| Species | Development state | Trait | Primary Data | Secondary Data |
| Pseudorasbora parva | Male | Length at sexual maturity | Mature males used were 5.95 ± 0.95 cm | 5.95 cm |
| Pseudorasbora parva | Male | Weight at sexual maturity | Mature males used were 3.76 ± 1.77 g | 3.76 kg |
| Pseudorasbora parva | Spawning conditions | Spawning temperature | The stock tanks were maintained on a constant photoperiod of 14 h light (from 07:00 to 21:00) and 10 h of dark at 20°C | 14.0 °C |
| Pseudorasbora parva | Spawning conditions | Spawning site preparation | In Pseudorasbora, a mature males establish a territory around spawning susbtrates (e.g., stones, plants or shells) onto which females will deposit their eggs. Almost all dominant males attacked other males with aggressive behavior such as chasing, head butting, or circling between males | Susbtrate chooser |
| Pseudorasbora parva | Spawning conditions | Parental care | The males entices several females to lay their eggs, fertilizes the eggs and guards the fertilized eggs until the embryos hatch | No category |
