| Species | Development state | Trait | Primary Data | Secondary Data | 
| Abramis brama | Spawning conditions | Spawning season | In the Trent, the main hatching period for bream occurred around the second week of June, with the majority of hatching complete by mid-July | ['June', 'July'] | 
| Abramis brama | Spawning conditions | Spawning release | Adopt multiple spawning strategies, with up to three batches of eggs produced by individual fish | Multiple | 
| Alburnus alburnus | Spawning conditions | Spawning season | In the Trent, the initial hatching period was between mid-June and mid-July, with successive cohorts appearing at intervals thereafter | ['June', 'July'] | 
| Alburnus alburnus | Spawning conditions | Spawning release | Adopt multiple spawning strategies, with up to three batches of eggs produced by individual fish | Multiple | 
| Gobio gobio | Spawning conditions | Spawning season | In the Trent, the main hatching period for gudgeon was between late May and mid-June, with smaller numbers of fish from subsequent cohorts appearing at intervals therefater | ['May', 'June'] | 
| Gobio gobio | Spawning conditions | Spawning release | Adopt multiple spawning strategies, with up to three batches of eggs produced by individual fish | Multiple |

| Leuciscus cephalus | Spawning conditions | Spawning release | Adopt multiple spawning strategies, with up to three batches of eggs produced by individual fish | Multiple | 
| Leuciscus leuciscus | Spawning conditions | Spawning season | In the Trent, dace hatched between the third week of April (2003) and the first week of May (2002), whereas in the Ouse catchment hatching occurred 3 or 4 weeks later | ['April', 'May'] | 
| Leuciscus leuciscus | Spawning conditions | Spawning release | Shed a single batch of eggs in a well-defined spawning period | Multiple | 
| Phoxinus phoxinus | Spawning conditions | Spawning season | In the Ouse catchment, the main hatching period for minnow was around early June, with fish from subsequent cohorts appearing in small numbers thereafter | ['June'] | 
| Phoxinus phoxinus | Spawning conditions | Spawning release | Adopt multiple spawning strategies, with up to three batches of eggs produced by individual fish | Multiple | 
| Rutilus rutilus | Spawning conditions | Spawning season | In the Trent, roach hatched between the end of April (2003) and the beginning of June (2002), but usually in the third and fourth weeks of May | ['April', 'May', 'June'] | 
| Rutilus rutilus | Spawning conditions | Spawning release | Shed a single batch of eggs in a well-defined spawning period | Multiple | 
| Perca fluviatilis | Spawning conditions | Spawning season | In the Trent and Avon, perch hatched at approximately the same time as roach, between the end of April (2003) and the middle of May (all other years) | ['April', 'May'] |
