| Species | Development state | Trait | Primary Data | Secondary Data |
| Salmo trutta fario | Spawning conditions | Spawning substrate | Gravel bed | Lithophils |
| Salmo trutta fario | Spawning conditions | Spawning site preparation | Cleaning of a restricted bed area from fine sediments is also achieved by digging salmonid females, which build spawning redds up to 30 cm depth, ensuring sufficient oxygenation of the deposited eggs and for developing larvae after hatching | Susbtrate chooser |
