| Leucaspius delineatus | Larvae | Larvae behaviour | The earliest embryos to hatch were onyl able to perform sudden bursts of activity and appeared to be able to swim a few centimetres from the bottom before sinking again. Those embryos that hatched lated, however, were able to perform more sustained swimming that were soon able to swim to the surface | Demersal |
| Leucaspius delineatus | Larvae | Temperature during larval development | After hatching free-embryos and larvae in the aquarium were subsjected to temperatures ranging between 15.1 and 27.5°C, with mean daily temperatures ranging between 16.9 and 26°C (mean 21.6°C). | 15.1 °C |
| Leucaspius delineatus | Larvae | Full yolk-sac resorption | 90-100 DD: By day 8, only a small portion of yolk reserves remained to be absorbed (less than 75.5-80.7 hours for incubation) at 21.6°C | 95.0 °C * day |
| Leucaspius delineatus | Larvae | Onset of exogeneous feeding | Onset of exogeneous feeding for the first embryo 88 hours at 21.6°C] .i.e. 3-16 hours after hatching | 9.5 °C * day |
| Leucaspius delineatus | Spawning conditions | Spawning water type | Sunbleak typically lay their eggs on marginal macrophytes that generally grouw out of anoxic silt | No category |
