| Species | Development state | Trait | Primary Data | Secondary Data |
| Osmerus eperlanus | Egg | Oocyte diameter | The egg, which has a diameter ranging from 0.75 to 0.90 mm | 0.9 mm |
| Osmerus eperlanus | Egg | Degree-days for incubation | The fish hatch as larvae after 17 days at 12°C | 17.0 °C * day |
| Osmerus eperlanus | Larvae | Initial larval size | The fish hatch as larvae at approximatively 4.8 mm total length | 4.8 mm |
| Osmerus eperlanus | Larvae | Full yolk-sac resorption | The yolk sac is fully absorbed at a total length of 8 mm, 9 days after hatching at 17.7°C. Smelt larvae with functional mouth and remaining yolk sac are already capable of performing exogenous feeding. | 8.0 °C * day |
| Osmerus eperlanus | Spawning conditions | Spawning season | Considering these determinations, one can estimate that for 1993, smelt spawned between 22 March and 7 April with a peak spawning effort on 29 March. | ['March', 'April'] |
