Lyle, A.A and Maitland, P.S. (1997) The spawning migration of smelt Osmerus eperlanus in the river Cree, southwest Scotland. Biological Conservation, pp. 303-11
| Species | Development state | Trait | Primary Data | Secondary Data |
| Osmerus eperlanus | Spawning conditions | Spawning migration distance | Smelt are relatively weak swimmers compared with many other migratory fish, and whithin the full spawning area there are major riffles which can be effective barriers to smelt migration without the benefit of a tidal lift | No data |
| Osmerus eperlanus | Spawning conditions | Spawning season | The dates of first spawning ranged between 22 February and 15 March, a span of 22 days [Aslo described as commencing on 9-10 March] | ['February', 'March'] |
| Osmerus eperlanus | Spawning conditions | Spawning period duration | Last about 1 week, | 1.0 weeks |
| Osmerus eperlanus | Spawning conditions | Spawning temperature | Spawning only occurred when temperatures measured in the River Cree were >6°C. However, in 1995 first spawing took place at a temperature below 6°C | 6.0 °C |
