| Species | Development state | Trait | Primary Data | Secondary Data |
| Pseudorasbora parva | Egg | Egg adhesiveness | Attached eggs | Adhesive |
| Pseudorasbora parva | Female | Length at sexual maturity | The mean (± SD) total length of fish captured in April and used in the experiment was 6.6 ± 0.3 cm (n=68, range 6.0-7.4) for males | 6.6 cm |
| Pseudorasbora parva | Female | Relative fecundity | 253-1733 [Relationships between the total number of eggs laid by individual females and their body weight. The regression equation was Y=986.3 X - 1718.9, Y = number of eggs, X = body weight in April., with weight ranging mainly from 2.0 to 3.5 g] | 993.0 thousand eggs/kg |
| Pseudorasbora parva | Female | Absolute fecundity | The total number of eggs (fecundity) laid by individual females varied from 0 to 6285, different means ranging from 632 ± 805 to 2053 ± 1442 | 632.0 thousand eggs |
| Pseudorasbora parva | Female | Absolute fecundity | In laboratory aquaria, 44 females laid 167 to 6285 eggs in 1 to 14 mating sequences. The fecundity varies between groups from 632 ± 805 to 2053 ± 1442 eggs | 632.0 thousand eggs |
| Pseudorasbora parva | Male | Age at sexual maturity | The fish is sexually dimorphic with males larger than females and reaches maturity at the age of one to two years | 1.0 years |
| Pseudorasbora parva | Male | Length at sexual maturity | The mean (± SD) total length of fish captured in April and used in the experiment was 7.9 ± 0.5 cm (n=68, range 7.0-8.9) for males | 7.9 cm |
| Pseudorasbora parva | Male | Male sexual dimorphism | Males were significantly larger than females | Absent |
| Pseudorasbora parva | Spawning conditions | Spawning season | In Japan, the spawning season lasts from April to August | ['April', 'May', 'June', 'July', 'August'] |
| Pseudorasbora parva | Spawning conditions | Spawning period duration | Spawning occurred from 30 April to 21 August | 30.0 weeks |
| Pseudorasbora parva | Spawning conditions | Spawning temperature | Water temperatures ranged from 11.8 to 27°C during experiments, which was similar to the range of water temperature (from 13.6 to 26°C) when minnow spawned in the reservoir | 11.8 °C |
| Pseudorasbora parva | Spawning conditions | Spawning water type | Ponds and rivers | Stagnant water |
| Pseudorasbora parva | Spawning conditions | Spawning depth | Shallow parts of ponds and rivers | No data |
| Pseudorasbora parva | Spawning conditions | Spawning substrate | Around smooth surfaces of rocks, boulders and plants | Phytophils |
| Pseudorasbora parva | Spawning conditions | Spawning site preparation | Males set up mating territories around smooth surfaces of rocks, boulders and plants | No category |
| Pseudorasbora parva | Spawning conditions | Nycthemeral period of oviposition | Mating does not occur during the night | Night |
| Pseudorasbora parva | Spawning conditions | Mating system | Females usually deposit eggs in several batches in several male territories on a day, and repeat matings several times during the course of a spawning period. When mating, a female moves rapidly along the susbtrate, releasing and attaching to the surface eggs which are inseminated soon after by the territorial males | No category |
| Pseudorasbora parva | Spawning conditions | Spawning release | Is a multiple spawner that lay eggs repeatedly duting the spawning season. | Multiple |
| Pseudorasbora parva | Spawning conditions | Parental care | A territorial male defends eggs until the embryos hatch | Male parental care |
