| Aphanius iberus | Male | Resting period | A period of repose from September to February | 6.0 months |
| Aphanius iberus | Spawning conditions | Spawning season | May to August | ['May', 'June', 'July', 'August'] |
| Aphanius iberus | Spawning conditions | Spawning period duration | 14-16 [From May to August] | 15.0 weeks |
